How This API Document Is Organized

This API (Application Programming Interface) document has pages corresponding to the items in the navigation bar, described as follows.
Overview

The Overview page is the front page of this API document and provides a list of all packages with a summary for each. This page can also contain an overall description of the set of packages.

Package

Each package has a page that contains a list of its classes and interfaces, with a summary for each. This page can contain four categories:
Interfaces (italic)
Classes
Enums
Exceptions
Errors
Annotation Types

Class/Interface

Each class, interface, nested class and nested interface has its own separate page. Each of these pages has three sections consisting of a class/interface description, summary tables, and detailed member descriptions:
Class inheritance diagram
Direct Subclasses
All Known Subinterfaces
All Known Implementing Classes
Class/interface declaration
Class/interface description

Nested Class Summary
Field Summary
Constructor Summary
Method Summary

Field Detail
Constructor Detail
Method Detail

Each summary entry contains the first sentence from the detailed description for that item. The summary entries are alphabetical, while the detailed descriptions are in the order they appear in the source code. This preserves the logical groupings established by the programmer.

Annotation Type

Each annotation type has its own separate page with the following sections:
Annotation Type declaration
Annotation Type description
Required Element Summary
Optional Element Summary
Element Detail

Enum

Each enum has its own separate page with the following sections:
Enum declaration
Enum description
Enum Constant Summary
Enum Constant Detail

Tree (Class Hierarchy)

There is a Class Hierarchy page for all packages, plus a hierarchy for each package. Each hierarchy page contains a list of classes and a list of interfaces. The classes are organized by inheritance structure starting with java.lang.Object. The interfaces do not inherit from java.lang.Object. When viewing the Overview page, clicking on “Tree” displays the hierarchy for all packages.
When viewing a particular package, class or interface page, clicking “Tree” displays the hierarchy for only that package.

Deprecated API

The Deprecated API page lists all of the API that have been deprecated. A deprecated API is not recommended for use, generally due to improvements, and a replacement API is usually given. Deprecated APIs may be removed in future implementations.

Index

The Index contains an alphabetic list of all classes, interfaces, constructors, methods, and fields.

Prev/Next

These links take you to the next or previous class, interface, package, or related page.
Frames/No Frames

These links show and hide the HTML frames. All pages are available with or without frames.

Serialized Form

Each serializable or externalizable class has a description of its serialization fields and methods. This information is of interest to re-implementors, not to developers using the API. While there is no link in the navigation bar, you can get to this information by going to any serialized class and clicking “Serialized Form” in the “See also” section of the class description.

Constant Field Values

The Constant Field Values page lists the static final fields and their values.

This help file applies to API documentation generated using the standard doclet.

Constructor Detail

IntroToTools

public IntroToTools(String title,
String heading)

Simple constructor, likely used to run a stand-alone memory reference visualizer.

Parameters:
title – String containing title for title bar
heading – String containing text for heading shown in upper part of window.

IntroToTools

public IntroToTools()

Simple constructor, likely used by the MARS Tools menu mechanism

Method Detail

main

public static void main(String[] args)

Main provided for pure stand-alone use. Recommended stand-alone use is to write a
driver program that instantiates a MemoryReferenceVisualization object then invokes its go() method.
“stand-alone” means it is not invoked from the MARS Tools menu. “Pure” means there
is no driver program to invoke the application.

getName

public String getName()

Required method to return Tool name.

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication

Returns:
Tool name. MARS will display this in menu item.

buildMainDisplayArea

protected JComponent buildMainDisplayArea()

Implementation of the inherited abstract method to build the main
display area of the GUI. It will be placed in the CENTER area of a
BorderLayout. The title is in the NORTH area, and the controls are
in the SOUTH area.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

Method Detail

main

public static void main(String[] args)

getName

public String getName()

Description copied from class: AbstractMarsToolAndApplication
Required MarsTool method to return Tool name. Must be defined by subclass.

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication

Returns:
Tool name. MARS will display this in menu item.

addAsObserver

protected void addAsObserver()

Description copied from class: AbstractMarsToolAndApplication
Add this app/tool as an Observer of desired MIPS Observables (memory and registers).
By default, will add as an Observer of the entire Data Segment in memory.
Override if you want something different. Note that the Memory methods to add an
Observer to memory are flexible (you can register for a range of addresses) but
may throw an AddressErrorException that you need to catch.
This method is called whenever the default “Connect” button on a MarsTool or the
default “Assemble and run” on a stand-alone Mars app is selected. The corresponding
NOTE: if you do not want to register as an Observer of the entire data segment
(starts at address 0x10000000) then override this to either do some alternative
or nothing at all. This method is also overloaded to allow arbitrary memory
subrange.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

update

public void update(Observable ressource,
Object accessNotice)

Description copied from class: AbstractMarsToolAndApplication
Called when receiving notice of access to MIPS memory or registers. Default
implementation of method required by Observer interface. This method will filter out
notices originating from the MARS GUI or from direct user editing of memory or register
displays. Only notices arising from MIPS program access are allowed in.
It then calls two methods to be overridden by the subclass (since they do
nothing by default): processMIPSUpdate() then updateDisplay().

Specified by:
update in interface Observer
Overrides:
update in class AbstractMarsToolAndApplication

Parameters:
ressource – the attached MIPS resource
accessNotice – AccessNotice information provided by the resource

reset

protected void reset()

Description copied from class: AbstractMarsToolAndApplication
Method that will be called each time the default Reset button is clicked.
Use it to reset any data structures and/or GUI components. By default it does nothing.

Overrides:
reset in class AbstractMarsToolAndApplication

buildMainDisplayArea

protected JComponent buildMainDisplayArea()

Description copied from class: AbstractMarsToolAndApplication
Abstract method that must be instantiated by subclass to build the main display area
of the GUI. It will be placed in the CENTER area of a BorderLayout. The title
is in the NORTH area, and the controls are in the SOUTH area.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

getHelpComponent

protected JComponent getHelpComponent()

Description copied from class: AbstractMarsToolAndApplication
Override this method to provide a JComponent (probably a JButton) of your choice
to be placed just left of the Close/Exit button. Its anticipated use is for a
“help” button that launches a help message or dialog. But it can be any valid
JComponent that doesn’t mind co-existing among a bunch of JButtons.

Overrides:
getHelpComponent in class AbstractMarsToolAndApplication

Tool to help students learn about IEEE 754 representation of 32 bit
floating point values. This representation is used by MIPS “float”
directive and instructions and also the Java (and most other languages)
“float” data type. As written, it can ALMOST be adapted to 64 bit by
changing a few constants.

Simple constructor, likely used to run a stand-alone memory reference visualizer.

Parameters:
title – String containing title for title bar
heading – String containing text for heading shown in upper part of window.

FloatRepresentation

public FloatRepresentation()

Simple constructor, likely used by the MARS Tools menu mechanism

Method Detail

main

public static void main(String[] args)

Main provided for pure stand-alone use. Recommended stand-alone use is to write a
driver program that instantiates a FloatRepresentation object then invokes its go() method.
“stand-alone” means it is not invoked from the MARS Tools menu. “Pure” means there
is no driver program to invoke the application.

getName

public String getName()

Fetch tool name (for display in MARS Tools menu)

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication

Returns:
String containing tool name

addAsObserver

protected void addAsObserver()

Override the inherited method, which registers us as an Observer over the static data segment
(starting address 0x10010000) only. This version will register us as observer over the selected
floating point register, if any. If no register is selected, it will not do anything.
If you use the inherited GUI buttons, this method is invoked when you click “Connect” button
on MarsTool or the “Assemble and Run” button on a Mars-based app.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

deleteAsObserver

protected void deleteAsObserver()

Delete this app/tool as an Observer of the attached register. This overrides
the inherited version which deletes only as an Observer of memory.
This method is called when the default “Disconnect” button on a MarsTool is selected or
when the MIPS program execution triggered by the default “Assemble and run” on a stand-alone
Mars app terminates (e.g. when the button is re-enabled).

Overrides:
deleteAsObserver in class AbstractMarsToolAndApplication

buildMainDisplayArea

protected JComponent buildMainDisplayArea()

Method that constructs the main display area. This will be vertically sandwiched between
the standard heading area at the top and the control area at the bottom.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

Returns:
the GUI component containing the application/tool-specific part of the user interface

update

public void update(Observable register,
Object accessNotice)

Override inherited update() to update display when “attached” register is modified
either by MIPS program or by user editing it on the MARS user interface.
The latter is the reason for overriding the inherited update() method.
The inherited method will filter out notices triggered by the MARS GUI or the user.

Specified by:
update in interface Observer
Overrides:
update in class AbstractMarsToolAndApplication

Parameters:
register – the attached register
accessNotice – information provided by register in RegisterAccessNotice object

reset

protected void reset()

Method to reset display values to 0 when the Reset button selected.
If attached to a MIPS register at the time, the register will be reset as well.
Overrides inherited method that does nothing.

Overrides:
reset in class AbstractMarsToolAndApplication

public class BHTSimulator
extends AbstractMarsToolAndApplication
implements ActionListener

A MARS tool for simulating branch prediction with a Branch History Table (BHT)

The simulation is based on observing the access to the instruction memory area (text segment).
If a branch instruction is encountered, a prediction based on a BHT is performed.
The outcome of the branch is compared with the prediction and the prediction is updated accordingly.
Statistics about the correct and incorrect number of predictions can be obtained for each BHT entry.
The number of entries in the BHT and the history that is considered for each prediction can be configured interactively.
A change of the configuration however causes a re-initialization of the BHT.

The tool can be used to show how branch prediction works in case of loops and how effective such simple methods are.
In case of nested loops the difference of BHT with 1 or 2 Bit history can be explored and visualized.

public class KeyboardAndDisplaySimulator
extends AbstractMarsToolAndApplication

Keyboard and Display Simulator. It can be run either as a stand-alone Java application having
access to the mars package, or through MARS as an item in its Tools menu. It makes
maximum use of methods inherited from its abstract superclass AbstractMarsToolAndApplication.
Pete Sanderson

Version 1.0, 24 July 2008.

Version 1.1, 24 November 2008 corrects two omissions: (1) the tool failed to register as an observer
of kernel text memory when counting instruction executions for transmitter ready bit
reset delay, and (2) the tool failed to test the Status register’s Exception Level bit before
raising the exception that results in the interrupt (if the Exception Level bit is 1, that
means an interrupt is being processed, so disable further interrupts).

Version 1.2, 6 August 2009, soft-codes the MMIO register locations for new memory configuration
feature of MARS 3.7. Previously memory segment addresses were fixed and final. Now they
can be modified dynamically so the tool has to get its values dynamically as well.

protected void addAsObserver()

Override the inherited method, which registers us as an Observer over the static data segment
(starting address 0x10010000) only.

When user enters keystroke, set RECEIVER_CONTROL and RECEIVER_DATA using the action listener.
When user loads word (lw) from RECEIVER_DATA (we are notified of the read), then clear RECEIVER_CONTROL.
When user stores word (sw) to TRANSMITTER_DATA (we are notified of the write), then clear TRANSMITTER_CONTROL, read TRANSMITTER_DATA,
echo the character to display, wait for delay period, then set TRANSMITTER_CONTROL.

If you use the inherited GUI buttons, this method is invoked when you click “Connect” button on MarsTool or the
“Assemble and Run” button on a Mars-based app.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

buildMainDisplayArea

the Transmitter Data location, 0xffff000c. They keyboard is also a JTextArea
places each typed character into the Receive Data location 0xffff0004.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

Returns:
the GUI component containing these two areas

Field Detail

counter

protected int counter

Number of instructions executed until now.

counterR

protected int counterR

Number of instructions of type R.

counterI

protected int counterI

Number of instructions of type I.

counterJ

protected int counterJ

Number of instructions of type J.

lastAddress

protected int lastAddress

The last address we saw. We ignore it because the only way for a
program to execute twice the same instruction is to enter an infinite
loop, which is not insteresting in the POV of counting instructions.

Constructor Detail

InstructionCounter

public InstructionCounter(String title,
String heading)

Simple constructor, likely used to run a stand-alone memory reference visualizer.

Parameters:
title – String containing title for title bar
heading – String containing text for heading shown in upper part of window.

InstructionCounter

public InstructionCounter()

Simple construction, likely used by the MARS Tools menu mechanism.

Method Detail

getName

public String getName()

Description copied from class: AbstractMarsToolAndApplication
Required MarsTool method to return Tool name. Must be defined by subclass.

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication

Returns:
Tool name. MARS will display this in menu item.

buildMainDisplayArea

protected JComponent buildMainDisplayArea()

Description copied from class: AbstractMarsToolAndApplication
Abstract method that must be instantiated by subclass to build the main display area
of the GUI. It will be placed in the CENTER area of a BorderLayout. The title
is in the NORTH area, and the controls are in the SOUTH area.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

addAsObserver

protected void addAsObserver()

Description copied from class: AbstractMarsToolAndApplication
Add this app/tool as an Observer of desired MIPS Observables (memory and registers).
By default, will add as an Observer of the entire Data Segment in memory.
Override if you want something different. Note that the Memory methods to add an
Observer to memory are flexible (you can register for a range of addresses) but
may throw an AddressErrorException that you need to catch.
This method is called whenever the default “Connect” button on a MarsTool or the
default “Assemble and run” on a stand-alone Mars app is selected. The corresponding
NOTE: if you do not want to register as an Observer of the entire data segment
(starts at address 0x10000000) then override this to either do some alternative
or nothing at all. This method is also overloaded to allow arbitrary memory
subrange.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

processMIPSUpdate

protected void processMIPSUpdate(Observable resource,
AccessNotice notice)

Description copied from class: AbstractMarsToolAndApplication
Override this method to process a received notice from MIPS Observable (memory or register)
It will only be called if the notice was generated as the result of MIPS instruction execution.
By default it does nothing. After this method is complete, the updateDisplay() method will be
invoked automatically.

Overrides:
processMIPSUpdate in class AbstractMarsToolAndApplication

initializePreGUI

protected void initializePreGUI()

Description copied from class: AbstractMarsToolAndApplication
Method that will be called once just before the GUI is constructed in the go() and action()
methods. Use it to initialize any data structures needed for the application whose values
will be needed to determine the initial state of GUI components. By default it does nothing.

Overrides:
initializePreGUI in class AbstractMarsToolAndApplication

reset

protected void reset()

Description copied from class: AbstractMarsToolAndApplication
Method that will be called each time the default Reset button is clicked.
Use it to reset any data structures and/or GUI components. By default it does nothing.

Overrides:
reset in class AbstractMarsToolAndApplication

updateDisplay

protected void updateDisplay()

Description copied from class: AbstractMarsToolAndApplication
Override this method to implement updating of GUI after each MIPS instruction is executed,
while running in “timed” mode (user specifies execution speed on the slider control).
Does nothing by default.

Overrides:
updateDisplay in class AbstractMarsToolAndApplication

mars.tools.AbstractMarsToolAndApplication
mars.tools.CacheSimulator

All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable, Observer, Accessible, RootPaneContainer, WindowConstants, MarsTool

public class CacheSimulator
extends AbstractMarsToolAndApplication

A data cache simulator. It can be run either as a stand-alone Java application having
access to the mars package, or through MARS as an item in its Tools menu. It makes
maximum use of methods inherited from its abstract superclass AbstractMarsToolOrApp.
Pete Sanderson, v 1.0: 16-18 October 2006, v 1.1: 7 November 2006. v 1.2: 23 December 2010.

Version 1.2 fixes a bug in the hit/miss animator under full or N-way set associative. It was
animating the block of initial access (first block of set). Now it animates the block
of final access (where address found or stored). Also added log display to GUI (previously System.out).

Class ScreenMagnifier

java.lang.Object
mars.tools.ScreenMagnifier

All Implemented Interfaces:
MarsTool

public class ScreenMagnifier
extends Object
implements MarsTool

Handy little tool to magnify a selected section of the screen
by a given scale and display it. The screen image snapshot
will be of the screen pixels beneath the tool’s frame. The
scale can be adjusted. The image is displayed in the tool’s
scrollable panel. You can highlight items on the image using
the scribbler (hold down mouse button and move it on the
image). The magnification scale adjustment is on the tool’s
window, but other settings can be modified on a button-
triggered dialog. It will capture the contents of the
underlying MARS graphical user interface, but NOT the
contents of other Mars Tools frames.

Constructor Detail

MemoryReferenceVisualization

public MemoryReferenceVisualization(String title,
String heading)

Simple constructor, likely used to run a stand-alone memory reference visualizer.

Parameters:
title – String containing title for title bar
heading – String containing text for heading shown in upper part of window.

MemoryReferenceVisualization

public MemoryReferenceVisualization()

Simple constructor, likely used by the MARS Tools menu mechanism

Method Detail

main

public static void main(String[] args)

Main provided for pure stand-alone use. Recommended stand-alone use is to write a
driver program that instantiates a MemoryReferenceVisualization object then invokes its go() method.
“stand-alone” means it is not invoked from the MARS Tools menu. “Pure” means there
is no driver program to invoke the application.

getName

public String getName()

Required MarsTool method to return Tool name.

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication

Returns:
Tool name. MARS will display this in menu item.

addAsObserver

protected void addAsObserver()

Override the inherited method, which registers us as an Observer over the static data segment
(starting address 0x10010000) only. This version will register us as observer over the
the memory range as selected by the base address combo box and capacity of the visualization display
(number of visualization elements times the number of memory words each one represents).
It does so by calling the inherited 2-parameter overload of this method.
If you use the inherited GUI buttons, this
method is invoked when you click “Connect” button on MarsTool or the
“Assemble and Run” button on a Mars-based app.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

buildMainDisplayArea

protected JComponent buildMainDisplayArea()

Method that constructs the main display area. It is organized vertically
into two major components: the display configuration which an be modified
using combo boxes, and the visualization display which is updated as the
attached MIPS program executes.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

Returns:
the GUI component containing these two areas

processMIPSUpdate

protected void processMIPSUpdate(Observable memory,
AccessNotice accessNotice)

Update display when connected MIPS program accesses (data) memory.

Overrides:
processMIPSUpdate in class AbstractMarsToolAndApplication

Parameters:
memory – the attached memory
accessNotice – information provided by memory in MemoryAccessNotice object

initializePreGUI

protected void initializePreGUI()

Initialize all JComboBox choice structures not already initialized at declaration.
Overrides inherited method that does nothing.

Overrides:
initializePreGUI in class AbstractMarsToolAndApplication

initializePostGUI

protected void initializePostGUI()

The only post-GUI initialization is to create the initial Grid object based on the default settings
of the various combo boxes. Overrides inherited method that does nothing.

Overrides:
initializePostGUI in class AbstractMarsToolAndApplication

reset

protected void reset()

Method to reset counters and display when the Reset button selected.
Overrides inherited method that does nothing.

Overrides:
reset in class AbstractMarsToolAndApplication

updateDisplay

protected void updateDisplay()

Updates display immediately after each update (AccessNotice) is processed, after
display configuration changes as needed, and after each execution step when Mars
is running in timed mode. Overrides inherited method that does nothing.

Overrides:
updateDisplay in class AbstractMarsToolAndApplication

getHelpComponent

protected JComponent getHelpComponent()

Overrides default method, to provide a Help button for this tool/app.

Overrides:
getHelpComponent in class AbstractMarsToolAndApplication

All Known Implementing Classes:
AbstractMarsToolAndApplication, BHTSimulator, BitmapDisplay, CacheSimulator, DigitalLabSim, FloatRepresentation, InstructionCounter, InstructionStatistics, IntroToTools, KeyboardAndDisplaySimulator, MarsBot, MemoryReferenceVisualization, ScavengerHunt, ScreenMagnifier

public interface MarsTool

Interface for any tool that interacts with an executing MIPS program.
A qualifying tool must be a class in the Tools package that
implements the MarsTool interface, must be compiled into a .class file,
and its .class file must be in the same Tools folder as MarsTool.class.
Mars will detect a qualifying tool upon startup, create an instance
using its no-argument constructor and add it to its Tools menu.
When its menu item is selected, the action() method will be invoked.

A tool may receive communication from MIPS system resources
(registers or memory) by registering as an Observer with
Mars.Memory and/or Mars.Register objects.

It may also
communicate directly with those resources through their
published methods PROVIDED any such communication is
wrapped inside a block synchronized on the
Mars.Globals.memoryAndRegistersLock object.

Method Summary

 void action()

          Performs tool functions.

 String getName()

          Return a name you have chosen for this tool.

 

Method Detail

getName

String getName()

Return a name you have chosen for this tool. It will appear as the
menu item.

action

void action()

Performs tool functions. It will be invoked when the tool is selected
from the Tools menu.

mars.tools

Class BHTableModel

java.lang.Object
javax.swing.table.AbstractTableModel
mars.tools.BHTableModel

All Implemented Interfaces:
Serializable, TableModel

public class BHTableModel
extends AbstractTableModel

Simulates the actual functionality of a Branch History Table (BHT).

The BHT consists of a number of BHT entries which are used to perform branch prediction.
The entries of the BHT are stored as a Vector of BHTEntry objects.
The number of entries is configurable but has to be a power of 2.
The history kept by each BHT entry is also configurable during run-time.
A change of the configuration however causes a complete reset of the BHT.

The typical interaction is as follows:

Construction of a BHT with a certain number of entries with a given history size.
When encountering a branch instruction the index of the relevant BHT entry is calculated via the getIdxForAddress(int) method.
The current prediction of the BHT entry at the calculated index is obtained via the getPredictionAtIdx(int) method.
After detecting if the branch was really taken or not, this feedback is provided to the BHT by the updatePredictionAtIdx(int, boolean) method.

Additionally it serves as TableModel that can be directly used to render the state of the BHT in a JTable.
Feedback provided to the BHT causes a change of the internal state and a repaint of the table(s) associated to this model.

public abstract class AbstractMarsToolAndApplication
extends JFrame
implements MarsTool, Observer

An abstract class that provides generic components to facilitate implementation of
a MarsTool and/or stand-alone Mars-based application. Provides default definitions
of both the action() method required to implement MarsTool and the go() method
conventionally used to launch a Mars-based stand-alone application. It also provides
generic definitions for interactively controlling the application. The generic controls
for MarsTools are 3 buttons: connect/disconnect to MIPS resource (memory and/or
registers), reset, and close (exit). The generic controls for stand-alone Mars apps
include: button that triggers a file open dialog, a text field to display status
messages, the run-speed slider to control execution rate when running a MIPS program,
a button that assembles and runs the current MIPS program, a button to interrupt
the running MIPS program, a reset button, and an exit button.

protected AbstractMarsToolAndApplication(String title,
String heading)

Simple constructor

Parameters:
title – String containing title bar text

Method Detail

getName

public abstract String getName()

Required MarsTool method to return Tool name. Must be defined by subclass.

Specified by:
getName in interface MarsTool
Overrides:
getName in class Component

Returns:
Tool name. MARS will display this in menu item.

buildMainDisplayArea

protected abstract JComponent buildMainDisplayArea()

Abstract method that must be instantiated by subclass to build the main display area
of the GUI. It will be placed in the CENTER area of a BorderLayout. The title
is in the NORTH area, and the controls are in the SOUTH area.

go

public void go()

Run the simulator as stand-alone application. For this default implementation,
the user-defined main display of the user interface is identical for both stand-alone
and MARS Tools menu use, but the control buttons are different because the stand-alone
must include a mechansim for controlling the opening, assembling, and executing of
an underlying MIPS program. The generic controls include: a button that triggers a
file open dialog, a text field to display status messages, the run-speed slider
to control execution rate when running a MIPS program, a button that assembles and
runs the current MIPS program, a reset button, and an exit button.
This method calls 3 methods that can be defined/overriden in the subclass: initializePreGUI()
for any special initialization that must be completed before building the user
interface (e.g. data structures whose properties determine default GUI settings),
initializePostGUI() for any special initialization that cannot be
completed until after the building the user interface (e.g. data structure whose
properties are determined by default GUI settings), and buildMainDisplayArea()
to contain application-specific displays of parameters and results.

action

public void action()

Required MarsTool method to carry out Tool functions. It is invoked when MARS
user selects this tool from the Tools menu. This default implementation provides
generic definitions for interactively controlling the tool. The generic controls
for MarsTools are 3 buttons: connect/disconnect to MIPS resource (memory and/or
registers), reset, and close (exit). Like “go()” above, this default version
calls 3 methods that can be defined/overriden in the subclass: initializePreGUI()
for any special initialization that must be completed before building the user
interface (e.g. data structures whose properties determine default GUI settings),
initializePostGUI() for any special initialization that cannot be
completed until after the building the user interface (e.g. data structure whose
properties are determined by default GUI settings), and buildMainDisplayArea()
to contain application-specific displays of parameters and results.

Specified by:
action in interface MarsTool

initializePreGUI

protected void initializePreGUI()

Method that will be called once just before the GUI is constructed in the go() and action()
methods. Use it to initialize any data structures needed for the application whose values
will be needed to determine the initial state of GUI components. By default it does nothing.

initializePostGUI

protected void initializePostGUI()

Method that will be called once just after the GUI is constructed in the go() and action()
methods. Use it to initialize data structures needed for the application whose values
may depend on the initial state of GUI components. By default it does nothing.

reset

protected void reset()

Method that will be called each time the default Reset button is clicked.
Use it to reset any data structures and/or GUI components. By default it does nothing.

buildHeadingArea

protected JComponent buildHeadingArea()

Constructs GUI header as label with default positioning and font. May be overridden.

buildButtonAreaMarsTool

protected JComponent buildButtonAreaMarsTool()

The MarsTool default set of controls has one row of 3 buttons. It includes a dual-purpose button to
attach or detach simulator to MIPS memory, a button to reset the cache, and one to close the tool.

buildButtonAreaStandAlone

protected JComponent buildButtonAreaStandAlone()

The Mars stand-alone app default set of controls has two rows of controls. It includes a text field for
displaying status messages, a button to trigger an open file dialog, the MARS run speed slider
to control timed execution, a button to assemble and run the program, a reset button
whose action is determined by the subclass reset() method, and an exit button.

update

public void update(Observable resource,
Object accessNotice)

Called when receiving notice of access to MIPS memory or registers. Default
implementation of method required by Observer interface. This method will filter out
notices originating from the MARS GUI or from direct user editing of memory or register
displays. Only notices arising from MIPS program access are allowed in.
It then calls two methods to be overridden by the subclass (since they do
nothing by default): processMIPSUpdate() then updateDisplay().

Specified by:
update in interface Observer

Parameters:
resource – the attached MIPS resource
accessNotice – AccessNotice information provided by the resource

processMIPSUpdate

protected void processMIPSUpdate(Observable resource,
AccessNotice notice)

Override this method to process a received notice from MIPS Observable (memory or register)
It will only be called if the notice was generated as the result of MIPS instruction execution.
By default it does nothing. After this method is complete, the updateDisplay() method will be
invoked automatically.

performSpecialClosingDuties

protected void performSpecialClosingDuties()

This method is called when tool/app is exited either through the close/exit button or the window’s X box.
Override it to perform any special housecleaning needed. By default it does nothing.

addAsObserver

protected void addAsObserver()

Add this app/tool as an Observer of desired MIPS Observables (memory and registers).
By default, will add as an Observer of the entire Data Segment in memory.
Override if you want something different. Note that the Memory methods to add an
Observer to memory are flexible (you can register for a range of addresses) but
may throw an AddressErrorException that you need to catch.
This method is called whenever the default “Connect” button on a MarsTool or the
default “Assemble and run” on a stand-alone Mars app is selected. The corresponding
NOTE: if you do not want to register as an Observer of the entire data segment
(starts at address 0x10000000) then override this to either do some alternative
or nothing at all. This method is also overloaded to allow arbitrary memory
subrange.

addAsObserver

protected void addAsObserver(int lowEnd,
int highEnd)

Add this app/tool as an Observer of the specified subrange of MIPS memory. Note
that this method is not invoked automatically like the no-argument version, but
if you use this method, you can still take advantage of provided default deleteAsObserver()
since it will remove the app as a memory observer regardless of the subrange
or number of subranges it is registered for.

Parameters:
lowEnd – low end of memory address range.
highEnd – high end of memory address range; must be >= lowEnd

addAsObserver

protected void addAsObserver(Register reg)

Add this app/tool as an Observer of the specified MIPS register.

deleteAsObserver

protected void deleteAsObserver()

Delete this app/tool as an Observer of MIPS Observables (memory and registers).
By default, will delete as an Observer of memory.
Override if you want something different.
This method is called when the default “Disconnect” button on a MarsTool is selected or
when the MIPS program execution triggered by the default “Assemble and run” on a stand-alone
Mars app terminates (e.g. when the button is re-enabled).

deleteAsObserver

protected void deleteAsObserver(Register reg)

Delete this app/tool as an Observer of the specified MIPS register

isObserving

protected boolean isObserving()

Query method to let you know if the tool/app is (or could be) currently
“observing” any MIPS resources. When running as a MarsTool, this
will be true by default after clicking the “Connect to MIPS” button until “Disconnect
from MIPS” is clicked. When running as a stand-alone app, this will be
true by default after clicking the “Assemble and Run” button until until
program execution has terminated either normally or by clicking the “Stop”
button. The phrase “or could be” was added above because depending on how
the tool/app operates, it may be possible to run the MIPS program without
first registering as an Observer — i.e. addAsObserver() is overridden and
takes no action.

Returns:
true if tool/app is (or could be) currently active as an Observer.

updateDisplay

protected void updateDisplay()

Override this method to implement updating of GUI after each MIPS instruction is executed,
while running in “timed” mode (user specifies execution speed on the slider control).
Does nothing by default.

getHelpComponent

protected JComponent getHelpComponent()

Override this method to provide a JComponent (probably a JButton) of your choice
to be placed just left of the Close/Exit button. Its anticipated use is for a
“help” button that launches a help message or dialog. But it can be any valid
JComponent that doesn’t mind co-existing among a bunch of JButtons.

mars.tools

Class BHTEntry

java.lang.Object
mars.tools.BHTEntry

public class BHTEntry
extends Object

Represents a single entry of the Branch History Table.

The entry holds the information about former branch predictions and outcomes.
The number of past branch outcomes can be configured and is called the history.
The semantics of the history of size n is as follows.
The entry will change its prediction, if it mispredicts the branch n times in series.
The prediction of the entry can be obtained by the getPrediction() method.
Feedback of taken or not taken branches is provided to the entry via the updatePrediction(boolean) method.
This causes the history and the prediction to be updated.

Additionally the entry keeps track about how many times the prediction was correct or incorrect.
The statistics can be obtained by the methods getStatsPredCorrect(), getStatsPredIncorrect() and getStatsPredPrecision().

Author:

Main provided for pure stand-alone use. Recommended stand-alone use is to write a
driver program that instantiates a Bitmap object then invokes its go() method.
“stand-alone” means it is not invoked from the MARS Tools menu. “Pure” means there
is no driver program to invoke the application.

getName

public String getName()

Required MarsTool method to return Tool name.

Specified by:
getName in interface MarsTool
Specified by:
getName in class AbstractMarsToolAndApplication

Returns:
Tool name. MARS will display this in menu item.

addAsObserver

protected void addAsObserver()

Override the inherited method, which registers us as an Observer over the static data segment
(starting address 0x10010000) only. This version will register us as observer over the
the memory range as selected by the base address combo box and capacity of the visualization display
(number of visualization elements times the number of memory words each one represents).
It does so by calling the inherited 2-parameter overload of this method.
If you use the inherited GUI buttons, this
method is invoked when you click “Connect” button on MarsTool or the
“Assemble and Run” button on a Mars-based app.

Overrides:
addAsObserver in class AbstractMarsToolAndApplication

buildMainDisplayArea

protected JComponent buildMainDisplayArea()

Method that constructs the main display area. It is organized vertically
into two major components: the display configuration which an be modified
using combo boxes, and the visualization display which is updated as the
attached MIPS program executes.

Specified by:
buildMainDisplayArea in class AbstractMarsToolAndApplication

Returns:
the GUI component containing these two areas

processMIPSUpdate

protected void processMIPSUpdate(Observable memory,
AccessNotice accessNotice)

Update display when connected MIPS program accesses (data) memory.

Overrides:
processMIPSUpdate in class AbstractMarsToolAndApplication

Parameters:
memory – the attached memory
accessNotice – information provided by memory in MemoryAccessNotice object

initializePreGUI

protected void initializePreGUI()

Initialize all JComboBox choice structures not already initialized at declaration.
Overrides inherited method that does nothing.

Overrides:
initializePreGUI in class AbstractMarsToolAndApplication

initializePostGUI

protected void initializePostGUI()

The only post-GUI initialization is to create the initial Grid object based on the default settings
of the various combo boxes. Overrides inherited method that does nothing.

Overrides:
initializePostGUI in class AbstractMarsToolAndApplication

reset

protected void reset()

Method to reset counters and display when the Reset button selected.
Overrides inherited method that does nothing.

Overrides:
reset in class AbstractMarsToolAndApplication

updateDisplay

protected void updateDisplay()

Updates display immediately after each update (AccessNotice) is processed, after
display configuration changes as needed, and after each execution step when Mars
is running in timed mode. Overrides inherited method that does nothing.

Overrides:
updateDisplay in class AbstractMarsToolAndApplication

getHelpComponent

protected JComponent getHelpComponent()

Overrides default method, to provide a Help button for this tool/app.

Overrides:
getHelpComponent in class AbstractMarsToolAndApplication

mars.assembler

Class Tokenizer

java.lang.Object
mars.assembler.Tokenizer

public class Tokenizer
extends Object

A tokenizer is capable of tokenizing a complete MIPS program, or a given line from
a MIPS program. Since MIPS is line-oriented, each line defines a complete statement.
Tokenizing is the process of analyzing the input MIPS program for the purpose of
recognizing each MIPS language element. The types of language elements are known as “tokens”.
MIPS tokens are defined in the TokenTypes class.

Example:

The MIPS statement here: lw $t3, 8($t4) #load third member of array

generates the following token list

IDENTIFIER, COLON, OPERATOR, REGISTER_NAME, COMMA, INTEGER_5, LEFT_PAREN,
REGISTER_NAME, RIGHT_PAREN, COMMENT

getLengthInBytes

public static int getLengthInBytes(Directives direct)

Get length in bytes for numeric MIPS directives.

Parameters:
direct – Directive to be measured.

Returns:
Returns length in bytes for values of that type. If type is not numeric
(or not implemented yet), returns 0.

outOfRange

public static boolean outOfRange(Directives direct,
int value)

Determines whether given integer value falls within value range for given directive.

Parameters:
direct – Directive that controls storage allocation for value.
value – The value to be stored.

Returns:
Returns true if value can be stored in the number of bytes allowed
by the given directive (.word, .half, .byte), false otherwise.

outOfRange

public static boolean outOfRange(Directives direct,
double value)

Determines whether given floating point value falls within value range for given directive.
For float, this refers to range of the data type, not precision. Example: 1.23456789012345
be stored in a float with loss of precision. It’s within the range. But 1.23e500 cannot be
stored in a float because the exponent 500 is too large (float allows 8 bits for exponent).

Parameters:
direct – Directive that controls storage allocation for value.
value – The value to be stored.

Returns:
Returns true if value is within range of
the given directive (.float, .double), false otherwise.

Constructor Detail

FilenameFinder

public FilenameFinder()

Method Detail

getFilenameList

public static ArrayList getFilenameList(ClassLoader classLoader,
String directoryPath,
String fileExtension)

Locate files and return list of file names. Given a known relative directory path,
it will locate it and build list of all names of files in that directory
having the given file extension. If the “known file path” doesn’t work
because MARS is running from an executable JAR file, it will locate the
directory in the JAR file and proceed from there. NOTE: since this uses
the class loader to get the resource, the directory path needs to be
relative to classpath, not absolute. To work with an arbitrary file system,
use the other version of this overloaded method. Will NOT match directories
that happen to have the desired extension.

Parameters:
classLoader – class loader to use
directoryPath – Search will be confined to this directory. Use “/” as
separator but do NOT include starting or ending “/” (e.g. mars/tools)
fileExtension – Only files with this extension will be added
to the list. Do NOT include the “.” in extension.

Returns:
array list of matching file names as Strings. If none, list is empty.

getFilenameList

Constructor Detail

TextSegmentWindow

public TextSegmentWindow()

Constructor, sets up a new JInternalFrame.

Method Detail

setupTable

public void setupTable()

Method to be called once the user compiles the program.
Should convert the lines of code over to the table rows and columns.

getProgramArguments

public String getProgramArguments()

Get program arguments from text field in south border of text segment window.

Returns:
String containing program arguments

addProgramArgumentsPanel

public void addProgramArgumentsPanel()

removeProgramArgumentsPanel

public void removeProgramArgumentsPanel()

clearWindow

public void clearWindow()

remove all components

registerTableModelListener

public void registerTableModelListener(TableModelListener tml)

Assign listener to Table model. Used for breakpoints, since that is the only editable
column in the table. Since table model objects are transient (get a new one with each
successful assemble), this method will simply keep the identity of the listener then
add it as a listener each time a new table model object is created. Limit 1 listener.

updateCodeAddresses

public void updateCodeAddresses()

Redisplay the addresses. This should only be done when address display base is
modified (e.g. between base 16 hex and base 10 dec).

updateBasicStatements

public void updateBasicStatements()

Redisplay the basic statements. This should only be done when address or value display base is
modified (e.g. between base 16 hex and base 10 dec).

update

public void update(Observable observable,
Object obj)

Required by Observer interface. Called when notified by an Observable that we are registered with.
The Observable here is a delegate of the Memory object, which lets us know of memory operations.
More precisely, memory operations only in the text segment, since that is the only range of
addresses we’re registered for. And we’re only interested in write operations.

Specified by:
update in interface Observer

Parameters:
observable – The Observable object who is notifying us
obj – Auxiliary object with additional information.

getBreakpointCount

public int getBreakpointCount()

Returns number of breakpoints currently set.

Returns:
number of current breakpoints

getSortedBreakPointsArray

public int[] getSortedBreakPointsArray()

Returns array of current breakpoints, each represented by a MIPS program counter address.
These are stored in the BREAK_COLUMN of the table model.

Returns:
int array of breakpoints, sorted by PC address, or null if there are none.

clearAllBreakpoints

public void clearAllBreakpoints()

Clears all breakpoints that have been set since last assemble, and
updates the display of the breakpoint column.

highlightStepAtPC

public void highlightStepAtPC()

Highlights the source code line whose address matches the current
program counter value. This is used for stepping through code
execution and when reaching breakpoints.

highlightStepAtPC

public void highlightStepAtPC(boolean inDelaySlot)

Highlights the source code line whose address matches the current
program counter value. This is used for stepping through code
execution and when reaching breakpoints.

Parameters:
inDelaySlot – Set true if delayed branching is enabled and the
instruction at this address is executing in the delay slot, false
otherwise.

highlightStepAtAddress

public void highlightStepAtAddress(int address)

Highlights the source code line whose address matches the given
text segment address.

Parameters:
address – text segment address of instruction to be highlighted.

highlightStepAtAddress

public void highlightStepAtAddress(int address,
boolean inDelaySlot)

Highlights the source code line whose address matches the given
text segment address.

Parameters:
address – Text segment address of instruction to be highlighted.
inDelaySlot – Set true if delayed branching is enabled and the
instruction at this address is executing in the delay slot, false
otherwise.

setCodeHighlighting

public void setCodeHighlighting(boolean highlightSetting)

Used to enable or disable source code highlighting. If true (normally while
stepping through execution) then MIPS statement at current program counter
is highlighted. The code column’s cell renderer tests this variable.

Parameters:
highlightSetting – true to enable highlighting, false to disable.

getCodeHighlighting

public boolean getCodeHighlighting()

Get code highlighting status.

Returns:
true if code highlighting currently enabled, false otherwise.

unhighlightAllSteps

public void unhighlightAllSteps()

If any steps are highlighted, this erases the highlighting.

toggleBreakpoints

public void toggleBreakpoints()

Enable or disable all items in the Breakpoints column.

Class KeywordMap

java.lang.Object
mars.venus.editors.jeditsyntax.KeywordMap

public class KeywordMap
extends Object

A KeywordMap is similar to a hashtable in that it maps keys
to values. However, the `keys’ are Swing segments. This allows lookups of
text substrings without the overhead of creating a new string object.

This class is used by CTokenMarker to map keywords to ids.

javax.swing.JComponent
mars.venus.editors.jeditsyntax.JEditTextArea

All Implemented Interfaces:
ImageObserver, MenuContainer, Serializable

Direct Known Subclasses:
JEditBasedTextArea

public class JEditTextArea
extends JComponent

jEdit’s text area component. It is more suited for editing program
source code than JEditorPane, because it drops the unnecessary features
(images, variable-width lines, and so on) and adds a whole bunch of
useful goodies such as:

More flexible key binding scheme

Supports macro recorders

Rectangular selection

Bracket highlighting

Syntax highlighting

Command repetition

Block caret can be enabled

It is also faster and doesn’t have as many problems. It can be used
in other applications; the only other part of jEdit it depends on is
the syntax package.

To use it in your app, treat it like any other component, for example:

JEditTextArea ta = new JEditTextArea();
ta.setTokenMarker(new JavaTokenMarker());
ta.setText(“public class Test {\n”
+ ” public static void main(String[] args) {\n”
+ ” System.out.println(\”Hello World\”);\n”
+ ” }\n”
+ “}”);

mars.venus.editors.jeditsyntax.tokenmarker

Class TokenMarker

java.lang.Object
mars.venus.editors.jeditsyntax.tokenmarker.TokenMarker

Direct Known Subclasses:
MIPSTokenMarker

public abstract class TokenMarker
extends Object

A token marker that splits lines of text into tokens. Each token carries
a length field and an indentification tag that can be mapped to a color
for painting that token.

For performance reasons, the linked list of tokens is reused after each
line is tokenized. Therefore, the return value of markTokens
should only be used for immediate painting. Notably, it cannot be
cached.

Field Detail

firstToken

protected Token firstToken

The first token in the list. This should be used as the return
value from markTokens().

lastToken

protected Token lastToken

The last token in the list. New tokens are added here.
This should be set to null before a new line is to be tokenized.

lineInfo

protected TokenMarker.LineInfo[] lineInfo

An array for storing information about lines. It is enlarged and
shrunk automatically by the insertLines() and
deleteLines() methods.

length

protected int length

The number of lines in the model being tokenized. This can be
less than the length of the lineInfo array.

lastLine

protected int lastLine

The last tokenized line.

nextLineRequested

protected boolean nextLineRequested

True if the next line should be painted.

Constructor Detail

TokenMarker

protected TokenMarker()

Creates a new TokenMarker. This DOES NOT create
a lineInfo array; an initial call to insertLines()
does that.

Method Detail

markTokens

public Token markTokens(Segment line,
int lineIndex)

A wrapper for the lower-level markTokensImpl method
that is called to split a line up into tokens.

Parameters:
line – The line
lineIndex – The line number

markTokensImpl

protected abstract byte markTokensImpl(byte token,
Segment line,
int lineIndex)

An abstract method that splits a line up into tokens. It
should parse the line, and call addToken() to
add syntax tokens to the token list. Then, it should return
the initial token type for the next line.

For example if the current line contains the start of a
multiline comment that doesn’t end on that line, this method
should return the comment token type so that it continues on
the next line.

Parameters:
token – The initial token type for this line
line – The line to be tokenized
lineIndex – The index of the line in the document, starting at 0

Returns:
The initial token type for the next line

supportsMultilineTokens

public boolean supportsMultilineTokens()

Returns if the token marker supports tokens that span multiple
lines. If this is true, the object using this token marker is
required to pass all lines in the document to the
markTokens() method (in turn).

The default implementation returns true; it should be overridden
to return false on simpler token markers for increased speed.

insertLines

public void insertLines(int index,
int lines)

Informs the token marker that lines have been inserted into
the document. This inserts a gap in the lineInfo
array.

Parameters:
index – The first line number
lines – The number of lines

deleteLines

public void deleteLines(int index,
int lines)

Informs the token marker that line have been deleted from
the document. This removes the lines in question from the
lineInfo array.

Parameters:
index – The first line number
lines – The number of lines

getLineCount

public int getLineCount()

Returns the number of lines in this token marker.

isNextLineRequested

public boolean isNextLineRequested()

Returns true if the next line should be repainted. This
will return true after a line has been tokenized that starts
a multiline token that continues onto the next line.

getTokenExactMatchHelp

public ArrayList getTokenExactMatchHelp(Token token,
String tokenText)

Construct and return any appropriate help information for
the given token. This default definition returns null;
override it in language-specific subclasses.

Parameters:
token – the pertinent Token object
tokenText – the source String that matched to the token

Returns:
ArrayList containing PopupHelpItem objects, one per match.

getTokenPrefixMatchHelp

public ArrayList getTokenPrefixMatchHelp(String line,
Token tokenList,
Token tokenAtOffset,
String tokenText)

Construct and return any appropriate help information for
the given token or “token prefix”. Will match instruction prefixes, e.g. “s” matches “sw”.
This default definition returns null;
override it in language-specific subclasses.

Parameters:
line – String containing current line
tokenList – first Token on the current line
token – the pertinent Token object
tokenText – the source String that matched to the token

Returns:
ArrayList containing PopupHelpItem objects, one per match.

ensureCapacity

protected void ensureCapacity(int index)

Ensures that the lineInfo array can contain the
specified index. This enlarges it if necessary. No action is
taken if the array is large enough already.

It should be unnecessary to call this under normal
circumstances; insertLine() should take care of
enlarging the line info array automatically.

Parameters:
index – The array index

addToken

protected void addToken(int length,
byte id)

Adds a token to the token list.

Parameters:
length – The length of the token
id – The id of the token

markTokensImpl

public byte markTokensImpl(byte token,
Segment line,
int lineIndex)

Description copied from class: TokenMarker
An abstract method that splits a line up into tokens. It
should parse the line, and call addToken() to
add syntax tokens to the token list. Then, it should return
the initial token type for the next line.

For example if the current line contains the start of a
multiline comment that doesn’t end on that line, this method
should return the comment token type so that it continues on
the next line.

Specified by:
markTokensImpl in class TokenMarker

Parameters:
token – The initial token type for this line
line – The line to be tokenized
lineIndex – The index of the line in the document, starting at 0

Returns:
The initial token type for the next line

getTokenExactMatchHelp

public ArrayList getTokenExactMatchHelp(Token token,
String tokenText)

Construct and return any appropriate help information for
the given token.

Overrides:
getTokenExactMatchHelp in class TokenMarker

Parameters:
token – the pertinent Token object
tokenText – the source String that matched to the token

Returns:
ArrayList of PopupHelpItem objects, one per match.

getTokenPrefixMatchHelp

public ArrayList getTokenPrefixMatchHelp(String line,
Token tokenList,
Token token,
String tokenText)

Construct and return any appropriate help information for
prefix match based on current line’s token list.

Overrides:
getTokenPrefixMatchHelp in class TokenMarker

Parameters:
line – String containing current line
tokenList – first Token on current line (head of linked list)
token – the pertinent Token object
tokenText – the source String that matched to the token in previous parameter

Returns:
ArrayList of PopupHelpItem objects, one per match.

getKeywords

public static KeywordMap getKeywords()

Get KeywordMap containing all MIPS key words. This includes all instruction mnemonics,
assembler directives, and register names.

Returns:
KeywordMap where key is the keyword and associated value is the token type (e.g. Token.KEYWORD1).

mars.venus.editors.jeditsyntax.InputHandler

All Implemented Interfaces:
KeyListener, EventListener

Direct Known Subclasses:
DefaultInputHandler

public abstract class InputHandler
extends KeyAdapter

An input handler converts the user’s key strokes into concrete actions.
It also takes care of macro recording and action repetition.

This class provides all the necessary support code for an input
handler, but doesn’t actually do any key binding logic. It is up
to the implementations of this class to do so.

public class SettingsDelayedBranchingAction
extends GuiAction

Action class for the Settings menu item to control delayed branching.
Note: Changing this setting while the current program is runnable
(assembled, or stepped execution) or terminated triggers a re-assembly.
This is necessary to maintain consistency because the machine
code assembled for branch instructions differs depending on
this setting — would branch to incorrect address if setting
were changed between assembly and execution.
Note: This action is disabled while the MIPS program is running.
The user need only pause or stop execution to re-enable it.

Constructor Detail

ExecutePane

public ExecutePane(VenusUI mainUI,
RegistersWindow regs,
Coprocessor1Window cop1Regs,
Coprocessor0Window cop0Regs)

initialize the Execute pane with major components

Parameters:
mainUI – the parent GUI
regs – window containing integer register set
cop1Regs – window containing Coprocessor 1 register set
cop0Regs – window containing Coprocessor 0 register set

Method Detail

setWindowBounds

public void setWindowBounds()

This method will set the bounds of this JDesktopPane’s internal windows
relative to the current size of this JDesktopPane. Such an operation
cannot be adequately done at constructor time because the actual
size of the desktop pane window is not yet established. Layout manager
is not a good option here because JDesktopPane does not work well with
them (the whole idea of using JDesktopPane with internal frames is to
have mini-frames that you can resize, move around, minimize, etc). This
method should be invoked only once: the first time the Execute tab is
selected (a change listener invokes it). We do not want it invoked
on subsequent tab selections; otherwise, user manipulations of the
internal frames would be lost the next time execute tab is selected.

setLabelWindowVisibility

public void setLabelWindowVisibility(boolean visibility)

Show or hide the label window (symbol table). If visible, it is displayed
to the right of the text segment and the latter is shrunk accordingly.

Parameters:
visibility – set to true or false

clearPane

public void clearPane()

Clears out all components of the Execute tab: text segment
display, data segment display, label display and register display.
This will typically be done upon File->Close, Open, New.

getTextSegmentWindow

public TextSegmentWindow getTextSegmentWindow()

Access the text segment window.

getDataSegmentWindow

public DataSegmentWindow getDataSegmentWindow()

Access the data segment window.

getRegistersWindow

public RegistersWindow getRegistersWindow()

Access the register values window.

getCoprocessor1Window

public Coprocessor1Window getCoprocessor1Window()

Access the coprocessor1 values window.

getCoprocessor0Window

public Coprocessor0Window getCoprocessor0Window()

Access the coprocessor0 values window.

getLabelsWindow

public LabelsWindow getLabelsWindow()

Access the label values window.

getValueDisplayBase

public int getValueDisplayBase()

Retrieve the number system base for displaying values (mem/register contents)

getAddressDisplayBase

public int getAddressDisplayBase()

Retrieve the number system base for displaying memory addresses

getValueDisplayBaseChooser

public NumberDisplayBaseChooser getValueDisplayBaseChooser()

Retrieve component used to set numerical base (10 or 16) of data value display.

Returns:
the chooser

getAddressDisplayBaseChooser

public NumberDisplayBaseChooser getAddressDisplayBaseChooser()

Retrieve component used to set numerical base (10 or 16) of address display.

Returns:
the chooser

numberDisplayBaseChanged

public void numberDisplayBaseChanged(NumberDisplayBaseChooser chooser)

Update display of columns based on state of given chooser. Normally
called only by the chooser’s ItemListener.

Parameters:
chooser – the GUI object manipulated by the user to change number base

Constructor Detail

RunClearBreakpointsAction

public RunClearBreakpointsAction(String name,
Icon icon,
String descrip,
Integer mnemonic,
KeyStroke accel,
VenusUI gui)

Create the object and register with text segment window as a listener on its table model.
The table model has not been created yet, so text segment window will hang onto this
registration info and transfer it to the table model upon creation (which happens with
each successful assembly).

Method Detail

actionPerformed

public void actionPerformed(ActionEvent e)

When this option is selected, tell text segment window to clear breakpoints in its table model.

Specified by:
actionPerformed in interface ActionListener
Overrides:
actionPerformed in class GuiAction

tableChanged

public void tableChanged(TableModelEvent e)

Required TableModelListener method. This is response upon editing of text segment table
model. The only editable column is breakpoints so this method is called only when user
adds or removes a breakpoint. Gets new breakpoint count and sets enabled status
accordingly.

Specified by:
tableChanged in interface TableModelListener

Class RepeatButton

java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.AbstractButton
javax.swing.JButton
mars.venus.RepeatButton

All Implemented Interfaces:
ActionListener, MouseListener, ImageObserver, ItemSelectable, MenuContainer, Serializable, EventListener, Accessible, SwingConstants

public class RepeatButton
extends JButton
implements ActionListener, MouseListener

RepeatButton is a JButton which contains a timer
for firing events while the button is held down. There is a default
initial delay of 300ms before the first event is fired and a 60ms delay
between subsequent events. When the user holds the button down and moves
the mouse out from over the button, the timer stops, but if the user moves
the mouse back over the button without having released the mouse button,
the timer starts up again at the same delay rate. If the enabled state is
changed while the timer is active, it will be stopped.

NOTE: The normal button behavior is that the action event is fired after
the button is released. It may be important to konw then that this is
still the case. So in effect, listeners will get 1 more event then what
the internal timer fires. It’s not a “bug”, per se, just something to be
aware of. There seems to be no way to suppress the final event from
firing anyway, except to process all ActionListeners internally. But
realistically, it probably doesn’t matter.

MessagesPane

public MessagesPane()

Constructor for the class, sets up two fresh tabbed text areas for program feedback.

Method Detail

selectErrorMessage

public void selectErrorMessage(String fileName,
int line,
int column)

Will select the Mars Messages tab error message that matches the given
specifications, if it is found. Matching is done by constructing
a string using the parameter values and searching the text area for the last
occurrance of that string.

Parameters:
fileName – A String containing the file path name.
line – Line number for error message
column – Column number for error message

selectEditorTextLine

public void selectEditorTextLine(String fileName,
int line,
int column)

Will select the specified line in an editor tab. If the file is open
but not current, its tab will be made current. If the file is not open,
it will be opened in a new tab and made current, however the line will
not be selected (apparent apparent problem with JEditTextArea).

Parameters:
fileName – A String containing the file path name.
line – Line number for error message
column – Column number for error message

getAssembleTextArea

public JTextArea getAssembleTextArea()

Returns component used to display assembler messages

Returns:
assembler message text component

getRunTextArea

public JTextArea getRunTextArea()

Returns component used to display runtime messages

Returns:
runtime message text component

postMarsMessage

public void postMarsMessage(String message)

Post a message to the assembler display

Parameters:
message – String to append to assembler display text

postRunMessage

public void postRunMessage(String message)

Post a message to the runtime display

Parameters:
message – String to append to runtime display text

selectMarsMessageTab

public void selectMarsMessageTab()

Make the assembler message tab current (up front)

selectRunMessageTab

public void selectRunMessageTab()

Make the runtime message tab current (up front)

getInputString

public String getInputString(String prompt)

Method used by the SystemIO class to get interactive user input
requested by a running MIPS program (e.g. syscall #5 to read an
integer). SystemIO knows whether simulator is being run at
command line by the user, or by the GUI. If run at command line,
it gets input from System.in rather than here.

This is an overloaded method. This version, with the String parameter,
is used to get input from a popup dialog.

Parameters:
prompt – Prompt to display to the user.

Returns:
User input.

getInputString

public String getInputString(int maxLen)

Method used by the SystemIO class to get interactive user input
requested by a running MIPS program (e.g. syscall #5 to read an
integer). SystemIO knows whether simulator is being run at
command line by the user, or by the GUI. If run at command line,
it gets input from System.in rather than here.

This is an overloaded method. This version, with the int parameter,
is used to get input from the MARS Run I/O window.

Parameters:
maxLen: – maximum length of input. This method returns when maxLen characters have been read. Use -1 for no length restrictions.

Returns:
User input.

Constructor Detail

NumberDisplayBaseChooser

public NumberDisplayBaseChooser(String text,
boolean displayInHex)

constructor. It assumes the text will be worded
so that a checked box means hexadecimal!

Parameters:
text – Text to accompany the check box.
defaultBase – Currently either DECIMAL or HEXADECIMAL

Method Detail

getBase

public int getBase()

Retrieve the current number base.

Returns:
current number base, currently DECIMAL or HEXADECIMAL

setBase

public void setBase(int newBase)

Set the current number base.

Parameters:
newBase – The new number base. Currently, if it is
neither DECIMAL nor HEXADECIMAL, the base will not be changed.

formatUnsignedInteger

public static String formatUnsignedInteger(int value,
int base)

Produces a string form of an unsigned given the value and the
numerical base to convert it to. This class
method can be used by anyone anytime. If base is 16, result
is same as for formatNumber(). If base is 10, will produce
string version of unsigned value. E.g. 0xffffffff will produce
“4294967295” instead of “-1”.

Parameters:
value – the number to be converted
base – the numerical base to use (currently 10 or 16)

Returns:
a String equivalent of the value rendered appropriately.

formatNumber

public static String formatNumber(int value,
int base)

Produces a string form of an integer given the value and the
numerical base to convert it to. There is an instance
method that uses the internally stored base. This class
method can be used by anyone anytime.

Parameters:
value – the number to be converted
base – the numerical base to use (currently 10 or 16)

Returns:
a String equivalent of the value rendered appropriately.

formatNumber

public static String formatNumber(float value,
int base)

Produces a string form of a float given the value and the
numerical base to convert it to. There is an instance
method that uses the internally stored base. This class
method can be used by anyone anytime.

Parameters:
value – the number to be converted
base – the numerical base to use (currently 10 or 16)

Returns:
a String equivalent of the value rendered appropriately.

formatNumber

public static String formatNumber(double value,
int base)

Produces a string form of a double given the value and the
numerical base to convert it to. There is an instance
method that uses the internally stored base. This class
method can be used by anyone anytime.

Parameters:
value – the number to be converted
base – the numerical base to use (currently 10 or 16)

Returns:
a String equivalent of the value rendered appropriately.

formatNumber

public String formatNumber(int value)

Produces a string form of a number given the value. There
is also an class (static method) that uses a specified
base.

Parameters:
value – the number to be converted

Returns:
a String equivalent of the value rendered appropriately.

formatUnsignedInteger

public String formatUnsignedInteger(int value)

Produces a string form of an unsigned integer given the value. There
is also an class (static method) that uses a specified base.
If the current base is 16, this produces the same result as formatNumber().

Parameters:
value – the number to be converted

Returns:
a String equivalent of the value rendered appropriately.

formatFloatNumber

public static String formatFloatNumber(int value,
int base)

Produces a string form of a float given an integer containing
the 32 bit pattern and the numerical base to use (10 or 16). If the
base is 16, the string will be built from the 32 bits. If the
base is 10, the int bits will be converted to float and the
string constructed from that. Seems an odd distinction to make,
except that contents of floating point registers are stored
internally as int bits. If the int bits represent a NaN value
(of which there are many!), converting them to float then calling
formatNumber(float, int) above, causes the float value to become
the canonical NaN value 0x7fc00000. It does not preserve the bit
pattern! Then converting it to hex string yields the canonical NaN.
Not an issue if display base is 10 since result string will be NaN
no matter what the internal NaN value is.

Parameters:
value – the int bits to be converted to string of corresponding float.
base – the numerical base to use (currently 10 or 16)

Returns:
a String equivalent of the value rendered appropriately.

formatDoubleNumber

public static String formatDoubleNumber(long value,
int base)

Produces a string form of a double given a long containing
the 64 bit pattern and the numerical base to use (10 or 16). If the
base is 16, the string will be built from the 64 bits. If the
base is 10, the long bits will be converted to double and the
string constructed from that. Seems an odd distinction to make,
except that contents of floating point registers are stored
internally as int bits. If the int bits represent a NaN value
(of which there are many!), converting them to double then calling
formatNumber(double, int) above, causes the double value to become
the canonical NaN value. It does not preserve the bit
pattern! Then converting it to hex string yields the canonical NaN.
Not an issue if display base is 10 since result string will be NaN
no matter what the internal NaN value is.

Parameters:
value – the long bits to be converted to string of corresponding double.
base – the numerical base to use (currently 10 or 16)

Returns:
a String equivalent of the value rendered appropriately.

setSettingsMenuItem

public void setSettingsMenuItem(JCheckBoxMenuItem setter)

Set the menu item from Settings menu that corresponds to this chooser.
It is the responsibility of that item to register here, because this
one is created first (before the menu item). They need to communicate
with each other so that whenever one changes, so does the other. They
cannot be the same object (one is JCheckBox, the other is JCheckBoxMenuItem).

getBase

public static int getBase(boolean setting)

Return the number base corresponding to the specified setting.

Returns:
HEXADECIMAL if setting is true, DECIMAL otherwise.

implements Observer

Represents one file opened for editing. Maintains required internal structures.
Before Mars 4.0, there was only one editor pane, a tab, and only one file could
be open at a time. With 4.0 came the multifile (pane, tab) editor, and existing
duties were split between EditPane and the new EditTabbedPane class.

Parameters:
find – the text to locate in the string
replace – the text to replace the find text with – if the find text exists
caseSensitive – true for case sensitive. false to ignore case

Returns:
Returns TEXT_FOUND if not initially at end of selected match and matching
occurrence is found. Returns TEXT_NOT_FOUND if the text is not matched.
Returns TEXT_REPLACED_NOT_FOUND_NEXT if replacement is successful but there are
no additional matches. Returns TEXT_REPLACED_FOUND_NEXT if reaplacement is
successful and there is at least one additional match.

doReplaceAll

public int doReplaceAll(String find,
String replace,
boolean caseSensitive)

Finds and replaces ALL occurrences of text in a string in a forward search.
All replacements are bundled into one CompoundEdit, so one Undo operation will
undo all of them.

Class ToolLoader

java.lang.Object
mars.venus.ToolLoader

public class ToolLoader
extends Object

This class provides functionality to bring external Mars tools into the Mars
system by adding them to its Tools menu. This permits anyone with knowledge
of the Mars public interfaces, in particular of the Memory and Register
classes, to write applications which can interact with a MIPS program
executing under Mars. The execution is of course simulated. The
private method for loading tool classes is adapted from Bret Barker’s
GameServer class from the book “Developing Games In Java”.

buildToolsMenu

public JMenu buildToolsMenu()

Called in VenusUI to build its Tools menu. If there are no qualifying tools
or any problems accessing those tools, it returns null. A qualifying tool
must be a class in the Tools package that implements MarsTool, must be compiled
into a .class file, and its .class file must be in the same Tools folder as
MarsTool.class.

Returns:
a Tools JMenu if qualifying tool classes are found, otherwise null

java.lang.Object
mars.mips.instructions.Instruction
mars.mips.instructions.ExtendedInstruction

public class ExtendedInstruction
extends Instruction

ExtendedInstruction represents a MIPS extended (a.k.a pseudo) instruction. This
assembly language instruction does not have a corresponding machine instruction. Instead
it is translated by the extended assembler into one or more basic instructions (operations
that have a corresponding machine instruction). The TranslationCode object is
responsible for performing the translation.

Constructor Detail

ExtendedInstruction

public ExtendedInstruction(String example,
String translation,
String compactTranslation,
String description)

Constructor for ExtendedInstruction.

Parameters:
example – A String containing example use of the MIPS extended instruction.
translation – Specifications for translating this instruction into a sequence
of one or more MIPS basic instructions.
compactTranslation – Alternative translation that can be used if running under
a compact (16 bit) memory configuration.
description – a helpful description to be included on help requests

The presence of an alternative “compact translation” can optimize code generation
by assuming that data label addresses are 16 bits instead of 32

ExtendedInstruction

public ExtendedInstruction(String example,
String translation,
String description)

Constructor for ExtendedInstruction. No compact translation is provided.

Parameters:
example – A String containing example use of the MIPS extended instruction.
translation – Specifications for translating this instruction into a sequence
of one or more MIPS basic instructions.
description – a helpful description to be included on help requests

ExtendedInstruction

public ExtendedInstruction(String example,
String translation)

Constructor for ExtendedInstruction, where no instruction description or
compact translation is provided.

Parameters:
example – A String containing example use of the MIPS extended instruction.
translation – Specifications for translating this instruction into a sequence
of one or more MIPS basic instructions.

Method Detail

getInstructionLength

public int getInstructionLength()

Get length in bytes that this extended instruction requires in its
binary form. The answer depends on how many basic instructions it
expands to. This may vary, if expansion includes a nop, depending on
whether or not delayed branches are enabled. Each requires 4 bytes.

Overrides:
getInstructionLength in class Instruction

Returns:
int length in bytes of corresponding binary instruction(s).

getBasicIntructionTemplateList

public ArrayList getBasicIntructionTemplateList()

Get ArrayList of Strings that represent list of templates for
basic instructions generated by this extended instruction.

Returns:
ArrayList of Strings.

getCompactInstructionLength

public int getCompactInstructionLength()

Get length in bytes that this extended instruction requires in its
binary form if it includes an alternative expansion for compact
memory (16 bit addressing) configuration. The answer depends on
how many basic instructions it expands to. This may vary, if
expansion includes a nop, depending on whether or not delayed
branches are enabled. Each requires 4 bytes.

Returns:
int length in bytes of corresponding binary instruction(s).
Returns 0 if an alternative expansion is not defined for this
instruction.

hasCompactTranslation

public boolean hasCompactTranslation()

Determine whether or not this pseudo-instruction has a second
translation optimized for 16 bit address space: a compact version.

getCompactBasicIntructionTemplateList

public ArrayList getCompactBasicIntructionTemplateList()

Get ArrayList of Strings that represent list of templates for
basic instructions generated by the “compact” or 16-bit version
of this extended instruction.

Returns:
ArrayList of Strings. Returns null if the instruction does not
have a compact alternative.

makeTemplateSubstitutions

public static String makeTemplateSubstitutions(MIPSprogram program,
String template,
TokenList theTokenList)

Given a basic instruction template and the list of tokens from an extended
instruction statement, substitute operands from the token list appropriately into the
template to generate the basic statement. Assumes the extended instruction statement has
been translated from source form to basic assembly form (e.g. register mnemonics
translated to corresponding register numbers).
Operand format of source statement is already verified correct.
Assume the template has correct number and positions of operands.
Template is String with special markers. In the list below, n represents token position (1,2,3,etc)
in source statement (operator is token 0, parentheses count but commas don’t):
RGn means substitute register found in n’th token of source statement

NRn means substitute next higher register than the one in n’th token of source code

OPn means substitute n’th token of source code as is

LLn means substitute low order 16 bits from label address in source token n.

LLnU means substitute low order 16 bits (unsigned) from label address in source token n.

LLnPm (m=1,2,3,4) means substitute low order 16 bits from label address in source token n, after adding m.

LHn means substitute high order 16 bits from label address in source token n. Must add 1 if address bit 15 is 1.

LHnPm (m=1,2,3,4) means substitute high order 16 bits from label address in source token n, after adding m. Must then add 1 if bit 15 is 1.

VLn means substitute low order 16 bits from 32 bit value in source token n.

VLnU means substitute low order 16 bits (unsigned) from 32 bit value in source token n.

VLnPm (m=1,2,3,4) means substitute low order 16 bits from 32 bit value in source token n, after adding m to value.

LLP is similar to LLn, but is needed for “label+100000” address offset. Immediate is added before taking low order 16.

LLPU is similar to LLnU, but is needed for “label+100000” address offset. Immediate is added before taking low order 16 (unsigned).

LLPPm (m=1,2,3,4) is similar to LLP except m is added along with mmediate before taking low order 16.

LHPA is similar to LHn, but is needed for “label+100000” address offset. Immediate is added before taking high order 16.

LHPN is similar to LHPA, used only by “la” instruction. Address resolved by “ori” so do not add 1 if bit 15 is 1.

LHPAPm (m=1,2,3,4) is similar to LHPA except value m is added along with immediate before taking high order 16.

LHL means substitute high order 16 bits from label address in token 2 of “la” (load address) source statement.

LAB means substitute textual label from last token of source statement. Used for various branches.

Class BasicInstructionFormat

java.lang.Object
mars.mips.instructions.BasicInstructionFormat

public class BasicInstructionFormat
extends Object

These are the MIPS-defined formats of basic machine instructions. The R-format indicates
the instruction works only with registers. The I-format indicates the instruction
works with an immediate value (e.g. constant). The J-format indicates this is a Jump
instruction. The I-branch-format is defined by me, not MIPS, to to indicate this is
a Branch instruction, specifically to distinguish immediate
values used as target addresses.

Method Detail

simulate

public void simulate(ProgramStatement statement)
throws ProcessingException

Performs syscall function to send MIDI output to sound card. This requires
four arguments in registers $a0 through $a3.

$a0 – pitch (note). Integer value from 0 to 127, with 60 being middle-C on a piano.

$a1 – duration. Integer value in milliseconds.

$a2 – instrument. Integer value from 0 to 127, with 0 being acoustic grand piano.

$a3 – volume. Integer value from 0 to 127.

Default values, in case any parameters are outside the above ranges, are $a0=60, $a1=1000,
$a2=0, $a3=100.

See MARS documentation elsewhere or www.midi.org for more information. Note that the pitch,
instrument and volume value ranges 0-127 are from javax.sound.midi; actual MIDI instruments
use the range 1-128.

Constructor Detail

SyscallOpen

public SyscallOpen()

Build an instance of the Open file syscall. Default service number
is 13 and name is “Open”.

Method Detail

simulate

public void simulate(ProgramStatement statement)
throws ProcessingException

Performs syscall function to open file name specified by $a0. File descriptor returned
in $v0. Only supported flags ($a1) are read-only (0), write-only (1) and
write-append (9). write-only flag creates file if it does not exist, so it is technically
write-create. write-append will start writing at end of existing file.
Mode ($a2) is ignored.

public abstract class AbstractSyscall
extends Object
implements Syscall

Abstract class that a MIPS syscall system service may extend. A qualifying service
must be a class in the mars.mips.instructions.syscalls package that
implements the Syscall interface, must be compiled into a .class file,
and its .class file must be in the same folder as Syscall.class.
Mars will detect a qualifying syscall upon startup, create an instance
using its no-argument constructor and add it to its syscall list.
When its service is invoked at runtime (“syscall” instruction
with its service number stored in register $v0), its simulate()
method will be invoked.

Constructor Summary
AbstractSyscall(int number,
String name)

          Constructor is provided so subclass may initialize instance variables.

 

Method Summary

 String getName()

          Return the name you have chosen for this syscall.

 int getNumber()

          Return the assigned service number.

 void setNumber(int num)

public interface Syscall

Interface for any MIPS syscall system service. A qualifying service
must be a class in the mars.mips.instructions.syscalls package that
implements the Syscall interface, must be compiled into a .class file,
and its .class file must be in the same folder as Syscall.class.
Mars will detect a qualifying syscall upon startup, create an instance
using its no-argument constructor and add it to its syscall list.
When its service is invoked at runtime (“syscall” instruction
with its service number stored in register $v0), its simulate()
method will be invoked.

Method Summary

 String getName()

          Return a name you have chosen for this syscall.

 int getNumber()

          Return the assigned service number.

 void setNumber(int num)

          Set the service number.

 void simulate(ProgramStatement statement)

          Performs syscall function.

 

Method Detail

getName

String getName()

Return a name you have chosen for this syscall. This can be used by a MARS
user to refer to the service when choosing to override its default service
number in the configuration file.

Returns:
service name as a string

setNumber

void setNumber(int num)

Set the service number. This is provided to allow MARS implementer or user
to override the default service number.

Parameters:
num – specified service number to override the default.

getNumber

int getNumber()

Return the assigned service number. This is the number the MIPS programmer
must store into $v0 before issuing the SYSCALL instruction.

Returns:
assigned service number

simulate

void simulate(ProgramStatement statement)
throws ProcessingException

Performs syscall function. It will be invoked when the service is invoked
at simulation time. Service is identified by value stored in $v0.

Parameters:
statement – ProgramStatement for this syscall statement.

Throws:

ProcessingException

is 33 and name is “MidiOutSync”.

Method Detail

simulate

public void simulate(ProgramStatement statement)
throws ProcessingException

Performs syscall function to send MIDI output to sound card. The syscall does not
return until after the duration period ($a1) has elapsed. This requires
four arguments in registers $a0 through $a3.

$a0 – pitch (note). Integer value from 0 to 127, with 60 being middle-C on a piano.

$a1 – duration. Integer value in milliseconds.

$a2 – instrument. Integer value from 0 to 127, with 0 being acoustic grand piano.

$a3 – volume. Integer value from 0 to 127.

Default values, in case any parameters are outside the above ranges, are $a0=60, $a1=1000,
$a2=0, $a3=100.

See MARS documentation elsewhere or www.midi.org for more information. Note that the pitch,
instrument and volume value ranges 0-127 are from javax.sound.midi; actual MIDI instruments
use the range 1-128.

BasicInstruction

public BasicInstruction(String example,
String description,
BasicInstructionFormat instrFormat,
String operMask,
SimulationCode simCode)

BasicInstruction constructor.

Parameters:
example – An example usage of the instruction, as a String.
instrFormat – The format is R, I, I-branch or J.
operMask – The opcode mask is a 32 character string that contains the opcode in binary in the appropriate bit positions and codes for operand positions (‘f’, ‘s’, ‘t’) in the remainding positions.
simCode – The inline definition of an object and class which anonymously implements the SimulationCode interface.
See Also:

BasicInstruction

public BasicInstruction(String example,
BasicInstructionFormat instrFormat,
String operMask,
SimulationCode simCode)

Method Detail

getOperationMask

public String getOperationMask()

Gets the 32-character operation mask. Each mask position represents a
bit position in the 32-bit machine instruction. Operation codes and
unused bits are represented in the mask by 1’s and 0’s. Operand codes
are represented by ‘f’, ‘s’, and ‘t’ for bits occupied by first, secon
and third operand, respectively.

Returns:
The 32 bit mask, as a String

getInstructionFormat

public BasicInstructionFormat getInstructionFormat()

Gets the operand format of the instruction. MIPS defines 3 of these
R-format, I-format, and J-format. R-format is all registers. I-format
is address formed from register base with immediate offset. J-format
is for jump destination addresses. I have added one more:
I-branch-format, for branch destination addresses. These are a variation
of the I-format in that the computed value is address relative to the
Program Counter. All four formats are represented by static objects.

Returns:
The machine instruction format, R, I, J or I-branch.

getSimulationCode

public SimulationCode getSimulationCode()

Gets the SimulationCode object. It is really an object of an anonymous
class that implements the SimulationCode interface. Such an object has but one
method: Simulate().

Returns:
the SimulationCode object for this instruction.

Note: the codes for External Interrupts have been modified from MIPS
specs in order to encode two pieces of information. According
to spec, there is one External Interrupt code, 0. But then
how to distinguish keyboard interrupt from display interrupt?
The Cause register has Interupt Pending bits that can be set.
Bit 8 represents keyboard, bit 9 represents display. Those
bits are included into this code, but shifted right two positions
since the interrupt code will be shifted left two positions
for inserting cause code into bit positions 2-6 in Cause register.

inDelaySlot

public static boolean inDelaySlot()

Determine whether or not the next instruction to be executed is in a
“delay slot”. This means delayed branching is enabled, the branch
condition has evaluated true, and the next instruction executed will
be the one following the branch. It is said to occupy the “delay slot.”
Normally programmers put a nop instruction here but it can be anything.

Returns:
true if next instruction is in delay slot, false otherwise.

simulate

public boolean simulate(MIPSprogram p,
int pc,

Simulate execution of given MIPS program. It must have already been assembled.

Parameters:
p – The MIPSprogram to be simulated.
pc – address of first instruction to simulate; this goes into program counter
maxSteps – maximum number of steps to perform before returning false (0 or less means no max)
breakPoints – array of breakpoint program counter values, use null if none
actor – the GUI component responsible for this call, usually GO or STEP. null if none.

Returns:
true if execution completed, false otherwise

Throws:

ProcessingException – Throws exception if run-time exception occurs.

stopExecution

public void stopExecution(AbstractAction actor)

Set the volatile stop boolean variable checked by the execution
thread at the end of each MIPS instruction execution. If variable
is found to be true, the execution thread will depart
gracefully so the main thread handling the GUI can take over.
This is used by both STOP and PAUSE features.

mars.simulator

Class DelayedBranch

java.lang.Object
mars.simulator.DelayedBranch

public class DelayedBranch
extends Object

Represents a (potential) delayed branch. Note it is necessary only when
delayed branching is enabled. Here’s the protocol for using it:

(1) When a runtime decision to branch is made (by either a branch or jump
instruction’s simulate() method in InstructionSet), then if delayed branching
is enabled, the register() method is called with the branch target address but
the program counter is NOT set to the branch target address.

(2) At the end of that instruction cycle, the simulate() method in Simulator
will detect the registered branch, and set its trigger. Don’t do anything yet
because the next instruction cycle is the delay slot and needs to complete.

(3) At the end of the next (delay slot) instruction cycle, the simulate()
method in Simulator will detect the triggered branch, set the program
counter to its target value and clear the delayed branch.

The only interesting situation is when the delay slot itself contains a
successful branch! I tried this with SPIM (e.g. beq followed by b)
and it treats it as if nothing was there and continues the delay slot
into the next cycle. The eventual branch taken is the original one (as one
would hope) but in the meantime the first statement following the sequence
of successful branches will constitute the delay slot and will be executed!

Since only one pending delayed branch can be taken at a time, everything
here is done with statics. The class itself represents the potential branch.

Method Detail

register

public static void register(int targetAddress)

Register the fact that a successful branch is to occur. This is called in
the instruction’s simulated execution (its simulate() method in InstructionSet).
If a branch is registered but not triggered, this registration will be ignored
(cannot happen if class usage protocol is followed). If a branch is currently
registered and triggered, reset the state back to registered (but not triggered)
in order to carry over the delay slot for another execution cycle. This is the
only public member of the class.

Parameters:
targetAddress – The address to branch to after executing the next instruction

mars

Class Settings

java.lang.Object
java.util.Observable
mars.Settings

public class Settings
extends Observable

Contains various IDE settings. Persistent settings are maintained for the
current user and on the current machine using
Java’s Preference objects. Failing that, default setting values come from
Settings.properties file. If both of those fail, default values come from
static arrays defined in this class. The latter can can be modified prior to
instantiating Settings object.

NOTE: If the Preference objects fail due to security exceptions, changes to
settings will not carry over from one MARS session to the next.

Actual implementation of the Preference objects is platform-dependent.
For Windows, they are stored in Registry. To see, run regedit and browse to:
HKEY_CURRENT_USER\Software\JavaSoft\Prefs\mars

Macros in MARS

Writing and Using Macros

.macro, .end_macro,.eqv and .include directives are new in MARS 4.3

Introduction to macros

Patterson and Hennessy define a macro as a pattern-matching and replacement facility
that provides a simple mechanism to name a frequently used sequence of instructions [1].
This permits the programmer to specify the instruction sequence by invoking the macro. This requires
only one line of code for each use instead of repeatedly typing
in the instruction sequence each time. It follows the axiom “define once, use many times,” which
not only reduces the chance for error but also facilitates program maintenance.

Macros are like procedures (subroutines) in this sense but operate differently than procedures.
Procedures in MIPS assembly language follow particular protocols for procedure definition, call and return.
Macros operate by substituting the macro body for each use at the time of assembly. This substitution
is called macro expansion.. They do not require the protocols and execution overhead of procedures.

As a simple example, you may want to terminate your program from a number of locations. If you are running
from the MARS IDE, you will use system call 10, exit. The instruction sequence is pretty easy

li $v0,10
syscall

but still tedious. You can define a macro, let’s call it done, to represent this sequence

.macro done
li $v0,10
syscall
.end_macro

then invoke it whenever you wish with the statement

done

At assembly time, the assembler will replace each occurrence of the statement done with the two-statement
sequence

li $v0,10
syscall

This is the macro expansion. The runtime simulator is unaware of macros or macro expansion.

If running MARS from the command line, perhaps you want to return a termination value. This can be done
with syscall 17, exit2, which takes the termination value as an argument. An equivalent macro,
let’s call it terminate would be

.macro terminate (%termination_value)
li $a0, %termination_value
li $v0, 17
syscall
.end_macro

This macro defines a formal parameter to represent the termination value. You would invoke it
with the statement

terminate (1)

to terminate with value 1. Upon assembly,
the statement terminate (1) would be replaced by the three-statement sequence

li $a0, 1
li $v0, 17
syscall

The argument value, 1, is substituted wherever the formal parameter %termination_value appears
in the macro body.
This is a textual substitution. Note that in this example the argument value must be an integer, not a
register name or a label, because the parameter is used as the second operand in the Load Immediate operation.

In MARS, a macro is similar to an extended (pseudo) instruction. They are distinguished in that the expansion of
extended instructions is supported by an internally-defined specification language and mechanism which can manipulate argument values.
The macro facility can only substitute argument values as given, and it uses a separate mechanism from extended instructions.

Additional examples and details follow.

How to define macros

The first line begins with a .macro directive followed by an optional list of formal parameters.
Placing commas between parameters and parentheses around the list is optional.

Each formal parameter is an identifier that begins with a % character. For compatibility with
the SPIM preprocessor APP, it may alternatively begin with $.

The lines that follow define the body of the macro. Use the formal parameters as appropriate. The body
may contain data segments as well as text segments.

The macro definition finishes with a .end_macro directive.

See the Notes below for additional information.

How to use macros

To invoke a macro, form a statement consisting of the macro name and then one token for each argument
to be substituted for its corresponding formal parameter by the assembler.
The argument list may optionally be surrounded by parentheses.
Arguments may be separated either by spaces or commas.

Macro expansion is a pre-processing task for assemblers.

Notes

A macro definition must appear before its use. No forward references.

All macro definitions are local in each file and they cannot be global.

Nested macro definitions are not supported. No .macro directive should appear inside body of a macro definition.

A macro definition can contain a call to a previously-defined macro. Only backward references are allowed.

Labels placed in the body of a macro definition will not have same name after macro expansion.
During expansion, their name will be followed by “_M#” where # will be a unique number for each macro expansion.

Two macros with the same name but different number of parameters are considered different and both can be used.

A macro defined with the same name and same number of parameters as another macro defined before it will be ignored.

Each argument in a macro call can only be a single language element (token). For instance “4($t0)” cannot be an argument.

Macros are a part of the assembler, not the ISA. So the syntax might be different with other assemblers.
For compatibility with the SPIM simulator, SPIM-style macros are also supported in MARS. SPIM-style macros are same as MARS but formal parameters begin with “$” instead of “%”.

Examples

Printing an integer (argument may be either an immediate value or register name):
.macro print_int (%x)
li $v0, 1
add $a0, $zero, %x
syscall
.end_macro

print_int ($s0)
print_int (10)

Printing a string (macro will first assign a label to its parameter in data segment then print it):
.macro print_str (%str)
.data
myLabel: .asciiz %str
.text
li $v0, 4
la $a0, myLabel
syscall
.end_macro

print_str (“test1″) #”test1” will be labeled with name “myLabel_M0”
print_str (“test2″) #”test2” will be labeled with name “myLabel_M1”

Implementing a simple for-loop:
# generic looping mechanism
.macro for (%regIterator, %from, %to, %bodyMacroName)
add %regIterator, $zero, %from
Loop:
%bodyMacroName ()
add %regIterator, %regIterator, 1
ble %regIterator, %to, Loop
.end_macro

#print an integer
.macro body()
print_int $t0
print_str “\n”
.end_macro

#printing 1 to 10:
for ($t0, 1, 10, body)

The for macro has 4 parameters. %regIterator should be the name of a register which iterates from %from to %to and in each iteration %bodyMacroName will be expanded and run.
Arguments for
%from and %to can be either a register name or an immediate value, and %bodyMacroName should be name of a macro that has no parameters.

Macro source line numbers

For purpose of error messaging and Text Segment display, MARS attempts to display line numbers for both the definition and use of the pertinent
macro statement. If an error message shows the line number in the form “X->Y” (e.g. “20->4”), then X is the line number in the expansion
(use) where the error was detected and Y is the line number in the macro definition. In the Text Segment display
of source code, the macro definition
line number will be displayed within brackets, e.g. “<4>“, at the point of expansion. Line numbers should correspond to the
numbers you would see in the text editor.

The .eqv directive

The .eqv directive (short for “equivalence”) is also new in MARS 4.3. It is similar to #define in C or C++. It
is used to substitute an arbitrary string for an identifier. It is useful but much less powerful than macros.
It was developed independently of the macro facility.

Using .eqv, you can specify simple substitutions that provide “define once, use many times” capability at assembly
pre-processing time. For example, once you define

.eqv LIMIT 20
.eqv CTR $t2
.eqv CLEAR_CTR add CTR, $zero, 0

then you can refer to them in subsequent code:

li $v0,1
CLEAR_CTR
loop: move $a0, CTR
syscall
add CTR, CTR, 1
blt CTR, LIMIT, loop
CLEAR_CTR

During assembly pre-processing, the .eqv substitutions will be applied. The resulting code is

li $v0,1
add $t2, $zero, 0
loop: move $a0, $t2
syscall
add $t2, $t2, 1
blt $t2, 20, loop
add $t2, $zero, 0

which when run will display the values 0 through 19 on one line with no intervening spaces.

Note that the substitution string is not limited to a single token. Like .macro, .eqv is local to the file
in which it is defined, and must be defined prior to use. Macro bodies can contain references to .eqv directives.

The .include directive

The .include directive is also new in MARS 4.3. It has one operand, a quoted filename. When the
directive is carried out, the contents of the specified file are substituted for the directive. This occurs
during assembly preprocessing. It is like #include in C or C++.

.include is designed to make macro and equivalence (.eqv directive) use
more convenient. Both macro definitions and equivalence definitions are local, which means they can be used only
in the same file where defined. Without .include, you would have to repeat their definitions in every
file where you want to use them. Besides being tedious, this is poor programming practice; remember
“define once, use many times.” Now you can define macros and equivalences in a separate file, then include it
in any file where you want to use them.

The .include preprocessor will detect and flag any circular includes (file that includes itself, directly or
indirectly).

The use of .include presents some challenges for error messaging and for source code numbering in the Text
Segment display. If a file being included has any assembly errors, the filename and line number in the error
message should refer to the file being included, not the file it was substituted into. Similarly, the line number
given in the Text Segment source code display refers to the line in the file being included. Thus the displayed line numbers do not
monotonically increase – this is also the case when using the “assemble all” setting. Line numbers should correspond to the numbers
you would see in the text editor.

As a simple example, you could define the done macro (and others) in a separate file
then include it wherever you need it. Suppose “macros.asm” contains the following:

.macro done
li $v0,10
syscall
.end_macro

You could then include it in a different source file something like this:

.include “macros.asm”
.data
value: .word 13
.text
li $v0, 1
lw $a0, value
syscall
done

During assembly preprocessing, this would be expanded to

.macro done
li $v0,10
syscall
.end_macro
.data
value: .word 13
.text
li $v0, 1
lw $a0, value
syscall
done

The assembler will then perform the appropriate macro expansion.

The MARS macro facility was developed in 2012 by Mohammad Hossein Sekhavat, sekhavat17@gmail.com, while an engineering student at
Sharif University in Tehran. MARS creators Pete and Ken are incredibly grateful for his contribution! Pete developed .eqv
and .include at about the same time.

MARS 4.5 help contents

MARS – Mips Assembly and Runtime Simulator

Release 4.5

August 2014

Operating Requirements

MARS is written in Java and
requires at least Release 1.5 of the J2SE Java Runtime Environment (JRE) to work.
The graphical IDE is implemented using Swing. It has been
tested on Windows XP, Vista and 7; Mac OS X; and is also being used under Linux.

Some MARS Assembler and Simulator Limitations

Releases 3.0 and later assemble and simulate nearly all the MIPS32 instructions documented in the
textbook Computer Organization and Design, Fourth Edition by Patterson and Hennessy,
Elsevier – Morgan Kaufmann, 2009. All basic and pseudo instructions, directives,
and system services described in Appendix B are implemented.

Limitations of MARS as of Release 4.5 include:

Memory segments (text, data, stack, kernel text, kernel data) are limited to 4MB each starting at their
respective base addresses.
There is no pipelined mode (but delayed branching is supported).
If you open a file which is a link or shortcut to another file, MARS will not
open the target file. The file open dialog is implemented using Java Swing’s JFileChooser,
which does not support links.
Very few configuration changes, besides those in the Settings menu, are saved from one session to the next.
The editor settings, which include font settings and display of line numbers, are saved.
The IDE will work only with the MARS assembler. It cannot be used
with any other compiler, assembler, or simulator. The MARS assembler and simulator
can be used either through the IDE or from a command prompt.
Bug:The error message highlighter does not automatically select the code for the first assembly
error if the file containing the error is not open at the time of assembly (assemble-on-open, assemble-all).
Bug: The Screen Magnifier screen capture feature does not appear to work properly under Windows Vista.
Bug: There appears to be a memory leak in the Editor. Several different people have independently
reported the same behavior: severe slowdown in editor response during an extended interactive session.
If MARS is exited and restarted, this behavior disappears and the editor responds instantly to actions.
Not a bug, but documented here anyway: MIPS Branch instruction target addresses are represented by
the relative number of words to branch. With Release 3.4, this value reflects delayed branching,
regardless of whether the Delayed Branching setting is enabled or not.
The generated binary code for branches will now match that of examples in the Computer Organization
and Design textbook. This is a change from the past, and was made after extensive discussions
with several faculty adopters of MARS. Previously, the branch offset was 1 lower if the Delayed Branching setting
was enabled — the instruction label: beq $0,$0,label would generate 0x1000FFFF if
Delayed Branching was enabled and 0x10000000 if it was disabled. Now it will generate 0x1000FFFF in
either case. The simulator will always branch to the correct location; MARS does not allow assembly under one
setting and simulation under the other to occur.

MARS 4.5 help contents

MARS – Mips Assembly and Runtime Simulator

Release 4.5

August 2014

Configuration Settings

Releases 3.0 and later include a Settings menu. The Editor and Exception Handler items launch a dialog but the rest are each
controlled by a checkbox for selecting or deselecting it (checked means true, unchecked means false). Settings and their default
values are:
Display the Labels window in the Execute tab. Default value is false. If selected, the Labels window,
which shows the name and associated address for each label defined in the program, will be
displayed to the right of the Text Segment.
Provide program arguments to the MIPS program. Default value is false. New in Release 3.5.
If selected, a text field will appear at the top of the Text Segment Display. Any argument values in this
text field at the time of program execution will be stored in MIPS memory prior to execution. The argument
count (argc) will be placed in register $a0, and the address of an array of null-terminated strings containing
the arguments (argv) will be placed in register $a1. These values are also available on the runtime stack ($sp).

Popup Dialog for input syscalls (5,6,7,8,12). New in Release 4.0. Default value is false. If selected, runtime console
input will be entered using popup dialogs (this was the only option prior to Release 4.0). Otherwise, input is entered
directly into the Run I/O tab at the bottom of the screen.
Display memory addresses in hexadecimal. Default value is true. If deselected, addresses will be displayed in decimal.
This setting can also be toggled in a checkbox on the lower border of the Data Segment Window.
Display memory and register contents in hexadecimal. Default value is true. If deselected, vlaues will be displayed in decimal.
This setting can also be toggled in a checkbox on the lower border of the Data Segment Window.
Assemble a file automatically as soon as it is opened, and initialize the File Open dialog with the most-recently opened file.
Default value is false. This is convenient if you use an external editor for composing your programs.
Assemble applies to all files in directory. Default value is false.
If selected, the file currently open in the
editor will become the “main” program in a multi-file assemble-and-link operation involving all
assembly files (*.asm; *.s) in its directory. If successful, execution will begin with the currently open file.
Assembler warnings are considered errors. Default value is false. New in Release 3.5.
If selected, the assemble operation will fail if any warnings are produced. At this time, all assembler warnings
relate to unrecognized or ignored directives. MARS may be able to assemble code produced by compilers for other MIPS
assemblers if this setting is deselected.

Initialize Program Counter to global ‘main’ if defined. Default value is false. New in Release 3.8.
If selected, the Program Counter will be initialized to the address of the text segment statement with the global label ‘main’ if it
exists. If it does not exist or if the setting is not selected, the Program Counter will be initialized to the default text segment
starting address.

Permit programs to use extended (pseudo) instructions and formats. Default value is true. This includes all memory addressing
modes other than the MIPS native mode (16 bit constant offset added to register content).
Assemble and execute programs using delayed branching. Default value is false. MIPS processors use delayed branches
as part of the pipelined design, but it can be confusing to programmers. With delayed branching, the instruction
following a branch or jump instruction will always be executed even if the branch condition is true! Assemblers
and, failing that, programmers, often deal with this by following branches and jumps with a “nop” instruction. The MARS
assembler does not insert a nop. When delayed branching was introduced in Release 3.3, the machine code generated
for a branch instruction depended on this setting since
its target value is relative to the Program Counter (PC-relative addressing). Although technically correct, this led to
confusion in the MARS community because the generated code did not match textbook examples. Starting with Release 3.4, the relative branching
offset is always calculated as if delayed branching is enabled even when it is not. The runtime simulation adjusts accordingly.
Self-modifying code. Default value is false. New in Release 4.4.
If selected, a running MIPS program can write to a user text segment address and can branch/jump to a user data segment address.
These capabilities permit a program to dynamically generate and/or modify its binary code. Also permits interactive modification of
text segment contents through either the Data Segment or Text Segment windows.

The Editor dialog. Use it to view and modify editor font settings. New with Release 3.3.
The Highlighting dialog. Use it to modify color and font settings for the highlighting of table items in the
Text Segment window, Data Segment window, Registers window, Coprocessor0 window and Coprocessor1 window.
Highlighting occurs during timed, stepped, and backstepped simulation. Color and font for normal (non-highlighted)
display can also be set separately for even-numbered and odd-numbered display rows but not individually by windows.
New with Release 3.6.
The Exception Handler dialog. It has the setting: Include this
exception handler in all assemble operations. Default value is false. If selected, a button to browse to the desired
file is enabled. New with Release 3.2
The Memory Configuration dialog. Use it to select from among available MIPS address space configurations.
The default configuration is derived from SPIM; it was only one available from MARS 1.0 through MARS 3.6.
New with Release 3.7.

Beginning with Release 3.2, settings are retained from one interactive session to the next. Settings are stored in a system-dependent
way as specified by java.util.prefs.Preferences. Windows systems use the Registry.
These settings are independent of command options given when using MARS from a command line;
neither affects the other. We anticipate future releases will include additional settings and preferences.

Writing and Using MIPS exception handlers in MARS

Writing and Using MIPS exception handlers in MARS

Introduction

Exception handlers, also known as trap handlers or
interrupt handlers, can easily be incorporated into a MIPS program.
This guide is not intended to be comprehensive but provides the essential
information for writing and using exception handlers.

Although the same mechanism services all three, exceptions, traps
and interrupts are all distinct from each other.
Exceptions are caused by exceptional conditions that occur at runtime
such as invalid memory address references. Traps are caused by instructions
constructed especially for this purpose, listed below. Interrupts are
caused by external devices.

MARS partially but not completely implements the exception and interrupt
mechanism of SPIM.

Essential Facts

Some essential facts about writing and using exception handlers include:
MARS simulates basic elements of the MIPS32 exception mechanism.
The MIPS instruction set includes a number of instructions that
conditionally trigger a trap exception based on the relative values of two
registers or of a constant and a register:
teq, teqi (trap if equal),
tne, tnei (trap if not equal),
tge, tgeu,
tgei, tgeiu (trap if greater than or equal),
tlt, tltu,
tlti, tltiu (trap if less than)

When an exception occurs,
Coprocessor 0 register $12 (status) bit 1 is set
Coprocessor 0 register $13 (cause) bits 2-6 are set to the exception type (codes below)
Coprocessor 0 register $14 (epc) is set to the
address of the instruction that triggered the exception
If the exception was caused by an invalid memory address,
Coprocessor 0 register $8 (vaddr) is set to the invalid address.
Execution flow jumps to the MIPS
instruction at memory location 0x800000180. This address
in the kernel text segment (.ktext directive) is the
standard MIPS32 exception handler location. The only way to change
it in MARS is to change the MIPS memory configuration through
the Settings menu item Memory Configuration.

There are three ways to include an exception handler in a MIPS program
Write the exception handler in the same file as the regular
program. An example of this is presented below.

Write the exception handler in a separate file, store that file
in the same directory as the regular program, and select
the Settings menu item “Assemble all files in directory”

Write the exception handler in a separate file, store that file
in any directory, then open the “Exception Handler…” dialog
in the Settings menu, check the check box and browse to
that file.

If there is no instruction at location 0x800000180,
MARS will terminate the MIPS program with an appropriate error message.

The exception handler can return control to the program using
the eret instruction. This will place the EPC register $14 value into the
Program Counter, so be sure to increment $14 by 4 before returning
to skip over the instruction that caused the exception. The mfc0
and mtc0 instructions are used to read from and write to Coprocessor 0
registers.
Bits 8-15 of the Cause register $13 can also be used to indicate
pending interrupts. Currently this is used only by the Keyboard and
Display Simulator Tool, where bit 8 represents a keyboard interrupt
and bit 9 represents a display interrupt. For more details, see the
Help panel for that Tool.

Exception types declared in mars.simulator.Exceptions, but
not necessarily implemented, are ADDRESS_EXCEPTION_LOAD (4), ADDRESS_EXCEPTION_STORE (5),
SYSCALL_EXCEPTION (8),
BREAKPOINT_EXCEPTION (9),
RESERVED_INSTRUCTION_EXCEPTION (10),
ARITHMETIC_OVERFLOW_EXCEPTION (12),
TRAP_EXCEPTION(13),
DIVIDE_BY_ZERO_EXCEPTION (15),
FLOATING_POINT_OVERFLOW (16), and
FLOATING_POINT_UNDERFLOW (17).

When writing a non-trivial exception handler, your handler must first save
general purpose register contents, then restore them before returning.

Example of Trap Handler

The sample MIPS program below will immediately generate a trap exception because
the trap condition evaluates true, control jumps to the exception handler,
the exception handler returns control to the instruction following
the one that triggered the exception, then the program terminates normally.

.text
main:
teqi $t0,0 # immediately trap because $t0 contains 0
li $v0, 10 # After return from exception handler, specify exit service
syscall # terminate normally

# Trap handler in the standard MIPS32 kernel text segment

.ktext 0x80000180
move $k0,$v0 # Save $v0 value
move $k1,$a0 # Save $a0 value
la $a0, msg # address of string to print
li $v0, 4 # Print String service
syscall
move $v0,$k0 # Restore $v0
move $a0,$k1 # Restore $a0
mfc0 $k0,$14 # Coprocessor 0 register $14 has address of trapping instruction
addi $k0,$k0,4 # Add 4 to point to next instruction
mtc0 $k0,$14 # Store new address back into $14
eret # Error return; set PC to value in $14
.kdata
msg:
.asciiz “Trap generated”

Widely Used Exception Handler

The exception handler exceptions.s provided with
the SPIM simulator will assemble and run under MARS. The MARS
assembler will generate warnings because this program
contains directives that it does not
recognize, but as long as the setting “Assembler warnings are
considered errors” is not set this will not cause any
problems.

MARS 4.5 help contents

MARS – Mips Assembly and Runtime Simulator

Release 4.5

August 2014

Using MARS through its Integrated Development Environment (IDE)

The IDE is invoked when MARS is run with no command arguments, e.g. java -jar mars.jar.
It may also be launched from a graphical interface by double-clicking the mars.jar icon
that represents this executable JAR file.
The IDE provides basic editing, assembling and execution capabilities. Hopefully it
is intuitive to use. Here are comments on some features.
Menus and Toolbar: Most menu items have equivalent toolbar icons.
If the function of a toolbar icon is not obvious, just hover the mouse over it and
a tool tip will soon appear. Nearly all menu items also have keyboard shortcuts.
Any menu item not appropriate in a given situation is disabled.
Editor: MARS includes two integrated text editors. The default editor, new
in Release 4.0, features syntax-aware color highlighting of most MIPS language elements
and popup instruction guides. The original, generic, text editor without these features
is still available and can be selected in the Editor Settings dialog. It supports a single
font which can be modified in the Editor Settings dialog.
The bottom border of either editor includes the cursor line
and column position and there is a checkbox to display line numbers.
They are displayed outside the editing area. If you use an external editor, MARS provides
a convenience setting that will automatically assemble a file as soon as it is opened. See
the Settings menu.

Message Areas: There are two tabbed message areas at the
bottom of the screen. The Run I/O tab is used at runtime for
displaying console output and entering console input as program execution progresses.
You have the option of entering console input into a pop-up dialog then echoes to the message area.
The MARS Messages tab is used for other messages such as assembly or
runtime errors and informational messages. You can click on assembly error messages to
select the corresponding line of code in the editor.

MIPS Registers: MIPS registers are displayed at all times, even
when you are editing and not running a program. While writing your program,
this serves as a useful reference for register names and their conventional
uses (hover mouse over the register name to see tool tips). There are three
register tabs: the Register File (integer registers $0 through $31 plus LO,
HI and the Program Counter), selected Coprocesor 0 registers (exceptions and
interrupts), and Coprocessor 1 floating point registers.

Assembly: Select Assemble from the Run menu or the
corresponding toolbar icon to assemble the file currently in the Edit tab.
Prior to Release 3.1, only one file could be assembled and run at a time.
Releases 3.1 and later provide a primitive Project capability. To use it, go to the
Settings menu and check Assemble operation applies to all
files in current directory. Subsequently, the assembler will assemble
the current file as the “main” program and also assemble all other assembly
files (*.asm; *.s)
in the same directory. The results are linked and if all these
operations were successful the program can be executed. Labels that are
declared global with the “.globl” directive may be referenced in any of the
other files in the project. There is also a setting that permits
automatic loading and assembly of a selected exception handler file. MARS uses
the MIPS32 starting address for exception handlers: 0x80000180.

Execution: Once a MIPS program successfully assembles, the
registers are initialized and three windows
in the Execute tab are filled: Text Segment, Data Segment,
and Program Labels. The major execution-time features are described below.

Labels Window: Display of the Labels window (symbol table) is
controlled through the Settings menu. When displayed, you can click on any label
or its associated address to center and highlight the contents of that address
in the Text Segment window or Data Segment window as appropriate.

The assembler and simulator are invoked from the IDE
when you select the Assemble, Go,
or Step operations from the Run menu or their corresponding
toolbar icons or keyboard shortcuts. MARS messages are displayed on the
MARS Messages tab of the message area at the bottom of the screen.
Runtime console input and output is handled in the Run I/O tab.

MARS – Mips Assembly and Runtime Simulator

Release 4.5

August 2014

Introduction

MARS, the Mips Assembly and Runtime Simulator,
will assemble and simulate the execution of MIPS assembly language programs.
It can be used either from a command line or through its
integrated development environment (IDE). MARS is written in Java and
requires at least Release 1.5 of the J2SE Java Runtime Environment (JRE) to work.
It is distributed as an executable JAR file.
The MARS home page
is
http://www.cs.missouristate.edu/MARS/. This document is available for printing there.

As of Release 4.0, MARS assembles and simulates 155 basic instructions of the MIPS-32
instruction set, approximately 370 pseudo-instructions or instruction variations, the 17 syscall functions
mainly for console and file I/O defined by SPIM, and an additional 22 syscalls for other uses such as MIDI
output, random number generation and more. These are listed in separate help tabs. It supports seven
different memory addressing modes for load and store instructions: label, immed,
label+immed, ($reg), label($reg), immed($reg), and label+immed($reg), where immed
is an integer up to 32 bits. A setting is available to disallow use of pseudo-instructions
and extended instruction formats and memory addressing modes.

Our guiding reference in implementing the instruction set has been
Computer Organization and Design, Fourth Edition by Patterson and Hennessy,
Elsevier – Morgan Kaufmann, 2009. It summarizes the MIPS-32 instruction set
and pseudo-instructions in Figures 3.24 and 3.25 on pages 279-281, with details
provided in the text and in Appendix B. MARS Releases 3.2 and above implement all the instructions
in Appendix B and those figures except the delay branches from the left column of Figure 3.25.
It also implements all the system services (syscalls) and assembler directives
documented in Appendix B.

The MARS IDE provides program editing and assembling but its real
strength is its support for interactive debugging. The programmer can easily set and
remove execution breakpoints or step through execution forward or backward (undo) while
viewing and directly editing register and memory contents.

MARS 4.5 help contents

MARS – Mips Assembly and Runtime Simulator

Release 4.5

August 2014

Interactive Debugging Features

MARS provides many features for interactive debugging through its Execute pane.
Features include:

In Step mode, the next instruction to be simulated is highlighted and
memory content displays are updated at each step.
Select the Go option if you want to simulate continually.
It can also be used to continue simulation
from a paused (step, breakpoint, pause) state.
Breakpoints are easily set and reset using the check boxes next to each instruction displayed
in the Text Segment window. New in Release 3.8: You can temporarily suspend breakpoints
using Toggle Breakpoints in the Run menu or by clicking the “Bkpt” column header in the Text Segment
window. Repeat, to re-activate.
When running in the Go mode, you can select the simulation
speed using the Run Speed slider. Available speeds range
from .05 instructions per second (20 seconds between steps) up to 30
instructions per second, then above this offers an “unlimited” speed.
When using “unlimited” speed, code highlighting and memory display updating
are turned off while simulating (but it executes really fast!).
When a breakpoint is reached, highlighting and updating occur.
Run speed can be adjusted while the program is running.
When running in the Go mode, you can pause or stop
simulation at any time using the Pause or Stop features.
The former will pause execution and update the display, as if you
were stepping or at a breakpoint. The latter will terminate execution
and display final memory and register values. If running at “unlimited”
speed, the system may not respond immediately but it will respond.
You have the ability to interactively step “backward” through program execution
one instruction at a time to “undo” execution steps. It will buffer up to 2000 of the most
recent execution steps (this limit is stored in a properties file and can be changed).
It will undo changes made to MIPS memory, registers or condition flags,
but not console or file I/O. This should be a great debugging aid.
It is available anytime execution is paused and at termination (even if terminated due to
exception).

When program execution is paused or terminated, select Reset
to reset all memory cells and registers to their initial post-assembly values.
In fact, Reset is implemented by re-assembling the program.
Memory addresses and values, and register values, can be viewed in either decimal
or hexadecimal format. All data are stored in little-endian byte order (each
word consists of byte 3 followed by byte 2 then 1 then 0). Note that each word
can hold 4 characters of a string and those 4 characters will appear in the
reverse order from that of the string literal.
Data segment contents are displayed 512 bytes
at a time (with scrolling) starting with the data segment base address (0x10010000).
Navigation buttons are provided to change the display to the next
section of memory, the previous, or back to the initial (home) range. A combo box is
also provided to view memory contents in the vicinity of the stack pointer
(contents of MIPS $sp register), global pointer (contents of MIPS $gp register),
the heap base address (0x10040000), .extern globals (0x10000000),
the kernel data segment (0x90000000), or memory-mapped IO (MMIO, 0xFFFF0000).
Starting with Mars 4.4, raw text segment contents can also be displayed.
Contents of any data segment memory word and almost any MIPS register can be modified by
editing its displayed table cell. Double-click on a cell to edit it and press the Enter key
when finished typing the new value. If you
enter an invalid 32-bit integer, the word INVALID appears in the cell
and memory/register contents are not affected. Values can be entered
in either decimal or hexadecimal (leading “0x”). Negative hexadecimal
values can be entered in either two’s complement or signed format. Note
that three of the integer registers (zero, program counter, return address)
cannot be edited.
New in 4.4 If the setting for Self-Modifying Code is enabled
(disabled by default, look in the Settings menu), text segment binary
code can be modified using the same technique described above. It can also
be modified by double-clicking on a cell in the Text Segment display’s Code
column.
Contents of cells representing floating point registers can be edited
as described above and will accept valid hexadecimal or decimal floating point
values. Since each double-precision register overlays two single-precision
registers, any changes to a double-precision register will affect one or both
of the displayed contents of its corresponding single-precision registers.
Changes to a single-precision register will affect the display of its
corresponding double-precision register. Values entered in hexadecimal
need to conform to IEEE-754 format. Values entered in decimal are entered
using decimal points and E-notation (e.g. 12.5e3 is 12.5 times 10 cubed).
Cell contents can be edited during program execution and once accepted
will apply starting with the next instruction to be executed.
Clicking on a Labels window entry will cause the location associated with
that label to be centered and highlighted in the Text Segment or Data Segment
window as appropriate. Note the Labels window is not displayed by default but
can be by selecting it from the Settings menu.

MARS – Mips Assembly and Runtime Simulator

Release 4.5

August 2014

Using MARS from a command line.

MARS can be run from a command interpreter to assemble and execute a MIPS program in
a batch fashion.
The format for running MARS from a command line is:

java -jar mars.jar [options] program.asm [more files…] [ pa arg1 [more args…]]

Items in [ ] are optional. Valid options (not case sensitive, separated by spaces) are:

Option Description Since
a assemble only, do not simulate 1.0
aen terminate MARS with integer exit code n if assembly error occurs 4.1
ascii display memory or register contents interpreted as ASCII codes. (alternatives are dec and hex) 4.1
b brief – do not display register/memory address along with contents 2.2
d display MARS debugging statements (of interest mainly to MARS developer) 1.0
db MIPS delayed branching is enabled. 3.3
dec display memory or register contents in decimal. (alternatives are ascii and hex) 2.2
dump dump memory contents to file.
Option has 3 arguments, e.g. dump . Current supported segments are .text
and .data. Also supports an address range (see m-n below). Current supported dump formats are Binary, HexText, BinaryText, AsciiText. See examples below. 3.4
hex display memory or register contents in hexadecimal – this is the default. (alternatives are ascii and dec) 2.2
h display this help. Use this option by itself and with no filename. 1.0
ic display instruction count; the number of MIPS basic instructions ‘executed’ 4.3
mc set memory configuration.
Option has 1 argument, e.g. mc . Argument is case-sensitive and its
possible values are Default for the default 32-bit address space, CompactDataAtZero for
a 32KB address space with data segment at address 0, or CompactTextAtZero
for a 32KB address space with text segment at address 0. 3.7
me display MARS messages to standard err instead of standard out. Allows you to separate MARS messages from MIPS program output using redirection. 4.3
nc copyright notice will not be displayed. Useful if redirecting or piping program output. 3.5
np pseudo-instructions or extended instruction formats are not permitted. 3.0
p project option – will assemble the specified file and all other assembly files (*.asm; *.s) in its directory. 3.1
sen terminate MARS with exit code n if simulate (run) error occurs 4.1
sm start execution at statement having global label ‘main’ if defined 3.8
smc Self Modifying Code – Program can write and execute in either text or data segment 4.4
we assembler warnings will be considered errors. 3.5
n where n is an integer maximum count of execution steps to simulate.
If 0, negative or not specified, there is no maximum. 1.0
$reg where reg is number or name (e.g. 5, t3, f10) of register whose
content to display at end of run. Even-numbered float register displays both float and double. Option may be repeated.
NOTE: Depending on your command shell, you may need to escape the $, e.g. \$t3 2.2
reg_name where reg_name is the name (e.g. t3, f10) of register whose
content to display at end of run. Even-numbered float register displays both float and double. Option may be repeated. $ not required. 2.2
m-n memory address range from m to n whose contents to
display at end of run. m and n may be decimal or hexadecimal (starts with 0x),
m <= n, both must be on word boundary. Option may be repeated. 2.2 pa program arguments - all remaining space-separated items are argument values provided to the MIPS program via $a0 (argc - argument count) and $a1 (argv - address of array containing pointers to null-terminated argument strings). The count is also at the top of the runtime stack ($sp), followed by the array.This option and its arguments must be the last items in the command! 3.5 Example: java -jar mars.jar h Displays command options and explanations. Example: java -jar mars.jar $s0 $s1 0x10010000-0x10010010 fibonacci.asm Assemble and run fibonacci.asm. At the end of the run, display the contents of registers $s0 and $s1, and the contents of memory locations 0x10010000 through 0x10010010. The contents are displayed in hexadecimal format. Example: java -jar mars.jar a fibonacci.asm Assemble fibonacci.asm. Does not attempt to run the program, and the assembled code is not saved. Example: java -jar mars.jar 100000 infinite.asm Assemble and run infinite.asm for a maximum of 100,000 execution steps. Example: java -jar mars.jar p major.asm Assemble major.asm and all other files in the same directory, link the assembled code, and run starting with the first instruction in major.asm. Example: java -jar mars.jar major.asm minor.asm sub.asm Assemble and link major.asm, minor.asm and sub.asm. If successful, execution will begin with the first instruction in major.asm. Example: java -jar mars.jar a dump .text HexText hexcode.txt fibonacci.asm Assemble fibonacci.asm without simulating (note use of 'a' option). At end of assembly, dump the text segment (machine code) to file hexcode.txt in hexadecimal text format with one instruction per line. Example: java -jar mars.jar dump 0x10010000-0x10010020 HexText hexcode.txt fibonacci.asm Assemble and simulate fibonacci.asm. At end of simulation, dump the contents of addresses 0x1001000 to 0x10010020 to file hexdata.txt in hexadecimal text format with one word per line. Example: java -jar mars.jar t0 process.asm pa counter 10 Assemble and run process.asm with two program argument values, "counter" and "10". It may retrieve the argument count (2) from $a0, and the address of an array containing pointers to the strings "count" and "10", from $a1. At the end of the run, display the contents of register $t0. The ability to run MARS from the command line is useful if you want to develop scripts (macros) to exercise a given MIPS program under multiple scenarios or if you want to run a number of different MIPS programs such as for grading purposes.

MARS 4.5 help contents MARS - Mips Assembly and Runtime Simulator Release 4.5 August 2014 Cool Capability: Plug-in Tools Beginning with Release 2.0, MARS is capable of running externally-developed software that interacts with an executing MIPS program and MIPS system resources. The requirements for such a program are: It implements the mars.tools.MarsTool interface. It is part of the mars.tools package. It compiles cleanly into a ".class" file, stored in the mars/tools directory. MARS will detect all qualifying tools upon startup and include them in its Tools menu. When a tool's menu item is selected, an instance of it will be created using its no-argument constructor and its action() method will be invoked. If no qualifying tools are found at MARS startup, the Tools menu will not appear. To use such a tool, load and assemble a MIPS program of interest then select the desired tool from the Tools menu. The tool's window will open and depending on how it is written it will either need to be "connected" to the MIPS program by clicking a button or will already be connected. Run the MIPS program as you normally would, to initiate tool interaction with the executing program. Beginning with Release 3.2, the abstract class mars.tools.AbstractMarsToolAndApplication is included in the MARS distribution to provide a substantial framework for implementing your own MARS Tool. A subclass that extends it by implementing at least its two abstract methods can be run not only from the Tools menu but also as a free-standing application that uses the MARS assembler and simulator in the background. Several Tools developed by subclassing AbstractMarsToolAndApplication are included with MARS: an Introduction to Tools, a Data Cache Simulator, a Memory Reference Visualizer, and a Floating Point tool. The last one is quite useful even when not connected to a MIPS program because it displays binary, hexadecimal and decimal representations for a 32 bit floating point value; when any of them is modified the other two are updated as well. Release 3.5 includes new tools, most notably a keyboard and display simulator that allows you to perform memory-mapped I/O (MMIO) using polled and interrupt-driven techniques as described in various references. Click its Help button for more details. If you wish to develop your own MARS Tool, you will first need to extract the MARS distribution from its JAR file if you have not already done so. All MARS tools must be stored in the mars/tools directory. Follow the Tutorial Materials link on the MARS homepage to find a tutorial that covers development of MARS Tools. Cool Capability: Extending the syscall set or reassigning syscall numbers Beginning with Release 3.1, system calls (syscall instruction) are implemented using a technique similar to that for tools. This permits anyone to add a new syscall by defining a new class that meets these requirements: It implements the mars.mips.instructions.syscalls.Syscall interface, or extends the mars.mips.instructions.syscalls.AbstractSyscall class (which provides default implementations of everything except the simulate() method). It is part of the mars.mips.instructions.syscalls package. It compiles cleanly into a ".class" file, stored in the mars/mips/instructions/syscalls directory. MARS will detect all qualifying syscall classes upon startup and the runtime simulator will invoke them when the syscall instruction is simulated and register $v0 contains the corresponding integer service number. Syscalls and syscall number assignments in MARs match those of SPIM for syscalls 1 through 17. However if you wish to change syscall number assignments, you may do so by editing the Syscall.properties file included in the release (this requires extraction from the JAR file). Follow the Tutorial Materials link on the MARS homepage to find a tutorial that covers development of system calls. Cool Capability: Extending the instruction set You can add customized pseudo-instructions to the MIPS instruction set by editing the PseudoOps.txt file included in the MARS distribution. Instruction specification formats are explained in the file itself. The specification of a pseudo-instruction is one line long. It consists of an example of the instruction, constructed using available instruction specification symbols, followed by a tab-separated list of the basic MIPS instructions it will expand to. Each is an instruction template constructed using instruction specification symbols combined with special template specification symbols. The latter permit substitution at program assembly time of operands from the user's program into the expanded pseudo-instruction. PseudoOps.txt is read and processed at MARS startup, and error messages will be produced if a specification is not correctly formatted. Note that if you wish to edit it you first have to extract it from the JAR file. Follow the Tutorial Materials link on the MARS homepage to find a tutorial that covers modification of the pseudo-instruction set. This document is available for printing on the MARS home page http://www.cs.missouristate.edu/MARS/. MARS Release History and Notes MARS - Mips Assembly and Runtime Simulator Release 4.5 August 2014 MARS Release History Mars 4.5 was released in August 2014. Enhancements and bug fixes include: The Keyboard and Display MMIO Simulator tool has been enhanced at the suggestion of Eric Wang at Washington State University. Until now, all characters written to the display via the Data Transmitter location (low order byte of memory word 0xFFFF000C) were simply streamed to the tools' display window. Mr. Wang requested the ability to treat the display window as a virtual text-based terminal by being able to programmatically clear the window or set the (x,y) position of a text cursor. Controlled placement of the text cursor (which is not displayed) allows you to, among other things, develop 2D text-mode games. To clear the window, place ASCII/Unicode 12 decimal in the Data Transmitter byte. This is the non-printing Form Feed character. To set the text cursor to a specified (x,y) position, where x is the column and y is the row, place ASCII/Unicode 7 in the Data Transmitter byte, and place the (x,y) position in the unused upper 24 bits of the Data Transmitter word. Place the X-position in bits 20-31 and the Y-position in bits 8-19. Position (0,0) is the upper-left corner of the display. You can resize the display window to desired dimensions prior to running your MIPS program. Dimensions are dynamically displayed in the upper border. Note that the tool now contains a splitter between the display window and the keyboard window. Once the program is running, changes to the display size does not affect cursor positioning. The Help window for this tool is no longer modal, so you can view it while working in other windows. The Help window contains a lot of information so you will find it useful to be able to refer to it while working on your program. Installed the MIPS X-ray Tool developed by Marcio Roberto and colleagues at the Federal Center of Technological Education of Minas Gerais in Brazil. This tool animates a display of the MIPS datapath. The animation occurs while stepping through program execution. Search the Internet for "MIPS X-ray" to find relevant publications and other information. Context-sensitive help in the editor should now be easier to read. It was implemented as a menu of disabled items, which caused their text to be dimmed. The items are now enabled for greater visibility but clicking them will only make the list disappear. Bug Fix: Fixed an editor problem that affects certain European keyboards. The syntax-highlighting editor ignored the Alt key, which some European keyboards require to produce the # or $ characters in particular. I had no means of testing this, but Torsten Maehne in France send me a solution and Umberto Villano in Italy affirmed that it worked for him as well. Bug Fix: Source code references to Coprocessor 1 floating point registers (e.g. $f12) within macro definitions were erroneously flagged as syntax errors. MARS permits SPIM-style macro parameters (which start with $ instead of %) and did not correctly distinguish them from floating point register names. This has been fixed. Thanks to Rudolf Biczok in Germany for alerting me to the bug. Bug Fix: Corrected a bug that caused the Data Segment window to sometimes display incorrect values at the upper boundary of simulated memory segments. Thanks to Yi-Yu (James) Liu from Taiwan for alerting me to the bug, which was introduced in Mars 4.4. Mars 4.4 was released in August 2013. Enhancements and bug fixes include: A feature to support self-modifying code has been developed by Carl Burch (Hendrix College) and Pete Sanderson. It is disabled by default and can be enabled through a Settings menu option. A program can write to the text segment and can also branch/jump to any user address in the data segments within the limits of the simulated address space. Text segment contents can also be edited interactively using the Data Segment window, and text segment contents within the address range of existing code can be edited interactively using the Text Segment window. In command mode, the smc option permits a program to write and execute in both text and data segments. Bug fix: An assembly error occurred when a line within a macro contained both a macro parameter and an identifier defined to have an .eqv substitution. Bug fix: If a macro name was used as a macro parameter, an assembly error occurred in some situations when a macro being used as an argument was defined following the macro that defined the parameter. The "for" macro described in the Macro help tab is an example. Mars 4.3 was released in January 2013. Enhancements and bug fixes include: A macro facility has been developed by Mr. Mohammad Sekhavat. It is documented in the MIPS help tab Macros. A text substitution facility similar to #define has been developed using the new .eqv directive. It is also documented in the MIPS help tab Macros. A text insertion facility similar to #include has been developed using the new .include directive. It is also documented in the MIPS help tab Macros. It permits a macro to be defined in one file and included wherever needed. Two new command mode options are now available: ic (Instruction Count) to display a count of statements executed upon program termination, and me (Messages to Error) to send MARS messages to System.err instead of System.out. Allows you to separate MARS messages from MIPS output using redirection, if desired. Redirect a stream in DOS with "1>” or “2>” for out and err,
respectively. To redirect both, use “> filename 2>&1”

Changed the default font family settings from Courier New to Monospaced.
This was in response to reports of Macs displaying left parentheses and vertical
bars incorrectly.

Changed the way operands for .byte and .half directives are range-checked.
It will now work like SPIM, which accepts any operand value but truncates high-end bits as
needed to fit the 1 (byte) or 2 (half) byte field. We’ll still issue a warning
but not an error.

For file reads, syscall 14, file descriptor 0 is always open for standard input. For file
writes, syscall 15, file descriptors 1 and 2 are always open for standard output and
standard error, respectively. This permits you to write I/O code that will
work either with files or standard I/O. When using the IDE, standard input and output
are performed in the Run I/O tab. File descriptors for regular files are
allocated starting with file descriptor 3.

Mars 4.2 was released in August 2011. Enhancements and bug fixes include:

Performing a Save operation on a new file will now use the file’s tab
label as the the default filename in the Save As dialog (e.g. mips1.asm).
Previously, it did not provide a default name.

When the “assemble all files in directory” setting is enabled (useful
for multi-file projects), you can now switch focus from one editor tab to another
without invalidating the current assemble operation. You can similarly open
additional project files. Previously, the open or tab selection would
invalidate the assemble operation and any paused execution state or
breakpoints would be lost.

The Read String syscall (syscall 8) has been fortified to prevent Java exceptions from occurring
when invalid values are placed in $a1.

Will now perform runtime test for unaligned doubleword address in
‘ldc1’ and ‘sdc1’ instructions and trap if not aligned.

Basic statements in the Text Segment display now renders immediates using
eight hex digits when displaying in hex. Previously it rendered only
four digits to conserve space. This led to confusing
results. For instance, -1 and 0xFFFF would both be displayed as 0xFFFF
but -1 expands to 0xFFFFFFFF and 0xFFFF expands to 0x0000FFFF.

Mars 4.1 was released in January 2011. Enhancements and bug fixes include:

The ability to view Data Segment contents interpreted as ASCII
characters has been added. You’ll find it on the bottom border of
the Data Segment Window as the checkbox “ASCII”. This overrides the
hexadecimal/decimal setting but only for the Data Segment display.
It does not persist across sessions. Cells cannot be edited in
ASCII format.

The Dump Memory feature in the File menu now provides an ASCII dump
format. Memory contents are interpreted as ASCII codes.

A command-mode option “ascii” has been added to display memory or
register contents interpreted as ASCII codes. It joins the existing
“dec” and “hex” options for displaying in decimal or hexadecimal,
respectively. Only one of the three may be specified.

The actual characters to display for all the ASCII display options
(data segment window, dump memory, command-mode option) are
specified in the config.properties file. This includes a “placeholder”
character to be displayed for all codes specified as non-printing.
ASCII codes 1-7, 14-31, and 127-255 are specified as
non-printing, but this can be changed in the properties file.

A new Help tab called Exceptions has been added. It explains the basics
of MIPS exceptions and interrupts as implemented in MARS. It also includes
tips for writing and using exception handlers.

A new Tool called Bitmap Display has been added. You can use it
to simulate a simple bitmap display. Each word of the specified address
space represents a 24 bit RGB color (red in bits 16-23, green in bits
8-15, blue in bits 0-7) and a word’s value will be displayed on the Tool’s
display area when the word is written to by the MIPS program. The base
address corresponds to the upper left corner of the display, and words are
displayed in row-major order. Version 1.0 is pretty basic, constructed
from the Memory Reference Visualization Tool code.

Additional operand formats
were added for the multiplication pseudo-instructions ‘mul’ and ‘mulu’.

The editor’s context-sensitive pop-up help will now appear below
the current line whenever possible. Originally it appeared either above,
centered to the side,
or below, depending on the current line’s vertical position in the editing
window. Displaying the pop-up above the current line tended to visually block
important information, since frequently a line of code uses the same operand
(especially registers) as the one immediately above it.

The editor will now auto-indent each new line when the Enter
key is pressed. Indentation of the new line will match that of the
line that precedes it. This feature can be disabled in the Editor settings dialog.

Two new command-mode options have been added. The “aeN” option, where
N is an integer, will terminate MARS with exit value N when an assemble error
occurs. The “seN” option will similarly terminate MARS with exit value
N when a simulation (MIPS runtime) error occurs. These options can be useful
when writing scripts for grading. Thanks to my Software
Engineering students Robert Anderson, Jonathan Barnes, Sean Pomeroy, and Melissa Tress
for designing and implementing these options.

An editor bug that affected Macintosh users has been fixed.
Command shortcuts, e.g. Command-s for save, did not
function and also inserted the character into the text.

A bug in Syscall 54 (InputDialogString) has been fixed. This syscall is
the GUI equivalent of Syscall 8 (ReadString), which follows the semantics
of UNIX ‘fgets’. Syscall 54 has been modified to also follow the ‘fgets’
semantics.

A bug in the Cache Simulator Tool has been fixed. The animator that
paints visualized blocks green or red (to show cache hit or miss) sometimes
paints the wrong block when set-associated caching is used. The underlying
caching algorithm is correct so the numeric results such as hit ratios
have always been correct. The animator has been corrected.
Thanks to Andreas Schafer and his student Carsten Demel for bringing this
to my attention.

Mars 4.0.1 was released in October 2010. It is a bug fix release to address three bugs.

The Edit and Execute tabs of the IDE, which were relocated in 4.0 from the top to the left edge and oriented vertically, have been
moved back to the top edge because Macintosh running Java 1.6 does not correctly render vertically-oriented tabs.

An exception may be thrown in multi-file assembles when the last file of the assembly is not the longest. This occurs
only when using the IDE, and has been corrected.

If an assemble operation fails due to a non-existing exception handler file (specified through the IDE Settings menu), unchecking
the exception handler setting does not prevent the same error from occuring on the next assemble. This has been corrected.

Mars 4.0 was released in August 2010. Enhancements and bug fixes include:

New Text Editor: Mars features an entirely new integrated text editor. It creates a new tab for each file
as it is opened. The editor now features language-aware
color highlighting of many MIPS assembly language elements with customizable
colors and styles. It also features automatic context-sensitive popup instruction
guides. There are two levels: one with help and autocompletion of instruction names
and a second with help information for operands. These and other new editor
features can be customized or disabled through
the expanded Editor Settings dialog. You can even revert to the previous
notepad-style editor if you wish (multi-file capability is retained).
The language-aware editor is based on
the open source jEdit Syntax Package (syntax.jedit.org). It is separate from
the assembler, so any syntax highlighting quirks will not affect assembly.

Improved Instruction Help: All the instruction examples in the help tabs (and new popup instruction guides)
now use realistic register names, e.g. $t1, $t2, instead of $1, $2. The instruction format
key displayed above the MIPS help tabs has been expanded to include explanations of the
various addressing modes for load and store instructions and pseudo-instructions.
Descriptions have been added to every example instruction and pseudo-instruction.

Improved Assembly Error Capability: If the assemble operation results in errors, the first error message
in the Mars Messages text area will be highighted and the corresponding erroneous instruction will be selected in the
text editor. In addition, you can click on any error message in the Mars Messages text area to select the corresponding
erroneous instruction in the text editor. The first feature does not select in every situation (such as when
assemble-on-open is set) but in the situations where it doesn’t work no harm is done plus
the second feature, clicking on error messages, can still be used.

Console input syscalls (5, 6, 7, 8, 12) executed in the IDE now receive input keystrokes directly in the Run I/O text
area instead of through a popup input dialog. Thanks to Ricardo Pascual for providing this feature!
If you prefer the popup dialogs, there is a setting to restore them.

The floor, ceil, trunc and round operations now all produce the MIPS default result 2^31-1 if the value is
infinity, NaN or out of 32-bit range. For consistency, the sqrt operations now produce the result NaN if the operand is negative
(instead of raising an exception). These cases are all consistent with FCSR (FPU Control and Status Register)
Invalid Operation flag being off. The ideal solution would be to simulate the FCSR register itself so all
MIPS specs for floating point instructions can be implemented, but that hasn’t happened yet.

The Basic column in the Text Segment Window now displays data and addresses in either decimal or
hexadecimal, depending on the current settings. Note that the “address” in branch instructions
is actually an offset relative to the PC, so is treated as data not address. Since data operands in
basic instructions are no more than 16 bits long, their hexadecimal display includes only 4 digits.

The Source column in the Text Segment Window now preserves tab spacing for a cleaner appearance (tab characters were previously not rendered).

Instruction mnemonics can now be used as labels, e.g. “b:”.

New syscall 36 will display an integer as an unsigned decimal.

A new tool, Digital Lab Sim, contributed by Didier Teifreto (dteifreto@lifc.univ-fcomte.fr). This tool
features two seven-segment displays, a hexadecimal keypad, and a counter. It uses MMIO to explore
interrupt-driven I/O in an engaging setting. More information is available from its Help feature. Many thanks!

MARS 4.0 requires Java 1.5 (5.0) instead of 1.4. If this is an issue for you, let me know.

Mars 3.8 was released in January 2010. Enhancements and bug fixes include:

A new feature to temporarily suspend breakpoints you have previously set. Use it
when you feel confident enough to run your program without the breakpoints but not
confident enough to clear them! Use the Toggle Breakpoints item in the Run menu, or
simply click on the “Bkpt” column header in the Text Segment window. Repeat, to re-activate.

Two new Tools contributed by Ingo Kofler of Klagenfurt University in Austria.
One generates instruction statistics and the other simulates branch prediction using
a Branch History Table.

Two new print syscalls. Syscall 34 prints an integer in hexadecimal format.
Syscall 35 prints an integer in binary format. Suggested by Bernardo Cunha of Portugal.

A new Setting to control whether or not the MIPS program counter will be
initialized to the statement with global label ‘main’ if such a statement exists. If
the setting is unchecked or if checked and there is no ‘main’, the program counter
will be initialized to the default starting address. Release 3.7 was programmed
to automatically initialize it to the statement labeled ‘main’. This led to
problems with programs that use the standard SPIM exception handler exceptions.s
because it includes a short statement sequence at the default starting address
to do some initialization then branch to ‘main’. Under 3.7 the initialization
sequence was being bypassed. By default this setting is unchecked. This
option can be specified in command mode using the ‘sm’ (Start at Main) option.

Mars Tools that exist outside of Mars can now be included in the Tools
menu by placing them in a JAR and including it in a command that launches
the Mars IDE. For example: java -cp plugin.jar;Mars.jar Mars
Thanks to Ingo Kofler for thinking of this technique and providing the
patch to implement it.

Corrections and general improvements to the MIDI syscalls. Thanks to Max Hailperin
of Gustavus Adolphus College for supplying them.

Correction to an assembler bug that flagged misidentified invalid MIPS instructions
as directives.

Mars 3.7 was released in August 2009. Enhancements and bug fixes include:

A new feature for changing the address space configuration of the
simulated MIPS machine. The 32-bit address space configuration used by
all previous releases remains the default. We have defined two
alternative configurations for a compact 32KB address space. One starts the
text segment at address 0 and the other starts the data segment at address 0.
A 32KB address space permits commonly-used load/store pseudo-instructions
using labels, such as lw $t0,increment, to expand to a single basic
instruction since the label’s full address will fit into the 16-bit address
offset field without sign-extending to a negative value. This was done in response to
several requests over the years for smaller addresses and simplified expansions
to make assembly programs easier to comprehend. This release does not
include the ability to define your own customized configuration, although we
anticipate adding it in the future. It is available both through the command
mode (option mc) and the IDE.
See Memory Configuration… at the bottom of the Settings menu.
Related to the previous item: load and store pseudo-instructions of the form
lw $t0,label and lw $t0,label($t1) will expand to a single
instruction (addi for these examples) if the current memory configuration assures the
label’s full address will fit into the low-order 15 bits. Instructions
for which this was implemented are: la, lw, lh, lb, lhu, lbu, lwl, lwr, ll,
lwc1, ldc1, l.s, l.d, sw, sh, sb, swl, swr, sc, swc1, sdc1,
s.s, and s.d.
If a file contains a global statement label “main” (without quotes, case-sensitive), then execution will
begin at that statement regardless of its address. Previously, program execution
always started at the base address of the text segment. This will be handy for
multi-file projects because you no longer need to have the “main file” opened in
the editor in order to run the project. Note that main has to be declared global
using the .globl directive.
We have added a Find/Replace feature to the editor. This has been another
frequent request. Access it through the Edit menu or Ctrl-F. Look for major
enhancements to the editor in 2010!
The syscalls for Open File (13), Read from File (14), and Write to File (15)
all now place their return value into register $v0 instead of $a0. The table
in Computer Organization and Design’s Appendix B on SPIM specifies
$a0 but SPIM itself consistently uses $v0 for the return values.
Pseudo-instructions for div, divu, mulo, mulou, rem, remu, seq, sne, sge,
sgeu, sgt, sgtu, sle, sleu now accept a 16- or 32-bit immediate as their third operand.
Previously the third operand had to be a register.
Existing Tools were tested using reconfigured memory address space (see first item). Made some
adaptations to the Keyboard and Display Simulator Tool that allow it to be used for
Memory Mapped I/O (MMIO) even under the compact memory model, where the MMIO base address
is 0x00007f00 instead of 0xffff0000. Highlighting is not perfect in this scenario.
Bug Fix: The syscall for Open File (13) reversed the meanings of the
terms mode and flag. Flags are used to indicate the intended
use of the file (read/write). Mode is used to set file permissions in specific situations.
MARS implements selected flags as supported by Java file streams,
and ignores the mode if specified. For more details, see the Syscalls
tab under Help. The file example in that tab has been corrected.
Bug Fix: The assembler incorrectly generated an
error on Jump instructions located in the kernel text segment.
Bug Fix: The project (p) option in the command interface worked incorrectly
when MARS was invoked within the directory containing the files to be assembled.
Acknowledgement: The development of Release 3.7 was supported by a SIGCSE
Special Projects Grant.

Mars 3.6 was released in January 2009. Enhancements and bug fixes include:

We’ve finally implemented the most requested new feature: memory and register cells will
be highlighted when written to during timed or stepped simulation! The
highlighted memory/register cell thus represents the result of the instruction just completed.
During timed or stepped execution, this is NOT the highlighted instruction. During back-stepping,
this IS the highlighted instruction. The highlighted instruction is the next one
to be executed in the normal (forward) execution sequence.

In conjunction with cell highlighting, we’ve added the ability to customize the highlighting
color scheme and font. Select Highlighting in the Settings menu. In the resulting dialog,
you can select highlight background color, text color, and font for the different runtime tables (Text segment,
Data segment, Registers). You can also select them for normal, not just
highlighted, display by even- and odd-numbered row but not by table.

Cool new Labels Window feature: the table can be sorted in either ascending or descending
order based on either the Label (alphanumeric) or the Address (numeric) column. Just click on
the column heading to select and toggle between ascending (upright triangle) or descending
(inverted triangle). Addresses are sorted based on unsigned 32 bit values.
The setting persists across sessions.
The Messages panel, which includes the Mars Messages and Run I/O tabs, now displays using
a mono-spaced (fixed character width) font. This facilitates text-based graphics when running
from the IDE.
The Mars.jar distribution file now contains all files needed to produce
a new jar file. This will make it easier for you to expand the jar, modify source files,
recompile and produce a new jar for local use. CreatMarsJar.bat contains the jar instruction.
The Help window now includes a tab for Acknowledgements. This recognizes MARS contributors
and correspondents.
We’ve added a new system call (syscall) for generating MIDI tones synchronously, syscall 33.
The original MIDI call returns immediately when the tone is generated. The new one will not return
until the tone output is complete regardless of its duration.

The Data Segment display now scrolls 8 rows (half a table) rather than 16 when the
arrow buttons are clicked. This makes it easier to view a sequence of related cells that
happen to cross a table boundary. Note you can hold down either button for rapid scrolling.
The combo box with various data address boundaries also works better now.
Bug Fix: Two corrections to the Keyboard and Display Simulator Tool. Transmitter Ready bit was
not being reset based on instruction count
when running in the kernel text segment, and the Status register’s Exception Level bit was not
tested before enabling the interrupt service routine (could lead to looping if interrupts occur
w/i the interrupt service routine). Thanks to Michael Clancy and Carl Hauser for bringing these
to my attention and suggesting solutions.
Bug Fix: Stack segment byte addresses not on word boundaries were not being processed
correctly. This applies to little-endian byte order (big-endian is not enabled or tested in MARS).
Thanks to Saul Spatz for recognizing the problem and providing a patch.
Minor Bug Fixes include: Correcting a fault leading to failure when launching MARS in command
mode, clarifying assembler error message for too-few or too-many operands error, and correcting the
description of lhu and lbu instructions from “unaligned” to “unsigned”.

Mars 3.5 was released in August 2008. Major enhancements and bug fixes include:

A new Tool, the Keyboard and Display MMIO Simulator, that supports polled and interrupt-driven
input and output operations through Memory-Mapped I/O (MMIO) memory. The MIPS program writes to
memory locations which serve as registers for simulated devices. Supports keyboard input and a
simulated character-oriented display. Click the tool’s Help button for more details.
A new Tool, the Instruction Counter, contributed by MARS user Felipe Lessa. It will count the
number of MIPS instructions executed along with percentages for R-format, I-format, and J-format
instructions. Thanks, Felipe!
Program arguments can now be provided to the MIPS program at runtime, through either an IDE setting or
command mode. See the command mode “pa” option for more details on command mode operation. The argument
count (argc) is placed in $a0 and the address of an array of null-terminated strings containing the
arguments (argv) is placed in $a1. They are also available on the runtime stack ($sp).
Two related changes permit MARS to assemble source code produced by certain compilers such as gcc.
One change is to issue warnings rather than errors for unrecognized directives. MARS implements a
limited number of directives. Ignore these warnings at your risk, but the assembly can continue.
The second change is to allow statement labels to contain, and specifically begin with, ‘$’.
In command mode, final register values are displayed by giving the register name as an option.
Register names begin with ‘$’, which is intercepted by certain OS command shells. The
convention for escaping it is not uniform across shells. We have enhanced the options so now you can
give the register name without the ‘$’. For instance, you can use t0 instead of $t0 as the option.
You cannot refer to registers by number in this manner, since an integer option is interpreted by
the command parser as an instruction execution limit. Thanks to Lucien Chaubert for reporting
this problem.
Minor enhancements: The command mode dump feature has been extended to permit memory address ranges as well
as segment names. If you enter a new file extension into the Open dialog, the extension will remain available throughout
the interactive session. The data segment value repetition operator ‘:’ now
works for all numeric directives (.word, .half, .byte, .float, .double).
This allows you to initialize multiple consecutive memory locations to the same value. For
example:
ones: .half 1 : 8 # Store the value 1 in 8 consecutive halfwords
Major change: Hexadecimal constants containing less than 8 digits will be interpreted as though the
leading digits are 0’s. For instance, 0xFFFF will be interpreted as 0x0000FFFF, not 0xFFFFFFFF as before.
This was causing problems with immediate operands in the range 32768 through 65535, which were
misinterpreted by the logical operations as signed 32 bit values rather than unsigned 16 bit values.
Signed and unsigned 16 bit values are now distinguished by the tokenizer based on the prototype
symbols -100 for signed and 100 for unsigned (mainly logical operations).
Many thanks to Eric Shade of Missouri State University and Greg Gibeling of UC Berkeley for
their extended efforts in helping me address this situation.
Minor Bug Fixes: round.w.s and round.w.d have been modified to correctly perform IEEE
rounding by default. Thanks to Eric Shade for pointing this out.
Syscall 12 (read character) has been changed to leave the character in $v0 rather then $a0. The
original was based on a misprint in Appendix A of Computer Organization and Design.
MARS would not execute from the executable Mars.jar file if it was stored in a directory
path those directory names contain any non-ASCII characters. This has been corrected. Thanks to
Felipe Lessa for pointing this out and offering a solution.
MARS will now correctly detect the EOF condition when reading from a file using syscall 14.
Thanks to David Reimann for bringing this to our attention.

Mars 3.4.1 was released on 23 January 2008. It is a bug fix release to address two bugs.

One bug shows up in pseudo-instructions in which the expansion includes branch instructions. The fixed branch
offsets were no longer correct due to changes in the calculation of branch offsets in Release 3.4.
At the same time, we addressed the issue of expanding such pseudo-instructions when
delayed branching is enabled. Such expansions will now include a nop instruction following the
branch.

We also addressed an off-by-one error that occurred in generating the lui instruction in the
expansion of conditional branch pseudo-instructions whose second operand is a 32 bit immediate.

The expansions for a number of pseudo-instructions were modified to eliminate internal branches.
These and other expansions were also optimized for sign-extended loading of 16-bit immediate operands
by replacing the lui/ori or lui/sra sequence with addi. Pseudo-instructions affected by one
or both of these modifications include: abs, bleu, bgtu, beq, bne, seq, sge, sgeu, sle, sleu, sne,
li, sub and subi. These modifications were suggested by Eric Shade of Missouri State University.

Mars 3.4 was released in January 2008. Major enhancements are:

A new syscall (32) to support pauses of specified length in milliseconds (sleep) during simulated execution.

Five new syscalls (40-44) to support the use of pseudo-random number generators. An unlimited number of these generators are available,
each identified by an integer value, and for each you have the ability to: set the seed value, generate a 32 bit integer value from the Java
int range, generate a 32 bit integer value between 0 (inclusive) and a specified upper bound (exclusive), generate a 32-bit float value between 0 (inclusive) and 1 (exclusive),
and generate a 64-bit double value between 0 (inclusive) and 1 (exclusive). All are based on the java.util.Random class.

Ten new syscalls (50-59) to support message dialog windows and data input dialog windows. The latter are distinguished from
the standard data input syscalls in that a prompting message is specified as a syscall argument and displayed in the input dialog.
All are based on the javax.swing.JOptionPane class.

The capability to dump .text or .data memory contents to file in various formats. The dump can be performed
before or after program execution from either the IDE (File menu and toolbar) or from command mode. It can also be performed
during an execution pause from the IDE. Look for the “Dump Memory” menu item in the File menu, or the “dump” option in command
mode. A .text dump will include only locations containing an instruction. A .data dump will include a multiple
of 4KB “pages” starting at the segment base address and ending with the last 4KB “page” to be referenced by the
program. Current dump formats include pure binary (java.io.PrintStream.write() method), hexadecimal text with one word (32 bits)
per line, and binary text with one word per line. An interface, abstract class, and format loader have been developed to facilitate
development and deployment of additional dump formats. This capability was prototyped by Greg Gibeling of UC Berkeley.

Changed the calculation of branch offsets when Delayed Branching setting is disabled.
Branch instruction target addresses are represented by
the relative number of words to branch. With Release 3.4, this value reflects delayed branching,
regardless of whether the Delayed Branching setting is enabled or not.
The generated binary code for branches will now match that of examples in the Computer Organization
and Design textbook. This is a change from the past, and was made after extensive discussions
with several MARS adopters. Previously, the branch offset was 1 lower if the Delayed Branching setting
was enabled — the instruction label: beq $0,$0,label would generate 0x1000FFFF if
Delayed Branching was enabled and 0x10000000 if it was disabled. Now it will generate 0x1000FFFF in
either case. The simulator will always branch to the correct location; MARS does not allow assembly under one
setting and simulation under the other.

Bug fix: The mars.jar executable JAR file can now be run from a different working directory. Fix was
suggested by Zachary Kurmas of Grand Valley State University.

Bug fix: The problem of MARS hanging while assembling a pseudo-instruction with a label operand that
contains the substring “lab”, has been fixed.

Bug fix: No Swing-related code will be executed when MARS is run in command mode. This fixes a problem that
occurred when MARS was run on a “headless” system (no monitor). Swing is the Java library to support
programming Graphical User Interfaces. Fix was provided by Greg Gibeling of UC Berkeley.

The ‘\0’ character is now recognized when it appears in string literals.

MARS 3.3 was released in July 2007. Major enhancements are:

Support for MIPS delayed branching. All MIPS computers implement this but it can be confusing for
programmers, so it is disabled by default. Under delayed branching, the next instruction after a branch
or jump instruction will always be executed, even if the branch or jump is taken! Many
programmers and assemblers deal with this by inserting a do-nothing “nop” instruction after every branch or jump.
The MARS assembler does not insert a “nop”. Certain pseudo-instructions expand to
a sequence that includes a branch; such instructions will not work correctly under delayed
branching.
Delayed branching is available in command mode with the “db” option.
A new tool of interest mainly to instructors. The Screen Magnifier tool, when selected from
the Tools menu, can be used to produce an enlarged static image of the pixels that lie beneath it.
The image can be annotated by dragging the mouse over it to produce a scribble line. It enlarges
up to 4 times original size.
You now have the ability to set and modify the text editor font family, style and size. Select
“Editor…” from the Settings menu to get the dialog. Click the Apply button to see the new
settings while the dialog is still open. Font settings are retained from one session to the next.
The font family list begins with 6 fonts commonly used across platforms (selected from lists
found at www.codestyle.org), followed by a complete list.
Two of the six are monospaced fonts, two are proportional serif, and two are proportional sans serif.
The Labels window on the Execute pane, which displays symbol table information, has been
enhanced. When you click on a label name or its address, the contents of that address are
centered and highlighted in the Text Segment window or Data Segment window as appropriate. This makes
it easier to set breakpoints based on text labels, or to find the value stored at a label’s address.

If you re-order the columns in the Text Segment window by dragging a column header,
the new ordering will be remembered and applied from that time forward, even from one MARS session to the next. The Text Segment
window is where source code, basic code, binary code, code addresses, and breakpoints are displayed.

If a MIPS program terminates by “running off the bottom” of the program, MARS terminates, as
before, without an exception, but now will display a more descriptive termination message in the
Messages window. Previously, the termination message was the same as that generated after executing an Exit syscall.

A new system call (syscall) to obtain the system time is now available. It is service
30 and is not available in SPIM. Its value is obtained from the java.util.Date.getTime() method.
See the Syscall tab in MIPS help for further information.
A new system call (syscall) to produce simulated MIDI sound through your sound card is now available.
It is service 31 and is not available in SPIM. Its implementation is based on the
javax.sound.midi package. It has been tested only under Windows.
See the Syscall tab in MIPS help for further information.

MARS 3.2.1 was released in January 2007. It is a bug fix release that addresses the
following bug in 3.2: a NullPointerException occurs when MIPS program execution terminates
by “dropping off the bottom” of the program rather than by using one of the Exit system
calls.

MARS 3.2 was released in December 2006. Major enhancements are:

It fixes several minor bugs, including one that
could cause incorrect file sequencing in the Project feature.

It includes the
AbstractMarsToolAndApplication abstract class to serve as a framework for easily
constructing “tools” and equivalent free-standing applications that use the MARS assembler
and simulator engines (kudos to the SIGCSE 2006 audience member who suggested this capability!).
A subclass of this abstract class can be used both ways (tool or application).

The floating
point and data cache tools were elaborated in this release and a new tool for animating and
visualizing memory references was developed. All are AbstractMarsToolAndApplication
subclasses.

This release includes support for exception handlers: the kernel data and text
segments (.kdata and .ktext directives), the MIPS trap-related instructions, and the ability
to automatically include a selected exception (trap) handler with each assemble operation.

Items in the Settings menu became persistent with this release.

Added default assembly file extensions “asm” and “s” to the Config.properties file and used
those not only to filter files for the File Open dialog but also to filter them for the “assemble all”
setting.

Implemented a limit to the amount of text scrollable in the Mars Messages and Run I/O message
tabs – default 1 MB is set in the Config.properties file.

For programmer convenience, labels can now be referenced in the operand field of integer
data directives (.word, .half, .byte). The assembler will substitute the label’s address (low order
half for .half, low order byte for .byte).

For programmer convenience, character literals (e.g. ‘b’, ‘\n’, ‘\377’) can be used anywhere that integer literals are
permitted. The assembler converts them directly to their equivalent 8 bit integer value. Unicode is not supported and
octal values must be exactly 3 digits ranging from ‘\000’ to ‘\377’.

Replaced buttons for selecting Data Segment display base addresses with a combo box and added more
base addresses: MMIO (0xFFFF0000), .kdata (0x90000000), .extern (0x10000000).

MARS 3.1 was released in October 2006. The major issues and features are listed here:

It addressed several minor limits (Tools menu items
could not be run from the JAR file, non-standard shortcuts for Mac users, inflexible and
sometimes inappropriate sizing of
GUI components).

It changed the way SYSCALLs are implemented, to allow anyone to define
new customized syscall services without modifying MARS.

It added a primitive
Project capability through the “Assemble operation applies to all files in current directory.”
setting (also available as “p” option in command mode). The command mode also allows you
to list several file names not necessarily in the same directory to be assembled and linked.

Multi-file assembly also required implementing the “.globl” and “.extern” directives.

And although “Mars tools” are not officially part of MARS releases, MARS 3.1 includes the
initial versions of two tools: one for learning about floating point representation and another
for simulating data caching capability.

MARS 3.0 was released in August 2006, with one bug fix and two major additions.

The bug fix was corrected instruction format for the slti and sltiu instructions.

One major addition is a greatly expanded MIPS-32 instruction
set (trap instructions are the only significant ones to remain unimplemented). This includes, via
pseudo-instructions, all reasonable memory addressing modes for the load/store instructions.

The
second major addition is ability to interactively step “backward” through program execution
one instruction at a time to “undo” execution steps. It will buffer up to 2000 of the most
recent execution steps (this limit is stored in a properties file and can be changed).
It will undo changes made to MIPS memory, registers or condition flags,
but not console or file I/O. This should be a great debugging aid.
It is available anytime execution is paused and at termination (even if terminated due to
exception).

A number of IDE settings, described
above, are now available through the Settings menu.

MARS 2.2 was released in March 2006 with additional bug fixes and implemented command
line options (run MARS from command line with h option for command line help). This also coincides with our
SIGCSE 2006 paper “MARS: An Education-Oriented MIPS Assembly Language Simulator”.

MARS 2.1 was released in October 2005 with some bug fixes.

MARS 2.0 was released in September 2005. It incorporated significant
modifications to both the GUI and the assembler, floating point registers and instructions
most notably.

MARS 1.0 was released in January 2005 and
publicized during a poster presentation at SIGCSE 2005.

Dr. Ken Vollmar initiated MARS development in 2002 at Missouri State University. In
2003, Dr. Pete Sanderson of Otterbein College and his student Jason Bumgarner continued
implementation. Sanderson implemented the assembler and simulator that summer, and
the basic GUI the following summer, 2004.

The development of Releases 3.1 and 3.2 in 2006 and 4.0 in 2010 were supported by the Otterbein College
sabbatical leave program. The development of Release 3.7 during summer 2009 was supported by
a SIGCSE Special Projects Grant.

The MIPS Instruction Set

Correct pronunciation is critical to get the cadence and beat to line
up; see the Pronunciation
Guide at the end of this document for how you should pronounce the various
assembler instructions.

To the tune of: The Major-General’s Song, from
Pirates of Penzance
Inspired by Tom Lehrer’s The Elements

There’s div and nor and mult and or and sllv sra

There’s xor and swl and beq and sll and bgezal jumps today

And multu, srav, and j combined with lhu and lui

And also slt and bne and instruction mthi

There’s sh and sb and lbu and blez and jal and then sltu

And of course there’s and and add and srl and sub and things to do

With the MIPS instructions I am very nimble on my feet

And though I sing assembler but I am really not a geek

There’s addu, ori, slti, swr, and bgez and jalr too

And loads of other fun instructions that were put in just for you

The MIPS instruction set is very simple to be memorized

Which will come in handy when you have your code to optimize!

There’s addi, divu, lh, rfe, and syscall, jr, mfcz

And mfc1, nop, and break, and bltzal with bczt

And srlv, xori, bltz, and lb, lwl, and addiu

andi, subu, lwr, and lwcz, mtcz, sltiu

There’s bczf, bgtz to branch if it’s greater than

And mflo and sw, these instructions are not any also-rans

There’s mtlo and swcz too, although I don’t know what they’re for

And lw – that’s obviously load word from mem bytes there are four

And now my song is through and I know all of my words by the heart

Which will come in handy when we have our projects multi-part

I live and breathe the MIPS instruction set on every night and day

Because the MIPS assembler will always try and work my way!

They are described in the table below. MIPS register contents are not affected by a system call, except for result registers as specified in the table below. How to use SYSCALL system services Step 1. Load the service number in register $v0. Step 2. Load argument values, if any, in $a0, $a1, $a2, or $f12 as specified. Step 3. Issue the SYSCALL instruction. Step 4. Retrieve return values, if any, from result registers as specified. Example: display the value stored in $t0 on the console li $v0, 1 # service 1 is print integer add $a0, $t0, $zero # load desired value into argument register $a0, using pseudo-op syscall Table of Available Services Service Code in $v0 Arguments Result print integer 1 $a0 = integer to print   print float 2 $f12 = float to print   print double 3 $f12 = double to print   print string 4 $a0 = address of null-terminated string to print   read integer 5   $v0 contains integer read read float 6   $f0 contains float read read double 7   $f0 contains double read read string 8 $a0 = address of input buffer $a1 = maximum number of characters to read See note below table sbrk (allocate heap memory) 9 $a0 = number of bytes to allocate $v0 contains address of allocated memory exit (terminate execution) 10     print character 11 $a0 = character to print See note below table read character 12   $v0 contains character read open file 13 $a0 = address of null-terminated string containing filename $a1 = flags $a2 = mode $v0 contains file descriptor (negative if error). See note below table read from file 14 $a0 = file descriptor $a1 = address of input buffer $a2 = maximum number of characters to read $v0 contains number of characters read (0 if end-of-file, negative if error). See note below table write to file 15 $a0 = file descriptor $a1 = address of output buffer $a2 = number of characters to write $v0 contains number of characters written (negative if error). See note below table close file 16 $a0 = file descriptor   exit2 (terminate with value) 17 $a0 = termination result See note below table Services 1 through 17 are compatible with the SPIM simulator, other than Open File (13) as described in the Notes below the table. Services 30 and higher are exclusive to MARS. time (system time) 30   $a0 = low order 32 bits of system time $a1 = high order 32 bits of system time. See note below table MIDI out 31 $a0 = pitch (0-127) $a1 = duration in milliseconds $a2 = instrument (0-127) $a3 = volume (0-127) Generate tone and return immediately. See note below table sleep 32 $a0 = the length of time to sleep in milliseconds. Causes the MARS Java thread to sleep for (at least) the specified number of milliseconds. This timing will not be precise, as the Java implementation will add some overhead. MIDI out synchronous 33 $a0 = pitch (0-127) $a1 = duration in milliseconds $a2 = instrument (0-127) $a3 = volume (0-127) Generate tone and return upon tone completion. See note below table print integer in hexadecimal 34 $a0 = integer to print Displayed value is 8 hexadecimal digits, left-padding with zeroes if necessary. print integer in binary 35 $a0 = integer to print Displayed value is 32 bits, left-padding with zeroes if necessary. print integer as unsigned 36 $a0 = integer to print Displayed as unsigned decimal value. (not used) 37-39     set seed 40 $a0 = i.d. of pseudorandom number generator (any int). $a1 = seed for corresponding pseudorandom number generator. No values are returned. Sets the seed of the corresponding underlying Java pseudorandom number generator (java.util.Random). See note below table random int 41 $a0 = i.d. of pseudorandom number generator (any int). $a0 contains the next pseudorandom, uniformly distributed int value from this random number generator's sequence. See note below table random int range 42 $a0 = i.d. of pseudorandom number generator (any int). $a1 = upper bound of range of returned values. $a0 contains pseudorandom, uniformly distributed int value in the range 0 See note below table random float 43 $a0 = i.d. of pseudorandom number generator (any int). $f0 contains the next pseudorandom, uniformly distributed float value in the range 0.0 See note below table random double 44 $a0 = i.d. of pseudorandom number generator (any int). $f0 contains the next pseudorandom, uniformly distributed double value in the range 0.0 See note below table (not used) 45-49     ConfirmDialog 50 $a0 = address of null-terminated string that is the message to user $a0 contains value of user-chosen option 0: Yes 1: No 2: Cancel InputDialogInt 51 $a0 = address of null-terminated string that is the message to user $a0 contains int read $a1 contains status value 0: OK status -1: input data cannot be correctly parsed -2: Cancel was chosen -3: OK was chosen but no data had been input into field InputDialogFloat 52 $a0 = address of null-terminated string that is the message to user $f0 contains float read $a1 contains status value 0: OK status -1: input data cannot be correctly parsed -2: Cancel was chosen -3: OK was chosen but no data had been input into field InputDialogDouble 53 $a0 = address of null-terminated string that is the message to user $f0 contains double read $a1 contains status value 0: OK status -1: input data cannot be correctly parsed -2: Cancel was chosen -3: OK was chosen but no data had been input into field InputDialogString 54 $a0 = address of null-terminated string that is the message to user $a1 = address of input buffer $a2 = maximum number of characters to read See Service 8 note below table $a1 contains status value 0: OK status. Buffer contains the input string. -2: Cancel was chosen. No change to buffer. -3: OK was chosen but no data had been input into field. No change to buffer. -4: length of the input string exceeded the specified maximum. Buffer contains the maximum allowable input string plus a terminating null. MessageDialog 55 $a0 = address of null-terminated string that is the message to user $a1 = the type of message to be displayed: 0: error message, indicated by Error icon 1: information message, indicated by Information icon 2: warning message, indicated by Warning icon 3: question message, indicated by Question icon other: plain message (no icon displayed) N/A MessageDialogInt 56 $a0 = address of null-terminated string that is an information-type message to user $a1 = int value to display in string form after the first string N/A MessageDialogFloat 57 $a0 = address of null-terminated string that is an information-type message to user $f12 = float value to display in string form after the first string N/A MessageDialogDouble 58 $a0 = address of null-terminated string that is an information-type message to user $f12 = double value to display in string form after the first string N/A MessageDialogString 59 $a0 = address of null-terminated string that is an information-type message to user $a1 = address of null-terminated string to display after the first string N/A NOTES: Services numbered 30 and higher are not provided by SPIM Service 8 - Follows semantics of UNIX 'fgets'. For specified length n, string can be no longer than n-1. If less than that, adds newline to end. In either case, then pads with null byte If n = 1, input is ignored and null byte placed at buffer address. If n < 1, input is ignored and nothing is written to the buffer. Service 11 - Prints ASCII character corresponding to contents of low-order byte. Service 13 - MARS implements three flag values: 0 for read-only, 1 for write-only with create, and 9 for write-only with create and append. It ignores mode. The returned file descriptor will be negative if the operation failed. The underlying file I/O implementation uses java.io.FileInputStream.read() to read and java.io.FileOutputStream.write() to write. MARS maintains file descriptors internally and allocates them starting with 3. File descriptors 0, 1 and 2 are always open for: reading from standard input, writing to standard output, and writing to standard error, respectively (new in release 4.3). Services 13,14,15 - In MARS 3.7, the result register was changed to $v0 for SPIM compatability. It was previously $a0 as erroneously printed in Appendix B of Computer Organization and Design,. Service 17 - If the MIPS program is run under control of the MARS graphical interface (GUI), the exit code in $a0 is ignored. Service 30 - System time comes from java.util.Date.getTime() as milliseconds since 1 January 1970. Services 31,33 - Simulate MIDI output through sound card. Details below. Services 40-44 use underlying Java pseudorandom number generators provided by the java.util.Random class. Each stream (identified by $a0 contents) is modeled by a different Random object. There are no default seed values, so use the Set Seed service (40) if replicated random sequences are desired. Example of File I/O The sample MIPS program below will open a new file for writing, write text to it from a memory buffer, then close it. The file will be created in the directory in which MARS was run. # Sample MIPS program that writes to a new file. # by Kenneth Vollmar and Pete Sanderson .data fout: .asciiz "testout.txt" # filename for output buffer: .asciiz "The quick brown fox jumps over the lazy dog." .text ############################################################### # Open (for writing) a file that does not exist li $v0, 13 # system call for open file la $a0, fout # output file name li $a1, 1 # Open for writing (flags are 0: read, 1: write) li $a2, 0 # mode is ignored syscall # open a file (file descriptor returned in $v0) move $s6, $v0 # save the file descriptor ############################################################### # Write to file just opened li $v0, 15 # system call for write to file move $a0, $s6 # file descriptor la $a1, buffer # address of buffer from which to write li $a2, 44 # hardcoded buffer length syscall # write to file ############################################################### # Close the file li $v0, 16 # system call for close file move $a0, $s6 # file descriptor to close syscall # close file ############################################################### Using SYSCALL system services 31 and 33: MIDI output These system services are unique to MARS, and provide a means of producing sound. MIDI output is simulated by your system sound card, and the simulation is provided by the javax.sound.midi package. Service 31 will generate the tone then immediately return. Service 33 will generate the tone then sleep for the tone's duration before returning. Thus it essentially combines services 31 and 32. This service requires four parameters as follows: pitch ($a0) Accepts a positive byte value (0-127) that denotes a pitch as it would be represented in MIDI Each number is one semitone / half-step in the chromatic scale. 0 represents a very low C and 127 represents a very high G (a standard 88 key piano begins at 9-A and ends at 108-C). If the parameter value is outside this range, it applies a default value 60 which is the same as middle C on a piano. From middle C, all other pitches in the octave are as follows: 61 = C# or Db 62 = D 63 = D# or Eb 64 = E or Fb 65 = E# or F 66 = F# or Gb 67 = G 68 = G# or Ab 69 = A 70 = A# or Bb 71 = B or Cb 72 = B# or C To produce these pitches in other octaves, add or subtract multiples of 12. duration in milliseconds ($a1) Accepts a positive integer value that is the length of the tone in milliseconds. If the parameter value is negative, it applies a default value of one second (1000 milliseconds). instrument ($a2) Accepts a positive byte value (0-127) that denotes the General MIDI "patch" used to play the tone. If the parameter is outside this range, it applies a default value 0 which is an Acoustic Grand Piano. General MIDI standardizes the number associated with each possible instrument (often referred to as program change numbers), however it does not determine how the tone will sound. This is determined by the synthesizer that is producing the sound. Thus a Tuba (patch 58) on one computer may sound different than that same patch on another computer. The 128 available patches are divided into instrument families of 8: 0-7 Piano 64-71 Reed 8-15 Chromatic Percussion 72-79 Pipe 16-23 Organ 80-87 Synth Lead 24-31 Guitar 88-95 Synth Pad 32-39 Bass 96-103 Synth Effects 40-47 Strings 104-111 Ethnic 48-55 Ensemble 112-119 Percussion 56-63 Brass 120-127 Sound Effects Note that outside of Java, General MIDI usually refers to patches 1-128. When referring to a list of General MIDI patches, 1 must be subtracted to play the correct patch. For a full list of General MIDI instruments, see www.midi.org/about-midi/gm/gm1sound.shtml. The General MIDI channel 10 percussion key map is not relevant to the toneGenerator method because it always defaults to MIDI channel 1. volume ($a3) Accepts a positive byte value (0-127) where 127 is the loudest and 0 is silent. This value denotes MIDI velocity which refers to the initial attack of the tone. If the parameter value is outside this range, it applies a default value 100. MIDI velocity measures how hard a note on (or note off) message is played, perhaps on a MIDI controller like a keyboard. Most MIDI synthesizers will translate this into volume on a logarithmic scale in which the difference in amplitude decreases as the velocity value increases. Note that velocity value on more sophisticated synthesizers can also affect the timbre of the tone (as most instruments sound different when they are played louder or softer). System service 31 was developed and documented by Otterbein student Tony Brock in July 2007. MARS Acknowledgements MARS Acknowledgements Updated 18 August 2014 Pete and Ken would like to acknowledge the many helpful contributors to MARS. It has succeeded beyond our wildest expectations and for this we are most grateful. Its success would not be possible without your feedback, suggestions and assistance! We are pleased to recognize these contributions to release 4.5: Torsten Mahne, Umberto Villano and others who took care of the bug with certain European keyboards that require an Alt key combo to form essential MIPS assembly characters like $ and #. I had no means of testing it. Eric Wang at Washington State University, who suggested adding cursor positioning to the Keyboard and Display MMIO Simulator tool. Marcio Roberto and everyone else involved in the development of MIPS X-Ray tool, which has been around for several years but only now added to the release. Sorry for the delay. We also appreciate the contributions others have made to previous releases: Carl Burch of Hendrix College, who developed the mechanism for simulating the execution of straight binary code. Previously, execution was based on ProgramStatement objects generated by the assembler. This, combined with the added capabilities to write to the text segment and branch/jump into the data segment at runtime, permits one to produce self-modifying programs, simulate buffer overflow attacks, and the like. Tom Bradford, Slava Pestov and others, who developed the jEdit Syntax Package (syntax.jedit.org) at the heart of the syntax-aware color highlighting editor. It was old but the licensing was right and it was written for embedding into Java applications. Mohammad Sekhavat from Sharif University in Tehran, who developed the macro capability. Greg Gibeling of UC Berkeley, who introduced capabilities into his customized version of MARS that have subsequently been expanded and integrated into our release. These include the ability to dump MIPS memory contents to file and parser improvements to distinguish signed from unsigned hexadecimal constants. Eric Shade of Missouri State University, who suggested several improvements to pseudo-instruction expansions such as elimination of internal branches and improvements to the sign-extended loading of 16-bit immediate operands. Saul Spatz of the University of Missouri Kansas City, who noticed and provided a solution for a flaw in the calculation of byte-oriented addresses in the simulated MIPS memory stack segment. He has also suggested several improvements that we have implemented. Zachary Kurmas of Grand Valley State University, who suggested several bug fixes and who encorporated MARS into his own successful JLSCircuitTester digital logic simulator software. Felipe Lessa, who contributed the Instruction Counter tool and suggested a solution for the problem of MARS inability to launch when stored in a directory whose name contained non-ASCII characters. Carl Hauser of Washington State University, who pointed out and provided a solution to a flaw in the Keyboard and Display Simulator Tool in how it used the Exception Level bit in the Coprocessor1 Status register. Also thanks to Michael Clancy of UC Berkeley for pointing out a flaw in the tool's mechanism for resetting the Transmit Ready bit when operating in kernel memory. Dave Poplawski of Michigan Technological University, for his assistance in working through some issues with signed/unsigned constants and with output redirection. Ingo Kofler of Klagenfurt University in Austria, who contributed two Tools: a tool to collect Instruction Statistics, and a tool to simulate branch prediction with a Branch History Table. Brad Richards and Steven Canfield from the University of Puget Sound, for providing a technique that improved file loading performance. Jan Schejbal and Jan-Peter Kleinhans of Darmstadt technical university in Germany, for suggesting and providing a patch to display Run I/O text in a constant-width font. Max Hailperin of Gustavus Adolphus College, who made several improvements to the MIDI syscalls. David Patterson of UC Berkeley, for making time in his busy schedule for Ken's demo of MARS. Denise Penrose and Nate McFadden of Morgan Kaufmann Publishers, for their assistance as editors of Computer Organization and Design. Ricardo Pascual of University of Murcia in Spain, who contributed the code to permit input syscall keystrokes to be typed directly into the Run I/O window instead of through a popup dialog. Didier Teifreto of Université de Franche-Comté in France, who contributed the Digital Lab Sim tool. Facundo Agriel of the University of Illinois at Chicago, who added font selection to the Keyboard and Display Simulator tool. Patrik Lundin for contributing the code to add scrolling to the keyboard and display simulator. Otterbein students Robert Anderson, Jonathan Barnes, Sean Pomeroy and Melissa Tress for contributing the new command-mode options for specifying MARS exit codes when assembly or simulation errors occur. This was sparked by a comment from Zheming Jim of the University of South Carolina. The unknown audience member at our SIGCSE 2006 conference presentation, who suggested that MARS would also be useful running in the background in support of an external application. This led directly to our development of the Tools framework and API that truly distinguishes MARS from all other MIPS simulators. We would also like to recognize many others who have contacted us to point out bugs, suggest improvements, or engaged us in interesting correspondence. The bugs have been addressed and the improvements either implemented or added to our wish list.

It is followed by a tab-separated list of basic instruction # templates to complete and substitute for the pseudo-op. # Format for specifying syntax of templates is different from specifying syntax of source statement: # (n=0,1,2,3,...) is token position in source statement (operator is token 0, parentheses are tokens but commas aren't) # RGn means substitute register found in n'th token of source statement # NRn means substitute next higher register than the one in n'th token of source code # OPn means substitute n'th token of source code as is # LLn means substitute low order 16-bits from label address in source token n. # LLnU means substitute low order 16-bits (unsigned) from label address in source token n. # LLnPm (m=1,2,3,4) means substitute low order 16-bits from label address in source token n, after adding m. # LHn means substitute high order 16-bits from label address in source token n. Must add 1 if address bit 15 is 1. # LHnPm (m=1,2,3,4) means substitute high order 16-bits from label address in source token n, after adding m. Must then add 1 if bit 15 is 1. # VLn means substitute low order 16-bits from 32-bit value in source token n. # VLnU means substitute low order 16-bits (unsigned) from 32-bit value in source token n. # VLnPm (m=1,2,3,4) means substitute low order 16-bits from 32-bit value in source token n, after adding m to value. # VLnPmU (m=1,2,3,4) means substitute low order 16-bits(unsigned) from 32-bit value in source token n, after adding m to value. # VHLn means substitute high order 16-bits from 32-bit value in source token n. Use this if later combined with low order 16-bits using "ori $1,$1,VLnU". See logical and branch operations. # VHn means substitute high order 16-bits from 32-bit value in source token n, then add 1 if value's bit 15 is 1. Use this only if later instruction uses VLn($1) to calculate 32-bit address. See loads and stores. # VHLnPm (m=1,2,3,4) means substitute high order 16-bits from 32-bit value in source token n, after adding m. See VHLn. # VHnPm (m=1,2,3,4) means substitute high order 16-bits from 32-bit value in source token n, after adding m. Must then add 1 if bit 15 is 1. See VHn. # LLP is similar to LLn, but is needed for "label+100000" address offset. Immediate is added before taking low order 16. # LLPU is similar to LLn, but is needed for "label+100000" address offset. Immediate is added before taking low order 16 (unsigned). # LLPPm (m=1,2,3,4) is similar to LLP except m is added along with immediate before taking low order 16. # LHPA is similar to LHn, but is needed for "label+100000" address offset. Immediate is added before taking high order 16. # LHPN is similar to LHPA, used only by "la" instruction. Address resolved by "ori" so do not add 1 if bit 15 is 1. # LHPAPm (m=1,2,3,4) is similar to LHPA except value m is added along with immediate before taking high order 16. # LHL means substitute high order 16-bits from label address in token 2 of "la" (load address) source statement. # LAB means substitute textual label from last token of source statement. Used for various branches. # S32 means substitute the result of subtracting the constant value in last token from 32. Used by "ror", "rol". # DBNOP means Delayed Branching NOP - generate a "nop" instruction but only if delayed branching is enabled. Added in 3.4.1 release. # BROFFnm means substitute n if delayed branching is NOT enabled otherwise substitute m. n and m are single digit numbers indicating constant branch offset (in words). Added in 3.4.1 release. # COMPACT is a marker to separate the default template from a second template optimized for 16-bit addresses. See loads and stores having (data) label operands. # Everything else is copied as is into the generated statement (you must use register numbers not mnemonics) # The list of basic instruction templates is optionally followed a description of the instruction for help purposes. # To add optional description, append a tab then the '#' character followed immediately (no spaces) by the description. # # See documentation for ExtendedInstruction.makeTemplateSubstitutions() for more details. # # Matching for a given instruction mnemonic is first-fit not best-fit. If an instruction has both 16 and 32-bit # immediate operand options, they should be listed in that order (16-bit version first). Otherwise the 16-bit # version will never be matched since the 32-bit version fits small immediate values first. # # The pseudo-op specification must start in the first column. If first column is blank, the line will be skipped! # # When specifying the example instruction (first item on line), the conventions I follow are: # - for a register operand, specify a numbered register (e.g. $t1 or $f1) to represent any register in the set. # The numerical value is not significant. This is NOT the case when writing the templates that follow! # In the templates, numbered registers are parsed as is (use only $0 and $1, which are $zero and $at). # - for an immediate operand, specify a positive value indicative of the expected range. I use 10 to represent # a 5 bit value, 100 to represent a 16-bit value, and 100000 to represent a 32-bit value. # - for a label operand, I use the string "label" (without the quotes). # The idea is to give the parser an example that will be parsed into the desired token sequence. Syntax checking # is done by comparing the source token sequence to list of token sequences generated from the examples. # IMPORTANT NOTE: The use of $t1,$t2, etc in the instruction sample means that any CPU register reference # can be used in that position. It is simply a placeholder. By contrast, when # $1 is used in the template specification, $1 ($at) is literally placed into the generated # instruction! If you want the generated code to echo the source register, use RG1,RG2, etc. ####################### arithmetic and branch pseudo-ops ##################### not $t1,$t2 nor RG1, RG2, $0 #Bitwise NOT (bit inversion) # Here are some "convenience" arithmetic pseduo-ops.

All the them require assembler to add a constant # byte offset (from 1 to 4 bytes) to the given or calculated address. # NOTE: I have abandoned the "accepted" expansion of immed16($reg) addressing form for the # unaligned and double load/store pseudo-instructions because they produce what I consider # incorrect results for immediate values at the upper edge of the signed 16-bit range # (32765 through 32767). The expansion of these pseudo's requires adding an additional # byte offset (from 1 to 4 bytes) to the immediate value, which overflows the signed 16 # bit range and results in a large negative offset with no counterbalancing increment # to the high order 16-bits. Thus if the two pieces of unaligned data end up in different # words, they are stored 64K bytes apart! For example, the normal expansion of # "usw $8,32767($9)" would be "swl $8,-32766($9)", "swr $8, 32767($9)" Both SPIM and # Britten's text do this but I consider it incorrect. My compromise is the following: # since each of the expansion calls for two calculated offsets, one of which can possibly # overflow due to the addition but the other will not (because there is no addition), # I'll code the expansion to treat the at-risk calculated offset as 32-bits (it will generate # the lui and addu, which is unnecessary in almost every case but is always correct) # and the second as 16-bits.
