Software
The software we use to run the MIPS assembly program is called MARS (MIPS Assembler and Runtime Simulator). You can download it here.
Program Skeleton
You MUST use the following code to work on your project.
# ELEC2350 (2020/21 Fall) – Introduction to Computer Organization and Design # Midterm Project
.data
# Your Student ID is 12346789. It is randomly stored into array “stdid”
stdid: .word 67891234
msg0: .asciiz”Enterthepatternsize(from1to10):” nline: .asciiz “\n”
spc: .asciiz ” ”
.text main:
# Print the string “Enter the pattern size (from 1 to 10):” to the MARS I/O console
la $a0, msg0 li $v0, 4 syscall
# Read and save user input from the MARS I/O console into register $v0
li $v0, 5
syscall
# ——————————————————————– #
# Write your code here #
# ——————————————————————–
# Terminate the program
li $v0, 10 syscall
How to use SYSCALL functions in MARS
SYSCALL (or syscall) allows you to handle inputs and outputs in the MARS I/O console (e.g. read an integer, print an integer, print a string, etc.). Please read this page for details.
