Chapter 5 Memory Hierarchy part 3 Virtual Memory 1 Virtual memory • Main memory acting as a “cache” for hard disk (usually magnetic disks) • Two major motivations for Virtual Memory: 1. Allowefficientandsafesharingamongmultipleprograms 2. Removestheprogrammingburdensofasmallmemory Different terminologies but same concepts cache vs. virtual memory block vs. page cache miss vs. page fault Virtual addresses Physical
Chapter 3 Arithmetic for Computers 1 Numbers • Bits are just bits — conventions define relationship between bits and numbers • Binary numbers (base 2) 0000 0001 0010 0011 0100 0101 0110 0111 1000 1001… decimal: 0…2n-1 • Of course it gets more complicated: numbers are finite (overflow) fractions and real numbers negative numbers e.g.,

Chapter 4 part 2 Processor (Datapath and Control) Pipelining 1 Pipelining • Implementation technique in which multiple instructions are overlapped in execution, like assembly line • Suppose there are only one washer, one dryer, one “folder”, and “storer”. If there are 20 people lined up for the laundry, how faster the second one is than

Assignment Outline This Assignment is split into 2 parts, Part A and Part B. The objective of Part A is to get you familiar with the synthesised MIPS single cycle processor and to write some simple programs to control the processor. Part B requires you to extend the processor so that it will implement additional

Topic Assignment Instructions The topic for the term project this semester is to develop a mini-disassembler for MIPS-32 ISA. Note that this is an extension to homework 3. Optional: you can work with another student in the class on this term project. If you work with another student EACH OF YOU must submit a ZIP
