Introduction Pipeline is one of the basic techniques to improve the CPU's performance. It simulates the execution of a subset of 32-bit 5-stage MIPS CPU pipeline described in your textbook; "Computer Organization and Design (COD)" by Patterson & Hennessy. Recently I got an assignment that requires that I create a program that emulates a MIPS machine in Java, C, or C++. Outline of Lab • Write a simulator for the MIPS five-stage pipeline (covered in ECE 232) that does the following: • Implements a subset of the instruction set (LW, SW, BEQ, ADD, SUB, MUL, ADDI) • Reads from a file an assembly language program • Simulates, cycle by cycle, the activity in all registers associated with that program. It can be used to run and debug M. In part 1, I presented the instruction set of the pipelined MIPS processor and partially provided the Verilog code for the single-cycle MIPS datapath as shown below. Building MIPS binary code To test your program we need to generate binary machine code to load into your memory module. The pipeline of the MIPS R4000 is a good example. We have provided pipeline register data structures specified in the file, mips-small-pipe. Only 1 memory. In SimuMIPS, we fol-low the same design patterns as described in the Patterson. 24, includes the jump instruction.
