MIPS Architecture Simulator Project Assignment

Project Overview

Design and implement a simulator for a subset of the MIPS $32-$bit architecture. This project will help you understand computer architecture concepts, instruction set architecture, and system simulation.

Required Functionality

$1.$ Instruction Set Support

Implement the following MIPS instructions:

R$-$Format

add rd$,$ rs$,$ rt

sub rd$,$ rs$,$ rt

and rd$,$ rs$,$ rt

or rd$,$ rs$,$ rt

slt rd$,$ rs$,$ rt

sll rd$,$ rt$,$ shamt

srl rd$,$ rt$,$ shamt

I$-$Format

addi rt$,$ rs$,$ imm

lw rt$,$ offset$($rs$)$

sw rt$,$ offset$($rs$)$

beq rs$,$ rt$,$ label

bne rs$,$ rt$,$ label

J$-$Format

j target

jal target

jr rs

$2.$ Core Features

$32-$bit instruction handling

$32$ general$-$purpose registers

Program counter management

Memory management $($minimum $512$ Bytes for IM$,512$ Bytes for DM$)$

Instruction fetch$-$decode$-$execute cycle

Support assembly code instruction input

$3.$ User Interface Requirements

Command$-$line interface for loading and executing programs

Step$-$by$-$step execution mode

Register state display

Memory state display

Program execution trace capability
