ECE 510: Foundations of Computer Engineering
Project 3

This assignment will give you experience in programming in C++ and the operation of a MIPS
pipelined processor. Further, you will gain insight into how multiple events that occur in parallel
can be simulated using a sequential machine.
1. Problem Statement
This assignment requires a simple 5 stage pipelined machine to be simulated. The simulator
should be capable of implementing the MIPS architecture on a cycle by cycle basis. The simulator
must be cycle accurate with respect to contents of the registers, but need not be faithful to other
hardware details such as control signals. The output of the simulator, in addition to the register
contents and latch values should include the utilization factor of each functional unit and the
total time in cycles to execute a set of instructions. Implement the simulator according to the
specifications described below in C++. Submit the code, simulation results and a project
description write-up.
1.1 Instructions to be implemented
The simulator should implement the following instructions: add, sub, addi, mul, lw, sw, beq, lui,
and, andi, or, ori, sll, srl, slti, and sltiu. Note that these instructions operate integer instructions
only. The MIPS instruction format can be used for all instructions except mul. Assume the syntax
for mul is mul $a,$b,$c, meaning that we multiply the contents of $b and $c, the least significant
32 bits of results are placed in register $a and the most significant 32-bits of the result will be
stored in register $(a+1). For example, mul $t0, $t8, $t9 will store lower 32-bits of the product of
$t8 * $t9 in register $t0 and the upper 32-bits of the product in register $t1 (Hint: See MIPS green
sheet instructions summary for registers numbering). This is different from the mult instruction
in MIPS. Assume the opcode and function code for mul to be same as that of mult.
1.3 Memory, Registers and PC
The memory is one word wide and 2K bytes in size. There are physically separate instruction and
data memories for the instruction and data. Data memory is initialized to 0 at the beginning of
each simulation run. There is no cache in this machine.
There are 32 registers; register 0 is hardwired to 0. In addition, there is a Program Counter (PC).
PC should start execution by fetching the instruction stored in the location to which it is
