Project-2 R-Type MIPS

Computer Organization
In this project, you will use Altera Quartus II with Verilog. You will design a part of the 32-bit MIPS
processor. The block that you will design will get an 32-bit instruction as its input and compute the
resultant value and stores it to the destination register given by the instruction. The supported
instructions in your design will be add, sub, and, or, sra, srl, sll, sllv and slt instructions. The input of
your top-module will be the instruction only. The output of your top-module will be the output of
your ALU to follow and check its computations during the simulation. You will write the memory
contents before and after the execution of instructions using writememh in your testbench verilog
code. You will initialize memory contents using readmemh.
1. You will design ALU module using only structural Verilog with assign statement. (So you cannot
use always, initial, if, case statements.)
2. You will design Register module using behavioral Verilog. The register has 32 registers each
containing 32-bit number.
3. You will write a top-level Verilog module to connect ALU and Register modules accurately to
finish the project.
4. You will write a working testbench and simulate your design by ModelSim as you learnt in the
PS.The project will be explained in detail in the PS. But do not wait until the PS to start the project. If
you did not understand – sorry, if you understood but want to understand better – feel free to
ask. Attend this PS, it is a must.
Please be sure that your design simulates correctly. Designs that are not even simulating can get at
most 25 points.
Submit your Altera Project folder as a zip file to Moodle. We will simulate your design using not
only your testbench but also our testbench to see whether all instructions are executing correctly
or not.
No late submissions even if it is 5 minutes. No medical reports. No excuses. No cry. So start early.
The “best” projects will have an opportunity to upload their designs to a FPGA board and we will
execute it in class. What we mean by “best” will be explained in this week’s PS.
