[Solved] Ve370 Introduction to Computer Organization Lab 4 Pipelined Processor

Purpose

This lab is intended to help you better understand the concepts of pipelined architecture as well as how different instructions are executed by a pipelined processor. For simplicity purpose, we assume the hazard problems are all resolved by stalls in software, so your modeled hardware doesnt have to worry about hazards.

Tasks

This lab is similar to and based on the single-cycle processor lab, except you will model a pipelined processor in Verilog HDL that executes a bigger subset of RISC-V instructions including:

• The arithmetic-logical instructions add, addi, sub, and, andi, or, sll, slli, srl, srli, and sra
• The memory-reference instructions lw, sw, lb, lbu, and sb
• The jumping instructions beq, bne, bge, blt, jal, and jalr

Your modules must be simulated with a Verilog simulator and synthesized by using Xilinx synthesis tool. A simple RISC-V assembly testing program without any hazard will be provided to verify that your processor can execute those instructions continuously and correctly.

FPGA implementation is NOT required for this lab.

Team Organization

This lab is a team effort. Each team should consist of 3 students, randomly grouped. The work should be appropriately divided and distributed among all team members. Students are not allowed to switch teams without permission of the instructor.

Deliverables

• Demonstration Every team should demonstrate to the teaching group the following before your lab session ends:
  • Simulation results of the top-module of your design
  • RTL schematic of your Verilog design generated with Xilinx Vivado software.

Each team member should be prepared for an oral exam on this lab during the demonstration.

• Lab report The lab report should be a written report including:
  • Brief description of all aspects of the modeling and implementation of the processor;
  • Screen shots and brief explanations of simulation results for each of the instructions: add, addi, lw, sw, beq, and jal.
  • RTL schematic of your Verilog model generated with Xilinx Vivado software;

• Peer Evaluation Each team member is required to provide a peer evaluation for the team effort in this lab. The marks of the peer evaluation should be integers ranging between 0 to 10, inclusively, with 10 indicating the biggest contribution. A mark should be given to each team

member including yourself according the team members contribution based on your observation. A brief description of contribution of each team member should also be provided, as shown in the following table.

• Source Files All your Verilog source files and any other supporting files should be submitted as appendix to the lab report.
