CPRE 305 Final Project Testing and Grading Guideline

The weight of testing is 70% in your grade for the final project, and the weight of report is 30%. You may get up to 10% extra credit as discussed below.

· You may want to test your MIPS pipeline with each implemented instruction in your instruction set before other tests.

· You should design a number of code sequences to test different aspects of your pipeline implementation, at least including:

• Pipelined execution of independent instructions
• Data forwarding from MEM stage to EX stage and from WB stage to EX stage
• Data hazard detection and pipeline stall at ID stage

· Depending on your implementation, you may also test one or more of the following aspects:

· Early branch decision at ID stage

· Additional data forwarding for the early branch decision

· Instruction flushing for taken branches (at IF stage with early branch decision at ID stage); or

· Delayed branch slot

If you have any questions on above descriptions, be sure to ask the instructor or TAs for explanations.

· Test your implementation with the provided program test1. This program consists of five types of instructions: LW, SW, ADD, SUB, and BEQ.

• The program tests all major aspects of MIPS pipeline implementation
• If the test is successful, you may get the full credit of the testing.

· Extra credit (10%): Extend your implementation to run the two programs you wrote for HW8.

· The extension may involve significant extra work.

· Your testing must be convincible.

· You need to include your tests in your report.

· Your report should include the ISA you designed for HW8 even if not all instructions are tested.
