a pipelining problem that you will need to state how many cycles it takes to execute the program with and without a 4-stage pipeline; a cache problem where you need to determine how many cycles it takes to execute the program with and without a cache. Pick a loop optimization and a straight line code
CSc 656 Project 2: Cache simulation due Monday 4/19/2021, 3pm (standard 48-hour grace period for 75% credit) (9% of your grade) This is an individual project. Work on your own. For this project, you will write a cache simulator that uses memory address traces as input. The traces can be found on iLearn in the
