1. (40 points) Assume we have a 128KB8-way associative cache, with 32B blocks a) What is the set number we are accessing for virtual address 0081D56C ? b) What is the set number and the tag if the for virtual access in part a if cache is 2-way associative? c) Repeat b for direct mapped cache. d) What is the effect - between part a to part c - (i.e. when reducing associativity) on following metrics: miss rate, and hit time
