5.20 In this exercise, we will examine how replacement policies affect miss rate. Assume a two-way set associative cache with four one-word blocks. Consider the following word address sequence: 0, 1,2,3, 4,2,3,4,5,6,7,0, 1,2,3,4,5,6,7,0 Consider the following address sequence: 0, 2,4,8, 10, 12, 14, 16, a) Assuming an LRU replacement policy, which accesses are hits? b) Assuming an MRU (most recently used) replacement policy, which accesses are hits
