Question 2: Cache A block-set-associative cache consists of a total of 64 blocks, divided into 4-block sets The main memory contains 4096 blocks, each consisting of 32 words. Assuming a 32-bit byte-addressable address space, how many bits are there in each of the Tag, Set, and Word fields? a. A computer has two cache levels L1 and L2. Plot two graphs for the average memory access time (y-axis) versus hit rate h1 (x-axis) for the two values h2 0.75 and h2 0.85. Use the values 0.90, 0.92, 0.94, and 0.96, for hi . Assume that the miss penalties are 1 5 and 100 for the L1 and L2 caches, respectively, where is the access time of the L1 caches b
