Question

Here is a series of address references given as word addresses: 2, 3, 11, 16, 21, 13, 64, 48, 19, 11, 3, 22, 4, 27, 6, and 11. Assuming a direct-mapped cache with 16 one-word blocks that is initially empty, label each reference in the list as a hit or a miss and show the final contents of the cache. Cache Cl is direct mapped with 16 one-word blocks. Cache C2 is direct mapped with 4 four-word blocks. Assume that the miss penalty for Cl is 8 memory bus clock cycles and the miss penalty for C2 is 11 memory bus clock cycles. Assuming that the caches are initially empty, find a reference string for which C2 has a lower miss rate but spends more memory bus clock cycles on cache misses than Cl. Use word addresses.
