Problem
Consider a cache (M1) and memory (M2) hierarchy with the following characteristics: M: 64K words, 5 ns access time M2: 4M words, 40 ns access time Assume eight-word cache blocks and a set size of 256 words with set-associative mapping.
(a) Show the mapping between M2 and M1
(b) Calculate the effective memory-access time with a cache hit ratio of h = 0.95.
