Suppose a byte-addressable computer using set associative cache has 4Mbyes of main memory and a cache of 64 blocks, where each cache block contains 8 bytes. a) If this cache is 2-way set associative, what is the format of a memory address as seen by the cache, that is, what are the sizes of the tag, set, and offset fields? b) If this cache is 4-way set associative, what is the format of a memory address as seen by the cache? Show all work and explain how you got the answers please.
