Suppose a computer using 4-way associative cache has 128Mbytes (i.e. 227 bytes) of byte-addressable main memory and a cache of 128 blocks, where each cache block contains 64 bytes.

a. How many blocks of main memory are there? Please note the size block in main memory is same with the size of block in cache.

b. What is the format of a memory address as seen by the cache, that is, what are the size of the tag, set and word fields?
