Suppose a computer using direct mapped cache has 2^32 bytes of byte-addressable main memory and a cache size of 512 bytes, and each cache block contains 64 bytes. a. How many blocks of main memory are there? b. What is the format of a memory address as seen by cache, i.e., what are the sizes of the tag, block, and offset fields?
