A byte-addressable main memory of size 256MB with blocks of 32 bytes in size. The cache memory can hold up to 512blocks of data in addition to the space for tag and validity bit. Show the fields in a memory address (the name of each part and its length in bits) and the actual size of cache memory in bits (i.e. the storage for data plus tags and validity bits) for each of the following organizations. a. Full Associative b. Direct-mapping C. 2-way set associative For each of the three above cache memory organizations, compute the offset, index or set, and tag for the address 224 +20 +7.
