Given a main memory consisting of four memory modules with 256 words per module. Assume 16 words in each cache block. The cache has a total capacity of 256 words. Set-associative mapping is used to allocate cache blocks to block frames. The cache is divided into four sets.

(a) Show the address assignment for all 1024 words in a four-way interleaved organization of the main memory.

(b) How many blocks are there in the main memory? How many block frames are there in the cache?

(d) Show the mapping from the blocks in the main memory to the sets in the cache and explain how to use the tag field to locate a block frame within each set.

(e) Comment on the advantages and disadvantages of using set-associative mapping in cache organization as compared with other cache organizations
