A main memory has 256 k words and a cache of 4K words, both use blocks of 16 words. Show your designs for the following 3 cases: a) Set-associative memory mapping with sets holding 4 blocks. b) Direct memory mapping. c) Full associative memory mapping. For each of the above cases specify the following: Indicate how the address is divided into TAG, SET and WORD bits. Comment on the advantages and disadvantages of each. Show your work and clearly indicate your answer.
