Question

Consider the following reference

String given as WORD addresses:

1, 4, 8, 5, 20, 17, 19, 56, 9, 11, 4, 43, 5, 6, 9, 17.

Using the same reference string above, indicate the Hits and Misses and show the state

of the cache after each address including the final contents for a Set Associative cache

with a total size of 16 words, a Block frame size of one-word and a Set size of 2 (that is,

2 block frames per set). Within a Set, assume a FIFO (First In First Out) policy for block

replacement. Assume the cache is initially empty.
