9)

Assume there is a direct

-

mapped cache with eight entries. The following is a sequence of eight memory references to an empty cache:

26, 18, 26, 22, 6, 22, 26, 22 .

Show each of the reference whether it causes a miss or a hit. Show also which of the misses are compulsory and which of them are conflict misses.

10)

If we configure the cache in Question

9

as a two

-

way set

-

associative cache, how many sets will there be and show whether each of the memory reference given in Question

9

causes a miss or a hit assuming the cache uses the least recently used policy for removal. Show also which of the misses are compulsory and which of them are conflict misses.
