Memory analysis

Question. Assume we have a computer where the CPI is 1.0 when all memory accesses (including data and instruction accesses) hit in the cache. The cache is a unified (data + instruction) cache of size 256 KB, 4-?way set associative, with a block size of 64 bytes. The data accesses (loads and stores) constitute 50% of the instructions. The unified cache has a miss penalty of 25 clock cycles and a miss rate of 2%. Assume 32-?bit instruction and data addresses. Now, answer the following questions:

a) What is the tag size for the cache?

b. How much faster would the computer be if all memory accesses were cache hits?
