Answer:
Given cache size =128 = 2^7
Block size = 8 bytes = 2^3
Physical address = 32 bits.
It uses four-way set-associative mapping.
Therefore total no.of sets in four-way set-associative mapping = (cache size/block size*4)
= 128/32
= 4
therefore index = log2(no.of sets) = 2
offset = log2(block size) = 3
Tag = 32-2-3 => 27
