Cache set index for associative caches
Cache set index = (BlockNumber) mod (NumberOfCacheSets)
Cache Block size = 2^N bytes Number of cache sets = 2^M
Offset = N bits
Set Index = M bits
Tag = 32 - (N+M) bits
Example
Cache set index = (BlockNumber) mod (NumberOfCacheSets)
Cache Block size = 2^N bytes Number of cache sets = 2^M
Offset = N bits
Set Index = M bits
Tag = 32 - (N+M) bits
