Memory Hierarchy Q.39

39The main memory of a computer has 2 cm blocks while the cache has 2 c blocks. If the cache uses the set associative mapping scheme with 2 blocks per set, then block k of the main memory maps to the set

Option : B
Explanation : Since the cache has 2c blocks and there are 2 blocks per set, the cache thus has c sets. So, block k of the main memory would map to block (k mod c) of the cache.
