Key Concepts

Hit Rate Formula Hit Rate = Hits ÷ (Hits + Misses) × 100%

AMAT AMAT = Hit Time + (Miss Rate × Miss Penalty)

Temporal Locality Recently accessed data is likely to be needed again — this is why caching works.

Direct Mapping Index = Address mod Cache_Lines. Each memory block maps to exactly one cache line.
