摘要:Fully associative caches enable all blocks to map address. This paper proposes an algorithm to enable one fully associative block. The address a is right shifted by certain prefixed number of bits. The result is XOR�ed with n-1, n being the number of fully associative cache blocks. The bit selection of the result to map to one of the n blocks in fully associative cache is performed. The chosen block is enabled to access a line or place cache line. The proposed algorithm is simulated with SPEC2K benchmarks. The average memory access time is improved by 16% with energy savings of 9%. The proposed model shows 30% degradation in average memory access time with no change in energy consumption over direct mapped cache of same size.
