Higher associativity to reduce miss rate
Web• Small size and lack of associativity implies higher miss rate • Compensate by reducing Miss Penalty • Structural: Multi-level caches, Critical word/Early Restart, • Latency … Web24 de fev. de 2024 · Hit ratio (H) = hit / (hit + miss) = no. of hits/total accesses Miss ratio = miss / (hit + miss) = no. of miss/total accesses = 1 - hit ratio (H) We can improve Cache performance using higher cache block size, and higher associativity, reduce miss rate, reduce miss penalty, and reduce the time to hit in the cache.

Web• Number of sectors in a set used to describe associativity – 1 sector/set is Direct Mapped = “1-way set associative” –ksectors/set is k-way set associative – All sectors in one set is fully associative • Higher associativity can improve hit rate – Reduces conflict misses – Costs more – Slower cycle time because of comparator WebReducing Conflict Miss Rates Technique 3: High associativity caches – More options for block placement → fewer conflicts – Reduce conflict miss rate – May increase hit access time because tag match takes longer – May increase miss penalty because replacement policy is more involved
