WebHigher associativity is not always feasible for two reasons: it increases cache hit latency and energy consumption. One of the main reasons for the increased latency is a … WebFor the direct-mapped cache, the average memory access latency would be (2 cycles) + (10/13) × (20 cycles) = 17.38 ≈ 18 cycles. For the LRU set associative cache, the average memory access latency would be (3 cycles) + (8/13) × (20 cycles) = 15.31 ≈ 16 cycles. The set associative cache is better in terms of average memory access latency.
