WebSet associative caches generally have lower miss rates than direct mapped caches of the same capacity because they have fewer conflicts. However, set associative caches are … 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.

Webprocessor is adjusted to match the cache hit latency. Part A [1 point] Explain why the larger cache has higher hit rate. The larger cache can eliminate the capacity misses. Part B [1 points] Explain why the small cache has smaller access time (hit time). The smaller cache requires lesser hardware and overheads, allowing a faster response. 2 http://csg.csail.mit.edu/6.823S20/StudyMaterials/quiz1/pset3.pdf

WebFeb 14, 2024 · Now Ben is studying the effect of set-associativity on the cache performance. Since he now knows the access time of each configuration, he wants to know the miss-rate of each one.
