Evaluating associativity in cpu caches

WebConflict misses can be a problem for caches with low associativity (especially direct-mapped). 2:1 cache rule of thumb: a direct-mapped cache of size N has the same miss rate as a 2-way set-associative cache of size N/2. However, there is a limit -- higher associativity means more hardware and usually longer cycle times (increased hit time). WebThis paper presents (1) new and efficient algorithms for simulating alternative direct-mapped and set-associative caches, and (2) uses those algorithms to quantify the effect of …

Cache is graded as Level 1 (L1), Level 2 (L2) and Level 3 (L3): L1 is usually part of the CPU chip itself and is both the smallest and the fastest to access.
