Performance metrics for caches

Performance metrics for caches. Basic performance metric: hit ratio h h = Number of memory references that hit in the cache / total number of memory references Typically h = 0.90 to 0.97 Equivalent metric: miss rate m = 1 -h Other important metric: Average memory access time
