Bank Conflicts in Cache Tags

Karp, Alan H.; Hantler, Sidney



Abstract: We would like to know the sustained performance of a cache system with inter-leaved, multi-ported cache tags when it is presented with more address references than it has ports to handle. This report describes a program used to count the number of bank conflicts in the cache tags and an analysis of a formula for computing the probabilities directly.
