Title
Partial Tag Comparison: A New Technology for Power-Efficient Set-Associative Cache Designs
Abstract
We call comparing a small part of two tags a Partial Comparison.In this paper, we show that the partial comparisonmethod can filter out most of the unmatched tag comparisonsfor different cache configurations. The delay of thepartial comparison operation is only 60% of that of the fullcomparison. This paper proposes to use the partial comparisontechnique to reduce energy dissipation on major cachecomponents of set-asscociative caches. We show that whenadaptive schemes based on partial comparison are appliedto amplifiers and bit-lines, the power consumption of set-associativecaches is similar to that of direct-mapped caches.We used the CACTI cache model to evaluate the proposedcache architecture and the Simplescalar CPU simulatorto produce final results. The power simulation resultssuggest that the proposed set-associative cache architectureis very power-efficient. In the simulated cache configurations,25%-60% of cache accessing engergy was saved.
