Worst-case performance guaranteed data cache

Abstract

In this paper, we propose a Performance Enhancement Guaranteed Cache (PEG-C) to ensure performance benefit in the worst case while achieving as good average-case performance as a regular hardware-controlled cache. Our experiments indicate that with a small number of preloaded data and a simple hardware extension, the PEG-C can guarantee performance enhancement in the worst case while achieving the same average-case performance as a regular cache.
