Cache memories, while useful for improving the average-case performance for general-purpose applications, are not suitable for real-time systems due to the time unpredictability. In this paper, we propose a Performance Enhancement Guaranteed Cache (PEG-C) to ensure performance improvement in the worst case while achieving as good average-case performance as a regular hardware-controlled cache. We...
In this paper, we study how to reduce the cache leakage energy efficiently in a hybrid SPM (Scratch-Pad Memory) and cache architecture. Since SPM can reduce the access frequency to the cache, we find it is possible to place the cache lines of the hybrid SPM-cache into the low power mode more aggressively than traditional leakage management for regular caches, which can reduce more leakage energy without...
