Description
Summary:This paper proposes a predictive placement scheme for set-associative cache with better way-prediction hit, energy efficiency and performance. In this work, we consider the data cache subsystem, as it is one of the most power consuming micro-architectural parts of an embedded system. We propose an energy efficient way-prediction scheme with predictive placement to improve prediction hit using minimal prediction bits. We show that, this scheme has an average energy saving 67.75% as compared to conventional caching scheme. Experimental results are obtained using Simplescalar 2.0 cache simulator for SPEC95 benchmarks.
