A flexible insertion policy for dynamic cache resizing mechanisms

Abstract

This paper proposes a novel cache replacement policy named a flexible insertion policy (FLEXII) for dynamic cache resizing mechanisms. FLEXII can reduce the number of dead-on-fill blocks, which are never reused in a cache memory, and help the mechanisms further reduce the energy consumption. The experimental results indicate that FLEXII can reduce the energy consumption of the cache memory by up to 68%, and 27% on average without significant performance degradation.
