An adaptive cache replacement policy based on fine-grain reusability monitor

Abstract

This paper proposes an adaptive cache replacement policy to select a victim block based on the reuse characteristics of stored blocks by utilizing the fine-grain reusability monitor for each cache set. The evaluation result shows that the proposed mechanism can achieve a performance improvement of about 13% on average over conventional 2 MB cache and can deliver performance comparable to four times bigger cache, i.e., an 8 MB last level cache (LLC).
