A Cache Memory System based on a Dynamic/Adaptive Replacement Approach

In this work we propose a cache memory system based on an adaptive cache replacement scheme, as part of the virtual memory system of an operating system. We use a sequential discrete-event simulator of a distributed system to compare our approach with previous work. Our adaptive cache replacement scheme is based on several criteria about the system and applications with the objective being to estimate/choose the best replacement policy. We assign a replacement priority value to each cache block according to a set of criteria to select which block to remove. The goal is to provide an effective utilization of the cache memory and good application performance.
