Average Memory Access Time Reduction Via Adding Victim Cache

摘要

Memory hierarchy performance, specifically cache memory performance, is an increasingly important factor in evaluating the performance of modern computers. Victim caching is an improvement to miss caching by placing a small fully-associative cache between a cache and its refill path [1]. This paper presents simulation results of two-level cache memory using victim caching, and examines the impact of using the victim cache in improving system performance. Many experiments were conducted and results were recorded, and the performance was illustrated using the percentage of reduction of the average memory access time (AMAT) metric. Experiments indicated that significant performance advantages can be gained through the use of victim caching.
