- Abstract
Caching is a key method used to close the latency gap between memory and the CPU by using locality in memory accesses. varied cache replacement algorithms have radically varied effects on system performance because they choose which blocks to evict from cache memory in the event of a cache miss. The goal of these replacement strategies is to move closer to the ideal scenario by making the greatest use of the entire cache area, reducing the miss ratio as much as feasible, and obtaining the maximum system performance possible. In this paper, based on clock with adaptive replacement algorithm (CAR), a simple and effective modified algorithm is proposed, namely, modified clock with adaptive replacement (M-CAR), which achieved 91% and 76% hit ratio higher (compared with the conventional CAR method) with datasets that contained 245 and 270 items, respectively. Which is considered to be the most important cache performance criteria. Which means, by default, minimizing the cache miss ratio. As well as the dynamical behavior that has been improved and gained the (M-CAR) that makes it more reliable.
