A Review on Optimizing Cache Memory Performance

Abstract

Computers are being used as a controlling and monitoring tool in current technologies, particularly in the industrial domains, to aid in system development. As a result, slow speed and poor performance are the most common computer problems in numerous applications. The design strategy was presented in this study to demonstrate how to aid in the improvement of both speed and performance.  Many factors influence computer performance, including processor speed, RAM capacity, and the processor's cache memory strategy's weakness. These are the most significant influences on the processor's speed and performance, resulting in performance degradation. The data transport speed to/from the processor, delayed processor data access time, and processor access time are all affected by the fact that most cache memories are designed outside the processing units. To clearly demonstrate the influence of cache memory, the C++ application was used as a simulation tool for performance measurement. When the cache was created inside the processing unit, the simulation results showed that adding cache memory had a significant impact on both processor speed and computer performance. Also, when designing the cache outside of the processing unit, it yields unfavourable outcomes.  Processor performance is improving at a high rate when compared to main memory access latency. By making proper use of cache memory, the effects of this gap can be reduced. This paper's goal is to show how to improve cache performance in terms of miss rate, hit rate, latency, efficiency, and cost.
