Abstract

Data or instructions that are regularly used are saved in cache so that it is very easy to retrieve for the purpose of increase the cache performance. Evaluating the execution of multi-core systems the part of the cache memory is very important. A multicore processor is shared circuit in which two or more processors are joined to enhance the performance and perform multiple tasks. This paper describes the performance of cache memory based on cache access time, miss rate and miss penalty. Cache mapping methods are defined to increase the performance of cache but it face many difficulties. Some methods and algorithms are used to decrease these difficulties. In this paper describes the study of recent competing processors to evaluate the cache memory performance.
