A Critical Study on Cache Memory Management and Its Various Aspects: Design and Trade-offs in Cache Memory Management

Abstract

Cache memories are used in modern, medium and high-speed CPUs to holdtemporarily those portions of the contents of main memory which are {believedto be) currently in use. Since instructions and data in cache memories canusually be referenced in 10 to 25 percent of the time required to access mainmemory, cache memories permit the executing rate of the machine to besubstantially increased. In order to function effectively, cache memories mustbe carefully designed and implemented. In this paper, we explain the variousaspects of cache memories and discuss in some detail the design features and trade-offs.
