A Two Layered approach to perform Effective Page Replacement

Abstract

-In a multi processor system, when the request are performed more frequently, more effective management of cache is required. Cache is small size memory available in system that holds both data and instruction. In case of shared cache, the management of cache is more critical. Cache memory provides the static storage to the processor for most required data and instruction. As of limited size, the contents of cache are been replaced regularly. To improve the efficiency of the system, an effective cache replacement algorithm is required. The presented work is in same direction. In this work a two level cache is been defined. In first level the prioritization of the cache contents is been defined based on the type of contents. At the second level the replacement is been performed by analyzing the page utility and the frequency of the access. The analysis of the work is been performed with different cache size. The analysis of work is been performed in terms of hit ratio and miss ratio. The obtained results show that the presented work has improved the efficiency and reliability of the multiprocessor systems.
