STUDY OF MEMORY ORGANIZATION AND MULTIPROCESSOR SYSTEM -USING THE CONCEPT OF DISTRIBUTED SHARED MEMORY, MEMORY CONSISTENCY MODEL AND SOFTWARE BASED DSM.

Abstract

In current trend, performance and efficiency is the big issue of the memory organization and multiprocessor system whereas, A Memory Organization and Multiprocessor uses multiple modalities to capture different types of DSM (Software based, Hardware Based and it may be combine both Software & Hardware etc) because IT technology is greatly advanced and lot's of information is shared via the internet. To improve the performance and efficiency of that multiprocessor system and memory organization, we can use different type of techniques that is based on the concept and implementation of Hardware, Software, and Hybrid DSM. This paper provides an almost exhaustive survey of the existing problem and solutions in a uniform manner, presenting their memory organization, shared memory, distributed memory, distributed shared memory, Memory Consistency Model and software based DSM mechanisms and issues of importance for various DSM systems and approaches.
