A Survey of Approaches used in Parallel Architectures and Multi-core Processors, For Performance Improvement

Abstract

Multi-core architecture is the necessity of today's world. Now Moore's law has gone, speed of processors can not be increase because, we have reached in the limit of physics law. Further increase of speed of single processor is not possible. Energy requirement is the biggest hurdle of the multi-core architecture. There is a need to find out basics of multi-core processors, which will help in increasing the speed of multi-core processor and finding the problems of multi-core processors. We must have to also understand that multi-core concept has came after the parallel processors concepts. There is a possibility, that all the concepts that are used in parallel processors may be used in the multi-core processors. In this paper we will try to find out what are the concepts/techniques which can be used in the multi-core processors, and what are those concepts which can be used as it is in the multi-core processors. After the detailed study, there is a scope of finding the new techniques that can be used in multi-core architecture. In this paper we will compare major techniques, concepts that are different in parallel processors like multi-processors. © Springer International Publishing Switzerland 2015.
