Abstract
Abstract: In this new age of technology, not only the software but also the computer architecture has beenevoluted to support those softwares. The main motive of evolution of architecture day by day is to make thesystem faster. One of the major steps in this journey of evolution is the multi-core processor architecture. In amulti-core processor system, each core has its own cache module where they are sharing the same memory unit.For that reason, one block in one cache gets invalidate when the same block is updated into any other cacheand this is called cache coherence problem. To overcome this, there are lot of research works are going on andthe outcome rules or techniques are called cache coherence protocols.The main objective of this paper is tocollect all those research works together and represent them in an easy way, so that we could understand theirtechniques to overcome the particular problem. Here it is presented a comprehensive study of those cachecoherence protocols with their pros and cons.
