FPGA Implementation of Snoopy Bus based Cache Coherence Protocols for Dual Processor System

When designing of Shared Memory Multiprocessor systems  Cache Coherence becomes the great challenge to deal because incoherence may occur when the processors are working on the same data without any coordination. This coherence can be brought by using cache coherence protocols which are finite state machines which manages the cache  and memory. This Paper aims at introducing cache coherence in details and providing a  performance analysis of some of the cache coherence protocols. Thus this work is majorly focusing on implementation of MSI, MESI and MOESI cache coherence protocols using Xilinx ISE on FPGA and the way coherence protocols are designed are analysed perfectly.
