A snoop cache protocol is proposed for the WSI implementation which minimizes the access to the shared memory. In modified-Keio protocol, both write-invalidate and write-update type protocols can be used according to the nature of the shared data. It also supports the simple synchronization mechanism with Fetch&Dec operation and inter-processor interrupt. Detailed simulation with practical parallel applications demonstrates the efficiency of this proposed protocol.
