Separated caches and buses for multiprocessor system

The proposed scheme exploits the concept of shared cache and private cache technique. The caches are separated as shared block caches and private block caches instead of using only private caches or shared cache in the multiprocessor system. Shared block caches are working in semi-critical section (a data item can be read by two or more processors but can be written only by one processor at a time). Both shared and private block caches have their own buses. The simulation results obtained are compared with the pure private cache schemes.>
