The bus-based system has the limit on the number of processor than can be attached to the bus because of the electric and physical problems of the bus. Moreover, as the microprocessor speeds up, the bus is saturated severely - even with small number of processor. Recently, the ring-based multiprocessor system using point-to-point link is proposed to replace the bus-based multiprocessor system. In this paper, we propose an efficient snooping cache system for ring-based NUMA multiprocessor system to better the performance.
