Abstract
A cache-coherent, multiple-bus, multiprocessing system and method interconnects multiple system buses and an I/O bus to a shared main memory and efficiently maintains cache coherency while minimizing the impact to latency and total bandwidth within the system. The system provides coherency filters which coordinate bus-to-bus communications in such a way as to maintain cache memory coherency with a small amount of cross-bus traffic. In addition, the system provides a multiported pool of memory cells which interconnect the multiple buses.
