ABSTRACT:
A bus arbitration protocol and accompanying bus arbitration logic for multiple-processor computer systems in which each processing module has a local cache. Several bus arbitration policies are enforced on contending devices which effectively introduce delay states into the arbitration behavior exhibited by each device. The bus arbitration protocol employs a distributed method of arbitration control involving an essentially fixed prioritization of arbitrating devices.
