ABSTRACT:
The present invention provides for a bus system having a local bus ring coupled to a remote bus ring. A processing unit is coupled to the local bus node and is employable to request data. A cache is coupled to the processing unit through a command bus. A cache investigator, coupled to the cache, is employable to determine whether the cache contains the requested data. The cache investigator is further employable to generate and broadcast cache utilization parameters, which contain information as to the degree of accessing the cache by other caches, its own associated processing unit, and so on. In one aspect, the cache is a local cache. In another aspect, the cache is a remote cache.
