ABSTRACT:
A point-to-point connected multiprocessing node uses a snooping-based cache-coherence filter to selectively direct relays of data request broadcasts. The filter includes shadow cache lines that are maintained to hold copies of the local cache lines of integrated circuits connected to the filter. The shadow cache lines are provided with additional entries so that if newly referenced data is added to a particular local cache line by “silently” removing an entry in the local cache line, the newly referenced data may be added to the shadow cache line without forcing the “blind” removal of an entry in the shadow cache line.
