Coarse-grain coherence tracking is a new technique that extends a conventional coherence mechanism and optimizes coherence enforcement. It monitors the coherence status of large regions of memory and uses that information to avoid unnecessary broadcasts and filter unnecessary cache tag lookups, thus improving system performance and power consumption.

Index Terms:

RegionScout, region coherence arrays, coarse-grain coherence tracking, cache tag lookups, power consumption
