In shared bus-based multiprocessor system-on-a-chips (MPSoCs), snoop-based schemes are widely used to maintain cache coherency. However, many of broadcasts are useless because remote caches seldom have the matching blocks and their tag lookups do not supply data. From the energy perspective, such tag lookups consume unnecessary energy and make the system(More)
Broadcast filtering technique is useful in reducing the snoopenergy consumption of shared bus-based MPSoCs by intelligently avoiding useless coherency-request broadcasts. Since the patterns of coherency-request broadcasts are highly dependent on how concurrent tasks are assigned to multiple processors, a broadcast filtering-aware task assignment is(More)
