Abstract:Manycore CMP systems are expected to grow to tens or even hundreds of cores. In this paper we show that the effective co-design of both, the networkon-chip and the coherence protocol, improves performance and power meanwhile total area resources remain bounded. We propose a snoopy-aware network-onchip topology made of two mesh-of-tree topologies. Reducing the complexity of the coherence protocol -and hence its resources -, and moving this complexity to the network, leads to a global decrease in power consumpti… Show more
