In future microprocessors, communication will emerge as the major bottleneck. The authors advocate composing future interconnects of some wires that minimize latency, some that maximize bandwidth, and some that minimize power. A microarchitecture aware of these wire characteristics can steer on-chip data transfers to the most appropriate wires, thus improving performance and saving energy.
