  • Achieving scaling performance as core counts increase to the hundreds in future chip-multi-processors (CMPs) requires high performing, yet energy-efficient interconnects. Silicon nanophotonics is a promising replacement for electronic on-chip interconnect due to its high bandwidth and low latency, however, prior techniques have required high static power for the laser and ring thermal tuning. We propose a novel nano-photonic NoC architecture, LumiNOC, optimized for high performance and power-efficiency. In a 64-node NoC under synthetic traffic, LumiNOC enjoys 50% lower latency at low loads and 40% higher throughput per Watt on synthetic traffic, versus other reported photonic NoCs. LumiNOC reduces latencies 40% versus an electrical 2D mesh NoCs on the PARSEC shared memory, multithreaded benchmark suite. Copyright 2012 by the Association for Computing Machinery, Inc. (ACM).
