OTORNoC: Optical tree of rings network on chip for 1000 core systems

摘要

Optical Networks on Chip are an emerging communication platform for high performance multi core systems on chip. In this work a novel thousand core topology is proposed that increases optical link utilization and scales up bandwidth to enable single chip TeraFlops performance. Performance benefits of about 1.8× and 3× reduction in optical power is obtained over the existing state of the art multicore chips.
