SWIFTNoC
Abstract
On-chip communication is widely considered to be one of the major performance bottlenecks in contemporary chip multiprocessors (CMPs). With recent advances in silicon nanophotonics, photonics-based network-on-chip (NoC) architectures are being considered as a viable solution to support communication in future CMPs as they can enable higher bandwidth and lower power dissipation compared to traditional electrical NoCs. In this article, we present SwiftNoC , a novel reconfigurable silicon-photonic NoC architecture that features improved multicast-enabled channel sharing, as well as dynamic re-prioritization and exchange of bandwidth between clusters of cores running multiple applications, to increase channel utilization and system performance. Experimental results show that SwiftNoC improves throughput by up to 25.4× while reducing latency by up to 72.4% and energy-per-bit by up to 95% over state-of-the-art solutions.
