片上通信被广泛认为是当代芯片多处理器(CMPS)的主要性能瓶颈之一。随着硅纳米光子学的最新进展，基于光子学的片上网络(NoC)体系结构被认为是支持未来CMP通信的可行解决方案，因为它们可以实现比传统电学NoC更高的带宽和更低的功耗。在本文中，我们提出了SwiftNoC，这是一种新型的可重新配置的硅-光子NoC体系结构，其特点是改进了支持多播的通道共享，并在运行多个应用的核心集群之间动态重新排序和交换带宽，以提高通道利用率和系统性能。实验结果表明，与最先进的解决方案相比，SwiftNoC将吞吐量提高了25.4倍，延迟降低了72.4%，每位能耗降低了95%。
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.
