摘 要: 基于硅光技术的光片上网络具有高带宽、低能耗等优点,已成为突破片上电互连网络瓶颈的有效解决方案.基于传统Mesh和Fat Tree的优势,提出了一种新的片上光互连系统结构,设计了该结构的拓扑布局、扩展方式以及路由算法等.从时延、吞吐以及能耗等方面与现有的著名网络拓扑BFT,FT和Mesh进行比较,仿真结果表明,新结构在时延吞吐性能以及成本开销等方面具有优势. Based on silicon photonic technology, optical network-on-chip (ONoC) can offer significant bandwidth and power advantages, which provides a promising solution to overcoming the limitations of traditional electronic interconnect. In this paper, based on the advantages of Mesh and Fat Tree, we propose a new ONoC including its topology, scaling and routing algorithm and so on. We have simulated and compared several ONoCs based on the topologies including Mesh, Fat Tree (FT) and Butterfly Fat Tree (BFT) in terms of the end-to-end delay, network throughput and power consumption. The results show that the new ONoC has advantages in terms of network performance and cost.
