论文摘要
网络芯片（NOC）已成为连接芯片多处理器设计中大量处理核心的流行选择。在常规的NOC设计中，路由器中的大多数区域都被缓冲区和横梁开关所占据。这两个组件还消耗了路由器的大部分力量。 NOC的大部分研究都是基于常规路由器微体系结构。我们提出了一个新型的路由器微体系结构，将路由器本身视为环形拓扑的小网络。它消除了传统设计中的大型横梁开关。此外，网络延迟大大减少了。模拟和电路合成表明，与常规设计相比，所提出的微观结构可以将潜伏期，面积和功率分别降低53％，34％和27％。
Network-on-Chip (NoC) has become a popular choice for connecting a large number of processing cores in chip multiprocessor design. In a conventional NoC design, most of the area in the router is occupied by the buffers and the crossbar switch. These two components also consume the majority of the router's power. Much of the research in NoC has been based on the conventional router microarchitecture. We propose a novel router microarchitecture that treats the router itself as a small network of the ring topology. It eliminates the large crossbar switch in the conventional design. In addition, network latency is much reduced. Simulation and circuit synthesis show that the proposed microarchitecture can reduce the latency, area and power by 53%, 34% and 27%, respectively, compared to the conventional design.
