NoCs环形路由器微结构

A Ring Router Microarchitecture for NoCs

Wo-Tak Wu

摘要:

片上网络(NoC)已经成为片上多处理器设计中连接大量处理核的流行选择。在传统的NoC设计中,路由器中的大部分区域被缓冲器和交叉开关占据。这两个组件也消耗了路由器的大部分功率。NoC的许多研究都是基于传统的路由器微体系结构。我们提出了一种新的路由器微架构,把路由器本身作为一个小型网络的环形拓扑结构。它消除了传统设计中的大型交叉开关。此外,网络延迟也大大减少。仿真和电路综合表明,所提出的微架构可以减少延迟53%,面积和功耗分别为34%和27%,与传统的设计相比。

英文摘要:

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.
