Two-Channel Router for Networks-on-Chip

提出了一种新颖的应用于片上网络的双通道路由器,该路由器使用分开的数据包通道和控制包通道,能够在相同的约束下达到更好的性能。通过对随机通信流和MPEG-4通信流的仿真,可知双通道路由器系统中两种传输包不会相互影响,且相比于传统的单通道路由器和虚通道路由器,使用双通道路由器可以达到更好的吞吐量和平均延时性能。每个路由器的电路规模仅为2.05万门,在SMIC0.13μmCMOS工艺下,综合面积仅需0.103mm2。

A novel and efficient two-channel router using separate data and control packet channels is proposed for networks-on-chip. The new scheme is compared with the traditional signal-channel and virtual-channel routers under the same traffic conditions and constraints. The simulation results show that the proposed router performs better in terms of throughput and average delay. The gate count of the router is only 20 500, and the router area after synthesis is 0.103 mm^2 under SMIC 0.13 μm CMOS process technology.
