摘　　要：针对片上网络路由器功耗问题,在系统级层次上对影响路由器功耗的虚通道数目、缓存深度和数据微片位数等关键因素进行了研究。提出了综合多种功耗关键因素以及虚拟通道共享交叉开关输入端口的功耗降低方法,设计实现了一种低能耗的NoC路由器。实验结果表明,与Alpha 21364路由器和IBM Infini Band路由器相比,所设计的路由器具有较低的功耗。Concerning the power consumption of routers based on Network on Chip（NoC）,the key factors that influence the router power consumption were studied on the systematic level,such as the number of virtual channels,the depth of buffer and the width of flit.A method of reducing power consumption was presented by incorporating various key factors of power consumption and making the virtual channels share the switch input port.And then a NoC-based router with low-power consumption was implemented.The experimental results show that the designed router has lower power consumption in comparison with the Alpha 21364 router and the IBM InfiniBand router.
