一种支持QoS片上网络路由器的设计与实现

Design and Implementation of a Router Supporting QoS for Networks-on-Chip

设计了一种8端口的NoC路由器.采用简化的VOQ结构,使用双交叉开关,可连接4个IP核,开关调度具有动态、确定和公平的特点,能够提供QoS保证,并有效降低了报文排头阻塞和片上网络面积.Synopsys Design Compiler的综合结果表明,基于0.13μm工艺实现后,面积为0.62mm2,工作频率可达500MHz.

This paper design a router with 8 ports for NoC, which uses a simplified VOQ architecture with dual crossbar, support 4 IP cores, and has dynamic arbitration which is deterministic and fair. The router can support QoS, reduce packets＇ head-of-line （HoL） blocking and area of networks-on-chip effectively. Logical synthesis was performed with the Synopsys Design Compiler using the 0. 13μm library, the results show that the standard cells area of the muter with 8 ports is 0.62mm^2, and the performance corresponds to 500MHz.
