包连接电路路由器是一种典型的电路交换路由器，但是仿真实验表明，包连接电路路由器的链路利用率很低，通讯性能较差。特别对于核间同步与命令传输的短报文，包连接电路路由器的通讯性能极差，严重限制系统整体性能提升。针对该问题，文章提出了支持虚拟电路机制的包连接电路路由器。实验结果表明，相比于包连接电路路由器，新路由器使得平均切片延迟降低约26.3％，饱和注入率提高约25.0％。

Packet connected circuit (PCC) router is classified as circuit switching router .The experi‐mental results show that the link utilization rate of PCC router is very low ,so PCC router has poor communication performance ,especially for short packet transmission ,w hich damages the w hole per‐formance of the system .To solve this problem ,the packet connected circuit router with virtual‐circuit mechanism (VCPCC) is proposed .It is proved that compared with PCC router ,the new router reduces the average flit latency by 26.3% and improves the saturation injection rate by 25.0% .
