Abstract: In order to solve the problems of too many hops in the routing node of the existing network topology, the longer network diameter and the imbalance load, a new MECS Topology Network, which broadcasts in the XY direction, is used. So the data from source address to the target address are only through a maximum of two router nodes. We adopt the form of input buffer with a virtual channel based on the original and the output buffer under the crossbar scheduling control so they can execute in a parallel way, while the business can prioritize the transmission of real-time communication and reduce power consumption. The Modelsim simulation shows that the Routing Node can achieve a shorter average delay, increase throughput, improve the network performance and quality of service.
