Network-on-chip, routing control method, and storage medium

The invention provides a network-on-chip, a routing control method and a storage medium, and the network-on-chip comprises a plurality of routers. Each router comprises an arbitration module. And the arbitration module is connected with the lower-level router, and is configured to receive and record the transmission direction and the transmission state of each virtual channel in the routers, and determine a forwarding virtual channel in the plurality of virtual channels of the forwarding interface based on the transmission direction and the transmission state of each virtual channel. Thus, the forwarding virtual channel of the subordinate router can be determined in advance in the routing calculation of the current router on the data packet, and the forwarding virtual channel is determined based on the transmission state of the virtual channel in the subordinate router. Therefore, congestion in the process of transmitting the data packet to the lower-level router can be avoided, and the forwarding efficiency
