It is necessary to suppress the average delay to low when a packet is forwarded from a source node to a destination node in network-on-chip (NoC) for the quality maintenance of the communication between nodes. Routing algorithms have a prominent impact on communication quality and performance in on chip interconnection networks. In this paper, we present a novel routing method called Predominant Routing which can select the best route for communication flows using a simple setup network. In the setup network time, a number of low-latency virtual point-to-point connections are provided to construct the best route at run time when a new flow (a connection between a source and its destination to carry messages) is detected. Evaluation results show that the proposed routing algorithm consumes low power and approach to extremely low latency in packet switched networks-on-chip.
