Abstract: A Network-on-Chip(NoC) routing algorithm is proposed to improve the routing efficiency, it is an adaptive and minimal-path algorithm. By employing multi-priority before data transfer, it increases system’s throughput and reduces the network latency. The algorithm is simulated on a 4×4 2D mesh network using the NIRGAM simulation platform. By comparing with the other algorithms, it shows that the algorithm has a better performance in hotspot traffic pattern.
