英文摘要：

Network topology and muting algorithm are key problems in Network-on-Chip design. This paper analyses existing three network topology architectures and presents a novel coding method for NoC nodes, which fits Torus topology architecture well since the node coding implies the relations of neighhouring nodes and their links. The combination of the code with Toms architecture can simplify the design and implement of muting algorithms, and improve NoC routing performance. The experiment results show that communication performance of Network-on-Chip with the coding method can be effectively improved.
