Abstract: In this paper, we proposed an network-on-chip model derived from traditional OSI
model and TCP/IP model. We analyzed varied topologies of NoC system, and calculated and
compared the efficiency of several switching and routing methods. In addition, the principle of
guaranteeing QoS is also discussed in this paper.
