Design of a Router for Network on Chip Based on System Level Based on Adaptive Routing Algorithm

For disadvantages of the router which adopts determined routing algorithm, a system-level model of NoC router is proposed. This router adopts adaptive routing algorithm instead of XY ordered routing algorithm which is widely used in 2D Mesh topology. The router chooses the output ports for data transmitting by the states of current output ports and GS packets have higher priority. The router is modeled on the SystemC platform. Verification results show that the designed of router improve the parallel transmitting ability and support guaranteed service.
