In this paper

we proposed a new routing algorithm for 2D Mesh NoC based on the Turn Model

named Region Turn Algorithm

to achieve lower latency and higher throughput.The whole Mesh network is divided into two parts based on the current nodes X coordinate in our new algorithm.If the X coordinate of destination nodes is less than the current nodes X coordinate

we adopt the West First algorithm

whereas the North Last algorithm is implemented.The simulation results show that our algorithm can reduce the latency and improve the throughput compared with XY routing algorithm.When the load is 40 cycles/message

the latency reduce the maximum is 13.99%

throughput increased 13.56% at the load of 20 cycles/message.
