Design of NoC Router Based on High Speed Data Acquisition

Since the quantity of data process for NoC is more and more large, the packet transmission delay is increased with the deterministic algorithm. However, the simple adaptive algorithm takes too many on-chip resources.To solve the problems, the improved XY adaptive routing algorithm is adopted in this paper. We design node based on 2D_Mesh topology structure and wormhole switching mode of virtual channel technology. In addition, VerilogHdl language is used to complete the design of each part function for NoC routing node. Finally, the simulation experiment is carried out on Modelsim software and the function of NoC routing node is implemented on FPGA. Experimental results show that, the router designed in this paper can satisfy the process of high speed data and avoid the delay and deadlock issues.
