Fault-tolerant Routing Algorithm of NoC
QV Lingxian · Electronics & Packaging · 2015
Various software and hardware faults can destroy data transmission on the network, so it is essential to study fault-tolerant methods of Network-on-Chip(No C). In the paper, a modified fault-tolerant routing algorithm is proposed based on the XY algorithm, which can achieve an efficient route way by resetting the route rule when error occurred on the path of chain or between the nodes. The simulation results of the fault-tolerant routing algorithm based on FPGA are compared with the current commonly used routing algorithms on the applicable topology, whether to prevent deadlocks and so on; the simulation results show that the performance and feasibility of proposed modified fault-tolerant routing algorithm are both well.
