Fault model is the basis of research on fault-tolerant routing algorithm for Network on Chip(NoC).Since the former fine-grained fault model could not distinguish link faults from channel faults effectively,a much more fine-grained fault model is put forward,and a new fault-tolerant routing algorithm named VFFrA-Br(very fine-grained fault-tolerant routing algorithm based on bufferreuse) is proposed in this paper,to improve the utilization rate of the NoC *** algorithm adopts the transparent transmission mechanism based on bufferreuse(TTBr) to tolerate internal channel faults of *** and synthesis results demonstrate that our algorithm performs better on average throughput,average latency and average hop counts of NoC while keeping a low onchip resources overhead.
