As the size of CMOS technology scales down to nanometers domain, fault-tolerant is becoming a challenge for NoC. Turn model provides a simple and efficient systematic approach to the development of deadlock-free routing algorithms. In this paper, we propose a pseudo-receiving mechanism based on the support of local processor's cache to enable prohibited turn, and meanwhile make it keep deadlockfree. We present a fault-tolerant routing algorithm based on pseudo-receiving mechanism for 2D mesh. The routing algorithm is livelock-free in the cost of disable a few un-faulty links or nodes. The algorithm is applied to a single-cycle fixed output-buffered router. Experimental results show that, it achieves high performance even under high faulty rate.
