Abstract:

A new fault-tolerant mechanism is presented in order to ensure the reliability of NoC(network-on-chip). Thus the reliability of NoC reduces than before. The proposal is capable of recovering from permanent router faults via replacing them by neighboring routers. Configure a status register for each router in order to store the safety of neighboring routers. Adopt a new reconfigurable fault-tolerant routing algorithm to bypass the fault routers so as to improve the reliability of NoC. Simulation results demonstrate the advantage of our routing algorithm in terms of latency compared to other fault tolerant routing algorithms.

Key words: network on chip, key IP core, communication recovery, fault-tolerant routing algorithm
