Networks on Chips (NoCs) provide a mechanism for handling complex communications in the next generation of integrated circuits. At the same time, lower yield in nano-technology, makes self repair communication channels a necessity in design of digital systems. This paper proposes a reliable NoC architecture based on specific application mapped onto an NoC. This architecture is capable of recovering from permanent switch failures via replacing them by neighboring switches. This method has hardware and power consumption overhead, but significantly improves reliability and has a very little effect on the performance of the system. We suggest a reliability analysis method based on the combinatorial reliability models and use it to evaluate our proposed fault-tolerant NoC architecture.
