A strategy to handle multiple defects in the No Clinks with almost no impact on the communication delay is presented. The fault-tolerant method can guarantee the functionally of the NoC with multiple defects in any link, and with multiple faulty links. The proposed technique uses information from test phase to map the application and to configure fault-tolerant features along the NoC links. Results from an application remapped in the NoC show that the communication delay is almost unaffected, with minimal impact and overhead when compared to a fault-free system. We also show that our proposal has a variable impact in performance while traditional fault-tolerant solution like Hamming Code has a constant impact. Besides our proposal can save among 15% to100% the energy when compared Hamming Code.
