Adaptive approach to tolerate multiple faulty links in Network-on-Chip

A novel approach to handle multiple defects in the NoC links 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 to know where and when fault-tolerant features must be turned on. Comparisons with popular solutions based on EDAC show that the proposed method can provide a faster communication, while coping with multiple defects in the link without the need of extra wires. In addition, the adaptive approach saves energy because it is used only when required.
