Reconfigurable Routing Algorithm for Fault-Tolerant 2D Mesh NoCs
Presented a reconfigurable fault-tolerance routing algorithm for 2D Mesh NoCs,which can be reconfigured to adapt to the modification of the topology due to faulty routers resulting from manufacture defects and wearing out problems through lifetime,and provides the required communication for the remaining healthy nodes in spite of failures.Platform-based SystemC simulation shows its less network latency compared to traditional fault-tolerant routing algorithm.Meanwhile,deadlock-freedom and reconfigure mechanism issues are addressed.The proposed routing algorithm is highly scalable that the hardware cost of each router keeps constant independent of system size,and the fault-tolerance capability is also enhanced.
