A novel approach using a minimum cost maximum flow algorithm for fault-tolerant topology reconfiguration in NoC architectures

- An approach using a minimum cost maximum flow algorithm is proposed for fault-tolerant topology reconfiguration in a Network-on-Chip system. Topology reconfiguration is converted into a network flow problem by constructing a directed graph with capacity constraints. A cost factor is considered to differentiate between processing elements. This approach maximizes the use of spare cores to repair faulty systems, with minimal impact on area, throughput and delay. It also provides a transparent virtual topology to alleviate the burden for operating systems.
