Simple fault-tolerant method to balance load in network-on-chip

A fault-tolerant odd–even (FTOE) turn model and load-balancing multi-router fault-tolerant (LBMF) routing method that do not use virtual channels for mesh network-on-chip (NoC) are presented. Applying FTOE rules and routing packets around faulty regions in advance, LBMF balances the load around the...

Zusammenfassung:A fault-tolerant odd–even (FTOE) turn model and load-balancing multi-router fault-tolerant (LBMF) routing method that do not use virtual channels for mesh network-on-chip (NoC) are presented. Applying FTOE rules and routing packets around faulty regions in advance, LBMF balances the load around the faulty regions, and then the fault-tolerant paths are shortened. Simulation results show that LBMF's network injection rate can be improved than related works by 25, 40% for 16 × 16 mesh and in the presence of 20 faults.
