Simple fault‐tolerant method to balance load in network‐on‐chip
Ruilian Xie, Jueping Cai, Xin Xin · Electronics Letters · 2016
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.
