In this paper, the authors propose a low cost method to tolerate soft errors in the main NoC router functional units, i.e., routing units, Virtual Channel (VC) allocators, and switch allocators. The idea behind their proposal is to utilize the idle routing units at neighboring input ports to do redundant Routing Computation (RC) for the local routing requests, and detect errors in the VC Allocation (VA) and Switch Allocation (SA) results by checking if they are consistent with RC results and are in legal states.
