ABSTRACT:
A multithreaded processor is programmed for executing multiple simultaneous working programs by respective processor worker threads each executing the identical code having identical results for achieving redundant operations that can be compared to each other by one or more checker threads for determining when one of the working programs or checker threads has failed for a single event fault detection and recovery of a failed worker or checker monitoring program so as to mitigate the effects of single event failure that may be due to radiation.
