A Fault Detection Mechanism in a Data-flow Scheduled Multithreaded Processor. Fu, J., Yang, Q., Poss, R., Jesshope, C., & Zhang, C. In Proc. 2014 Conference on Design, Automation and Test in Europe (DATE'14), pages 1–4, Dresden, Germany, March, 2014. IEEE.

This paper designs and implements the Redundant Multi-Threading (RMT) in a Data-flow scheduled Multi-Threaded (DMT) multicore processor, called Data-flow scheduled Redundant Multi-Threading (DRMT). Meanwhile, It presents Asynchronous Output Comparison (AOC) for RMT techniques to avoid fault detection related inter-core communication and alleviate the performance and hardware overheads induced by output comparison. Results show that the performance overhead of DRMT is less than 60% even when the number of threads is four times the number of processing elements. Also the performance and hardware overheads of AOC are insignificant.
