Self-recovering controller based on TMR-token

Abstract

As the feature sizes decrease to nm,the ever increasing soft error rate continues its stronger and stronger challenge to ICs such as controllers face.A more dependable self-recovering controller structure was presented based on finite state machine splitting and token hardened.The experimental results of fault injection,simulation and synthesis on some typical benchmarks show that the presented structure achieves a perfect soft error tolerant effect at a very low cost of hardware.
