Abstract :
A novel software-implemented hardware fault tolerance method based on encoding both the control and the data-flow segments of programs with matrices is proposed and evaluated. Results show an average speed-up of 3 times compared to standard duplication and comparison, with coverage higher than 95% for the case studies considered, which outperforms previous works in the field.
