Abstract: Due to advancements of semiconductor fabrication that lead to shrinking geometries and lowered supply voltages of semiconductor devices, transient fault rates will increase significantly for future semiconductor generations [Int13]. To cope with transient faults, error detection and correction is mandatory. However, additional resources are required for their implementation. This is a serious problem in embedded systems development since embedded systems possess only a limited number of resources, like processing time, memory, and energy. To cope with this problem, a software-based flexible error handling approach is proposed in this dissertation. The goal of flexible error handling is to decide if, how, and when errors have to be corrected. By applying this approach, deadline misses will be reduced by up to 97% for the considered video decoding benchmark. Furthermore, it will be shown that the approach is able to cope with very high error rates of nearly 50 errors per second.
