Integrity checking based soft error recovery method for DSP

In aerospace, the single particle soft errors are more and more frequently reported in DSP and the other memory devices, which seriously impact on the system running safely and reliably. Aiming at the soft error occurred in DSP program storage areas, this paper presents an integrality-checking-based control-flow error recovery method, which can rapidly recovery a control-flow error after checking it by a little improvement of setting a recovery pointer and a recovery memory on integrality-checking-based control-flow check method. The proposed method has an important guiding significance to the design and development of DSP.
