摘　　要：空间环境中,DSP等器件越来越频繁地发生单粒子软错误,严重影响了系统安全可靠地运行。针对DSP程序存储区的软错误,本文提出了一种基于完整性检查的控制流错误恢复方法。该方法在基于完整性检查的控制流错误检测方法的基础上,只需设置一个恢复指针和恢复存储区,即可在检测到控制流错误之后快速地恢复控制流错误。论文提出的方法对DSP的抗软错误加固设计与开发具有重要的指导意义。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-check- ing-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 the integrality-checking-based control-flow check method. The proposed method has an important guiding significance to the design and development of DSP.
