由于太空中存在各种宇宙射线辐射,导致星载设备产生可靠性问题,使得高性能数字信号处理器(DSP)在航空航天中的应用受到制约,因此需要采取容错措施来对其进行加固处理。但软加固算法会使程序复算而增加系统开销,文章基于C6748 DSP平台,详细说明了在不影响检错率的情况下的功耗优化方法。实验结果表明,通过此方法在保证检错率的条件下能显著降低系统开销,同时也提升了执行效率。
Due to the existence of various cosmic radiation in space, the reliability of on-board equipment causes the application of high-performance digital signal processor (DSP) in aerospace. Therefore, fault-tolerant measures need to be taken to reinforce it. However, the soft reinforcement algorithm will make the program re-count and increase the system overhead. Based on the C6748 DSP platform, the article details the power optimization method without affecting the error detection rate. The experimental results show that this method can significantly reduce the system overhead while ensuring the error detection rate, and also improve the execution efficiency.
