星载大规模数字处理系统单粒子效应防护技术研究

摘要

空间辐射环境会给大规模数字处理系统引入单粒子翻转效应问题，严重影响系统运行的可靠性。文章从星载大规模数字处理系统的发展需求出发，对解决单粒子翻转效应问题的软防护技术和宇航ASIC技术路线发展现状和方向进行研究和分析，最终提出两条技术路线的发展建议。%The single event upset ( SEU ) from the space environment threatens to the reliability of space-borne large-scale digital processing systems .Based on the development requirement of such system ,the paper focuses on the state of art of the anti-radiation technology and aerospace ASIC technology ,which are employed to mitigate the SEU effects .Then sug-gestions on two development routes are promoted in this article .
