摘要
为掌握星载计算机系统级抗辐射加固技术 ,针对星载计算机的抗辐射薄弱环节 ,研究抗辐射加固措施 ,完成了 386ex三机变结构原理样机。重点研究了抗单粒子效应多机容错技术和存储器校验技术 ,抗总剂量效应屏蔽材料和屏蔽工艺。最后研究了实时多任务操作系统及其抗辐射问题。
The thesis is aimed at to master the system level radiation hardening techniques of OBC. For the weakness of non radiation hardening OBC , we have accomplished the 386 ex prototype of flexible triple modular redundancy architecture. We focuses attention on multi-modular redundancy and error detection and correction of memory chips for SEU protection, RH materials and shielding techniques for total ionizing dose damage. Finally the real-time multitask operating system and software RH technique are studied.
