本文首先介绍了系统可靠性的基本概念;详细分析了基本的可靠性保障技术,特别是软件容错和硬件容错的基本技术;归纳了制约容错技术在实时系统中的应用的两个核心问题:一是大多数容错系统以硬件容错为主,对于软件错误无能为力;二是实时计算机系统设计中软硬件耦合度低的特点不利于系统可靠性设计,特别是软件容错设计;导出了现代错误容忍设计急待解决的关键问题:确保硬件忍错,强化软件容错,在系统级整合软、硬件容错。 - This paper mainly aims at the characteristics of the hardware and software structure of the parallel computer on satellite , and has fulfilled researches of fault tolerant technique in three aspects of control theories and engineering : the first research of the system level fault - tolerant module is based on the system structure of the parallel computer on satellite , a kind of cold backup module and a kind of hot backup module for multiprocessor computer have been put forward . then the research of software fault tolerant technique which is based on the operate system named rtems has been carried , the mission level fault - tolerate arithmetic and the system level fault - tolerate mechanism and strategies based on the check point technique have been put forward , at the same time the self - repair technique of software which has used the technique of system re - inject has been studied . finally the technique of components level fault - tolerant based on fpga has been studied , a kind of two level fault - tolerant project which aims at the fault - tolerant module of the parallel computer on satellite has been put forward , and the augmentative of circuit that project design realization need is little , this project can avoid any breakdown of any part logic circuit of the fpga
本课题主要针对星载并行计算机体系结构及软件结构的特点,从如下三个方面进行了容错控制理论研究和实践工作:首先进行了基于星载多cpu并行计算机体系结构的系统级容错模型研究,提出了一种多cpu冷备份容错模型和一种多cpu热备份容错模型;然后进行了基于rtems操作系统的软件容错技术研究,提出了任务级容错调度算法以及基于检查点技术的系统级容错恢复机制和策略,同时研究了利用系统重注入进行软件在线自修复的容错技术;最后研究了基于fpga的部件级容错技术,提出了对容错模块这一星载并行计算机关键部件的两级容错方案,实现该方案所需增加的电路少,可避免板级芯片以及fpga芯片内部任何逻辑发生单点故障。
