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 本課題主要針對星載并行計算機體系結構及軟件結構的特點,從如下三個方面進行了容錯控制理論研究和實踐工作:首先進行了基于星載多cpu并行計算機體系結構的系統級容錯模型研究,提出了一種多cpu冷備份容錯模型和一種多cpu熱備份容錯模型;然后進行了基于rtems操作系統的軟件容錯技術研究,提出了任務級容錯調度算法以及基于檢查點技術的系統級容錯恢復機制和策略,同時研究了利用系統重注入進行軟件在線自修復的容錯技術;最后研究了基于fpga的部件級容錯技術,提出了對容錯模塊這一星載并行計算機關鍵部件的兩級容錯方案,實現該方案所需增加的電路少,可避免板級芯片以及fpga芯片內部任何邏輯發生單點故障。
