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(duì)星載并行計(jì)算機(jī)體系結(jié)構(gòu)及軟件結(jié)構(gòu)的特點(diǎn),從如下三個(gè)方面進(jìn)行了容錯(cuò)控制理論研究和實(shí)踐工作:首先進(jìn)行了基于星載多cpu并行計(jì)算機(jī)體系結(jié)構(gòu)的系統(tǒng)級(jí)容錯(cuò)模型研究,提出了一種多cpu冷備份容錯(cuò)模型和一種多cpu熱備份容錯(cuò)模型;然后進(jìn)行了基于rtems操作系統(tǒng)的軟件容錯(cuò)技術(shù)研究,提出了任務(wù)級(jí)容錯(cuò)調(diào)度算法以及基于檢查點(diǎn)技術(shù)的系統(tǒng)級(jí)容錯(cuò)恢復(fù)機(jī)制和策略,同時(shí)研究了利用系統(tǒng)重注入進(jìn)行軟件在線自修復(fù)的容錯(cuò)技術(shù);最后研究了基于fpga的部件級(jí)容錯(cuò)技術(shù),提出了對(duì)容錯(cuò)模塊這一星載并行計(jì)算機(jī)關(guān)鍵部件的兩級(jí)容錯(cuò)方案,實(shí)現(xiàn)該方案所需增加的電路少,可避免板級(jí)芯片以及fpga芯片內(nèi)部任何邏輯發(fā)生單點(diǎn)故障。
