| Abstract: | In this paper, the developments of space microprocessor in recent years are discussed, The content is divided into 3 sections: (a) the typical applications of space.microprocessors in Europe, India and Japan. Particularly the use of redundent and fault-tolerant techniques to increase the reliability and effective operating period is pointed out, (b) the single event upset (SEU) which is the main cause of instantaneous errors in microprossors can be overcome in several ways, and fault-tolerant technique is one of effective ways,(c)perspect and trend of development in recent years. |
