Abstract

Le système comporte n processeurs 11, 12, 13 banalisés indépendants ayant chacun une mémoire locale de travail de capacité suffisante pour contenir les programmes de conduite du système, une mémoire commune reliée à une ligne bus sur laquelle sont branchés en parallèle les n processeurs, mémoire contenant les données du système, et des circuits d'entrée et de sortie également reliés à la ligne bus. Application aux satellites.The system comprises n independent, unmarked processors 11, 12, 13 each having a local working memory of sufficient capacity to contain the operating programs of the system, a common memory connected to a bus line to which the n processors are connected in parallel, memory containing system data, and input and output circuits also connected to the bus line. Application to satellites.
