A looped bus system includes a plurality of nodes connected by unidirectional buses having opposite directions of signal transmission. The head of bus function for one bus is located on a node different from that for the head of bus function for the other bus, the head of bus function is located on the same node as the termination of bus function for the other bus, and the head of bus function is located on the same node as the termination of bus function for one bus. As a result, the buses can be reconfigured and nodes can be added freely by the use of an unused bus portion present in a part of the looped bus under normal condition.
Cette invention concerne un réseau de bus bouclé qui comprend une pluralité de noeuds raccordés par des bus unidirectionnels transmettant des signaux en sens opposés. La fonction entrée d'un bus est raccordé à un noeud différent que celle d'un autre bus mais au même noeud que la fonction sortie de l'autre bus et la fonction entrée est raccordée au même noeud que la fonction sortie d'un bus. Par conséquent, les bus peuvent être reconfigurés et des noeuds peuvent être ajoutés sans restriction en se servant d'une partie non utilisée de bus dans le réseau bouclé, en conditions normales.
