Abstract
Circuit de raccordement d'interface d'entrée/sortie dans un système de traitement de données destiné à renforcer les signaux transmis sur l'extension du bus d'entrée/sortie. L'interconnexion des lignes d'adressage et de données du bus d'entrée/sortie et de l'extension est réalisée par les circuits de commande bidirectionnels 170 et 171 alors que l'interconnexion des lignes de commande est réalisée par les circuits de commande est réalisée par les circuits de commande unidirectionnels 174 et 175. Une unité logique 178 permet de commander le sens de transmission des signaux d'adressage ou de données sur les bus d'entrée/sortie. Application aux interfaces entre les systèmes de traitement de données et les dispositifs périphériques raccordés.
