Abstract
L'invention concerne un dispositif de transmission de données lequel comporte un dispositif d'échange de messages entre des unités fonctionnelles, comprenant une ou plusieurs lignes communes de transmission bilatérales de données. Chaque unité fonctionnelle est reliée à la ligne commune par un coupleur dans lequel l'adresse de destination d'un message est décodée pour sélectionner directement le coupleur de destination, sans perte de temps. L'invention s'applique des dispositifs de traitement de données comportant plusieurs unités fonctionnelles.The invention relates to a data transmission device comprising a device for exchanging messages between functional units, comprising one or more common bilateral data transmission lines. Each functional unit is connected to the common line by a coupler in which the destination address of a message is decoded to directly select the destination coupler, without loss of time. The invention applies to data processing devices comprising several functional units.
