Abstract
L'INVENTION CONCERNE UN SYSTEME DE TRAITEMENT DE DONNEES ET NOTAMMENT UN SYSTEME COMPRENANT PLUSIEURS BUS COMMUNS A PLUSIEURS UNITES DE TRAITEMENT DE DONNEES. L'UNITE CENTRALE CPU 200 ALLOUE CES BUS A L'UNE DES UNITES, EN REPONSE A L'UNE DES DEMANDES RECUES DES UNITES DESIRANT UTILISER LES BUS COMMUNS. LES DEMANDES DE BUS SONT GENEREES DE MANIERE SYNCHRONE PAR L'UTILISATION D'UN SIGNAL DE SYNCHRONISATION PROVENANT DE L'UNITE CENTRALE 200, QUI EST CONNECTEE EN SERIE ENTRE UNE OU PLUSIEURS UNITES SUR CHACUN DES BUS COMMUNS. APPLICATION AUX TRANSFERTS D'INFORMATION ENTRE UNE UNITE CENTRALE DES MEMOIRES ET DES APPAREILS PERIPHERIQUES.
