Abstract
A.SYSTEME DE TRAITEMENT DE DONNEES NUMERIQUES COMPRENANT UNE INTERCONNEXION DES DIVERS ELEMENTS QUI CONSTITUENT LE SYSTEME. B.CHAQUE ELEMENT RELIE A L'INTERCONNEXION S'APPELLE UN "NEXUS". POUR QU'UN ELEMENT PUISSE COMMUNIQUER AVEC UN AUTRE ELEMENT, LE PREMIER ELEMENT, EN TANT QUE NEXUS DE COMMANDE, CHERCHE A OBTENIR LE CONTROLE DE L'INTERCONNEXION ET TRANSMET ENSUITE UNE COMMANDE ET UNE ADRESSE D'UNE POSITION DE MEMOIRE A L'AUTRE ELEMENT LORSQU'IL RECOIT LE CONTROLE DE L'INTERCONNEXION. LE CONTROLE EST ENSUITE ABANDONNE A MOINS QUE LE PREMIER ELEMENT DOIVE ENVOYER DES DONNEES A L'AUTRE ELEMENT, DANS QUEL CAS LES DONNEES SONT ENVOYEES IMMEDIATEMENT. SI LES DONNEES DOIVENT ETRE RECUPEREES, L'AUTRE ELEMENT RECUPERE LES DONNEES, DEMANDE LE CONTROLE DE L'INTERCONNEXION ET, LORSQU'IL L'OBTIENT, TRANSMET LES DONNEES SUR L'INTERCONNEXION AVEC UNE IDENTIFICATION DU PREMIER ELEMENT. CELUI-CI RECUPERE ENSUITE LES DONNEES DE L'INTERCONNEXION LORSQU'IL RECONNAIT SA PROPRE IDENTIFICATION. SI L'AUTRE ELEMENT EST UN ELEMENT DE MEMOIRE, IL CONTIENT EN OUTRE UN FICHIER DE STOCKAGE POUR LE STOCKAGE DE COMMANDES ET DE DONNEES S'IL EST DEJA EN TRAIN DE REPONDRE A LA COMMANDE D'UN AUTRE ELEMENT. C.APPLICATIONS DANS LE DOMAINE DE L'INFORMATIQUE.A.DIGITAL DATA PROCESSING SYSTEM INCLUDING INTERCONNECTION OF THE VARIOUS ELEMENTS WHICH MAKE UP THE SYSTEM. B. EACH ELEMENT CONNECTED TO THE INTERCONNECTION IS CALLED A "NEXUS". FOR AN ELEMENT TO COMMUNICATE WITH ANOTHER ELEMENT, THE FIRST ELEMENT, AS A COMMAND NEXUS, SEEKS TO OBTAIN INTERCONNECTION CONTROL AND THEN TRANSMITS A COMMAND AND ADDRESS FROM ONE MEMORY POSITION TO THE OTHER ELEMENT WHEN IT RECEIVES INTERCONNECTION CONTROL. THE CHECK IS THEN ABANDONED UNLESS THE FIRST ELEMENT MUST SEND DATA TO THE OTHER ELEMENT, IN WHICH CASE THE DATA IS SENT IMMEDIATELY. IF THE DATA IS TO BE RECOVERED, THE OTHER ELEMENT RECOVERES THE DATA, REQUESTS THE INTERCONNECTION CHECKOUT AND, WHEN GETTING IT, TRANSMITS THE DATA OVER THE INTERCONNECTION WITH IDENTIFICATION OF THE FIRST ELEMENT. IT THEN RECOVERES THE DATA FROM THE INTERCONNECTION WHEN IT RECOGNIZES ITS OWN IDENTIFICATION. IF THE OTHER ITEM IS A MEMORY ITEM, IT ALSO CONTAINS A STORAGE FILE FOR STORING COMMANDS AND DATA IF IT IS ALREADY RESPONDING TO ANOTHER ITEM'S COMMAND. C. APPLICATIONS IN THE FIELD OF COMPUTING.
