Abstract

LE SYSTEME COMPREND UNE MEMOIRE PRINCIPALE RELIEE A UNE UNITE DE TRAITEMENT PAR UNE ANTEMEMOIRE COMPORTANT DES GROUPES D'EMPLACEMENTS DE MOTS, UN REPERTOIRE DE DONNEES SERVANT A MEMORISER DES ADRESSES DANS DES EMPLACEMENTS CORRESPONDANT AU NOMBRE DESDITS GROUPES, UN REPERTOIRE DE COMMANDE COMPRENANT UN NOMBRE DE BITS CORRESPONDANT AU NOMBRE DE GROUPES, ET UN TAMPON DE COMMANDE D'ENTREE POUR MEMORISER DES DEMANDES RECUES DE L'UNITE DE TRAITEMENT ET DE CIRCUITS DE COMMANDE QUI COMPRENNENT UN DECODEUR METTANT A UN ETAT PREDETERMINE UN BIT DEFINI DU REPERTOIRE DE COMMANDE QUAND LE REPERTOIRE DE DONNEES INDIQUE QUE LE MOT DEMANDE NE SE TROUVE PAS DANS L'ANTEMEMOIRE. APPLICATION AUX SYSTEMES DE TRAITEMENT MICROPROGRAMMES.THE SYSTEM INCLUDES A MAIN MEMORY LINKED TO A PROCESSING UNIT BY A MEMORY INCLUDING GROUPS OF WORD LOCATIONS, A DATA DIRECTORY SERVING TO STORE ADDRESSES IN LOCATIONS CORRESPONDING TO THE NUMBER OF SUCH GROUPS, A NUMBER OF COMMANDS, A NUMBER OF COMMANDS BITS CORRESPONDING TO THE NUMBER OF GROUPS, AND AN INPUT CONTROL BUFFER TO STORE REQUESTS RECEIVED FROM THE PROCESSING UNIT AND CONTROL CIRCUITS WHICH INCLUDE A DECODER SETTING A PREDETERMINED STATE A DEFINED BIT FROM THE CONTROL DIRECTORY WHEN THE DIRECTORY OF DATA INDICATES THAT THE REQUESTED WORD IS NOT IN THE ANTEMEMORY. APPLICATION TO MICROPROGRAMS TREATMENT SYSTEMS.
