Abstract

A.SYSTEME DE TRAITEMENT DE DONNEES NUMERIQUES COMPRENANT UNE UNITE CENTRALE REPONDANT A DIVERSES INSTRUCTIONS CARACTERISEES EN CE QU'ELLES SONT DE LONGUEUR VARIABLE. B.CHAQUE INSTRUCTION COMPREND UN CODE D'OPERATION. CERTAINES INSTRUCTIONS COMPRENNENT EGALEMENT UN OU PLUSIEURS SPECIFICATEURS D'OPERANDE. CHAQUE SPECIFICATEUR D'OPERANDE PEUT COMPRENDRE UN OU PLUSIEURS MULTIPLETS DE DONNEES. CHAQUE INSTRUCTION PASSE DANS UNE MEMOIRE TAMPON D'INSTRUCTIONS. LES CIRCUITS DE CONTROLE DE L'UNITE CENTRALE DECODENT LE CODE D'OPERATION ET, EN SUCCESSION, CHAQUE MULTIPLET SPECIFICATEUR D'OPERANDE. LES SPECIFICATEURS D'OPERANDE ET LES INFORMATIONS EXTRAITES DU CODE D'OPERATION CONCERNANT CHAQUE SPECIFICATEUR D'OPERANDE SONT COMBINES POUR OBTENIR L'ADRESSE DANS LAQUELLE L'OPERANDE DOIT ETRE RECUPEREE OU A LAQUELLE UNE OPERANDE DOIT ETRE TRANSFEREE. LA REPONSE DE L'UNITE CENTRALE A UNE INSTRUCTION DEMANDANT L'ADDITION DE DEUX TERMES SITUES DANS DES PREMIERE ET SECONDE POSITIONS DE MEMOIRE ET LE STOCKAGE DE LA SOMME DANS UNE TROISIEME POSITION ET DES INSTRUCTIONS D'APPEL DE SOUS-ROUTINE ET LE RENVOI DE LA SOUS-ROUTINE A LA SOUS-ROUTINE D'APPEL SONT DECRITS. C.APPLICATIONS DANS LE DOMAINE DE L'INFORMATIQUE.
