Abstract

CE DISPOSITIF EST DESTINE A SYNCHRONISER SUR UNE HORLOGE EXTERNE LES CYCLES DE TRAVAIL D'UN DISPOSITIF NUMERIQUE COMPRENANT UNE UNITE DE CALCUL ET UNE MEMOIRE A CIRCULATION QUI DOIT FOURNIR A CHAQUE CYCLE UNE SEQUENCE DE COEFFICIENTS DANS UN ORDRE DETERMINE. LE DISPOSITIF DE L'INVENTION COMPORTE DES CIRCUITS DE COMMUTATION POUR FAIRE CIRCULER LES COEFFICIENTS DANS LA MEMOIRE SOIT EN SERIE, SOIT PAR MOT, DES MOYENS POUR FOURNIR UNE HORLOGE-MOT, DES MOYENS POUR FORMER DES CYCLES DE TRAVAIL EN SYNCHRONISME AVEC L'HORLOGE-MOT ET POUR DECLENCHER CHAQUE CYCLE DE TRAVAIL A CHAQUE TRANSITION CARACTERISTIQUE DE L'HORLOGE EXTERNE SE PRODUISANT APRES LA FIN DE CHAQUE CYCLE. ENFIN LES CIRCUITS DE COMMUTATION SONT COMMANDES POUR FAIRE CIRCULER LA SEQUENCE DE COEFFICIENTS EN SERIE UNE FOIS AU COURS D'UN CYCLE ET POUR FAIRE CIRCULER LES COEFFICIENTS PAR MOT LE RESTE DU TEMPS. APPLICATION: RECEPTEUR DE TYPE NUMERIQUE POUR LA TRANSMISSION DE DONNEES.
