Abstract

L'invention concerne un dispositif pour le traitement des erreurs, dans une installation de traitement de données à commande microprogrammée. Dans une installation comportant une mémoire de commande registrable WCM et une mémoire morte ROM reliée à un registre d'adresse de microprogramme MPAR et à une mémoire d'opérations élémentaires EO-M ainsi qu'à un dispositif de comptage progressif-régressif Z1, Z2, les cases de mémoire sont adressées par le dispositif de comptage qui reçoit les signaux de comptage dérivés de la cadence, lors du fonctionnement normal de l'installation et des impulsions déclenchées par un commutateur en cas de fonctionnement défectueux de cette dernière, la mémoire EO-M étant reliée à un panneau de diodes LED pour l'affichage optique d'une adresse lue de microprogramme. Application notamment aux installations de traitement des données à localisation automatique d'erreurs non corrigeables.The invention relates to a device for processing errors, in a data processing installation with microprogrammed control. In an installation comprising a WCM registrable control memory and a ROM read-only memory connected to an MPAR firmware address register and to an elementary operations memory EO-M as well as to a progressive-regressive counting device Z1, Z2 , the memory slots are addressed by the counting device which receives the counting signals derived from the rate, during normal operation of the installation and from the pulses triggered by a switch in the event of faulty operation of the latter, the EO memory -M being connected to an LED panel for optical display of a read firmware address. Application in particular to data processing installations with automatic location of non-correctable errors.
