Abstract

Dispositif de détection et de correction d'erreur hors-cycle de transmission de données d'une mémoire de commande à une unité centrale de traitement de données. Le dispositif comprend un premier moyen pour extraire un groupe de données de la mémoire et le transférer à un tampon instruction de l'unité centrale et à un circuit de détection et de correction d'erreur, et un second moyen pour envoyer les données corrigées au tampon d'instruction en cas d'erreur corrigible détectée par le circuit de détection, ledit circuit de détection et de correction d'erreur comprenant un moyen pour engendrer un signal d'arrêt en cas d'erreur non corrigible détectée par ce circuit. Application à la détection et à la correction d'erreurs multiples.
