Abstract

Dispositif de chargement et/ou déchargement de clés dans un registre de clés. Des circuits de chargement et/ou déchargement, commandés par les circuits de commande décodent les instructions à exécuter, permettent soit de ne charger ou de ne décharger qu'une des sections du registre de clés, correspondant à un mode d'adressage particulier du système, soit de charger ou décharger l'ensemble du registre. Ces circuits acroissent les possibilités d'adressage et la sécurité des systèmes de traitement de données.
