Abstract

Le calculateur décrit utilise des fonctions de variables de commande statiques et dynamiques pour effectuer ses opérations de prise de décision, les variables dynamiques étant disponibles dans un cycle qui fait suite à la mise à disposition des variables statiques. Les tables de vérité des fonctions sont emmagasinées dans des mémoires de fonctions logiques qui sont adressées par des zones de commande de sélection de fonction logique et par les variables statiques, de manière à fournir les entrées de table de vérité qui correspondent à la fonction sélectée des variables de commande statiques. Les variables dynamiques sélectent parmi les entrées de table de vérité adressées pour fournir les signaux de décision. De préférence, les mémoires de fonctions logiques sont réalisées au moyen de circuits intégrés LSI.
