Abstract

Abstract Translated from French Ce dispositif d'adressage est prévu pour fournir à une mémoire (10) des codes d'adresse provenant d'un registre principal (20) à contenu variable auquel sont associés d'une part un circuit d'incrémentation (38) pour faire évoluer le contenu du registre principal et d'autre part un circuit de chargement (22); il comporte deux registres auxiliaires (30) (35) l'un pour contenir la valeur minimum que peut atteindre le contenu du registre principal et l'autre pour contenir la valeur maximum que peut atteindre le contenu du registre principal et aussi un circuit de comparaison (37) pour tester le contenu du registre principal; le circuit de chargement coopérant avec le circuit de comparaison est conçu pour charger le registre principal avec la valeur minimum lorsqu'il contient la valeur maximum et avec la valeur maximum lorsqu'il contient la valeur minimum. This addressing device is intended to supply a memory (10) with address codes coming from a main register (20) with variable content to which are associated on the one hand an incrementing circuit (38) for changing the content of the main register and on the other hand a loading circuit (22); it comprises two auxiliary registers (30) (35) one to contain the minimum value that the content of the main register can reach and the other to contain the maximum value that the content of the main register can reach and also a comparison circuit (37) to test the content of the main register; the loading circuit cooperating with the comparison circuit is designed to load the main register with the minimum value when it contains the maximum value and with the maximum value when it contains the minimum value. Application aux systèmes à microprocesseur. Application to microprocessor systems.
