Abstract

L'INVENTION CONSISTE A DIVISER LA MEMOIRE DE MICROPROGRAMME MPS D'UN MICRO-ORDINATEUR MICROPROGRAMMABLE EN 2 ZONES AU MOYEN DESQUELLES LES INSTRUCTIONS DE N EB ENREGISTREES DANS LA MEMOIRE DE PROGRAMME PS PEUVENT ETRE INTERPRETEES SELON 2 MICROPROGRAMMES DIFFERENTS. LE RANG D'UN MAXIMUM DE 2 INSTRUCTIONS SUCCESSIVES DE N EB, QUI CORRESPONDENT A UNE MACRO-INSTRUCTION ECRITE EN UN LANGAGE EVOLUE, EST INDIQUE AU SEQUENCEUR DE MICRO-PROGRAMME MCU PAR UN ENSEMBLE DE M BISTABLES FFM COMMANDES PAR LA MEMOIRE MPS ET CORRESPOND A L'ADRESSE DE LA ZONE DE MPS A UTILISER POUR CHAQUE INSTRUCTION. LE REPERTOIRE DE MACROINSTRUCTIONS EST AINSI ETENDU A 2 POUR UN NOMBRE D'INSTRUCTIONS LIMITE A 2 DANS LA MEMOIRE DE PROGRAMME PS, CAR DES MACROINSTRUCTIONS DIFFERENTES PEUVENT ETRE FORMEES PAR LES MEMES INSTRUCTIONS PRISES DANS UN ORDRE DIFFERENT.
