Abstract

ENSEMBLE DE BASE DE DONNEES A RELATIONS, DANS LEQUEL LES DONNEES SONT EMMAGASINEES DANS DES TABLES. L'ENSEMBLE COMPORTE AU MOINS UNE MICRO-PLAQUETTE CI DE MEMOIRE, PAR EXEMPLE DU TYPE A BOUCLES PRINCIPALESECONDAIRES 12 DISPOSEES EN GROUPES 1, 2, ... N. LES DONNEES LUES D'UNE MICRO-PLAQUETTE SONT COMPAREES AVEC UN CRITERE DE TEST AFIN DE SELECTIONNER DES DONNEES APPROPRIEES ET UNE BOUCLE D'INDEXATION GARDE LA TRACE DES COMPARAISONS. CETTE BOUCLE CONSTITUE UNE ENTREE AU CONTROLEUR DE LA MEMOIRE DE FACON QUE PENDANT LES RECHERCHES ULTERIEURES LES COMPARAISONS NE SOIENT REALISEES QUE SUR DES DONNEES DEJA QUALIFIEES. APPLICATIONS AUX MEMOIRES A BULLES MAGNETIQUES, A SEMI-CONDUCTEUR A DISPOSITIFS A TRANSFERT DE CHARGE.
