Abstract

L'OBJET DE L'INVENTION CONCERNE UNE ADDITION AU BREVET PRINCIPAL CONCERNANT UN SYNTHETISEUR POLYPHONIQUE NUMERIQUE DE SIGNAUX PERIODIQUES. L'ENSEMBLE DES DONNEES NECESSAIRES AU CALCUL DES ECHANTILLONS DES DIFFERENTS SIGNAUX PERIODIQUES, EST CONTENU DANS UN ENSEMBLE DE MEMOIRES ORGANISEES EN BLOC DE MOTS DISPOSES EN PARALLELE. CES MEMOIRES SONT ASSOCIEES A DES MOYENS DE LECTURES DE BLOCS SELON UN ENCHAINEMENT DETERMINE, UNE PLURALITE DE GENERATEURS DE SIGNAUX RECTANGULAIRES ET DES MOYENS DE CALCUL ET DE CONVERSION ANALOGIQUE DES ECHANTILLONS. SELON L'INVENTION, LES BLOCS SONT REPARTIS EN GROUPES; CHAQUE GROUPE COMPORTANT UN BLOC PRINCIPAL CONTENANT LES DONNEES COMMUNES A PLUSIEURS SIGNAUX ET AU MOINS UN OU PLUSIEURS BLOCS SECONDAIRES. DES POINTEURS D'ADRESSE PERMETTENT LA LECTURE DES BLOCS ET LA GENERATION DES ECHANTILLONS SUIVANT UN ENCHAINEMENT QUI DEPEND DE L'ETAT DES GENERATEURS. APPLICATION AUX INSTRUMENTS DE MUSIQUE ELECTRONIQUES.
