Abstract

L'invention concerne l'informatique. Un dispositif informatique comprend notamment un processeur central, une mémoire, et un canal de données rapide 12A, 12B, qui permet de réaliser des transferts de données directs entre les dispositifs périphériques externes et la mémoire, en réduisant au minimum le temps d'immobilisation du processeur central. Application aux ordinateurs.
