Abstract

L'invention concerne un dispositif mobile de communication comprenant un terminal mobile servant à communiquer avec un réseau et plusieurs terminaux d'application reliés au terminal mobile. On place une mémoire interface accessible à partir d'un bus DMA, destiné aux terminaux d'application, et un bus CPU destiné à commander, entre ces deux bus. Une unité de commande DMA commande des première et seconde sections DMA effectuant des transferts de données DMA au moyen de respectivement le bus DMA et le bus CPU. Le transfert de données entre les terminaux d'application reliés au moyen du bus DMA et une unité prédéterminée reliée au bus CPU est effectué à une vitesse élevée au moyen de la commande DMA du bus correspondant via l'interface mémoire.
