Abstract

Dans le domaine des ordinateurs embarqués, l'invention porte sur un ordinateur de réseau basé sur un circuit intégré prédiffusé programmable (FPGA) qui surmonte les désavantages qui sont que l'ordinateur antérieur a une consommation électrique plus élevée, gaspille davantage de matériel et n'est pas commode pour étendre la fonction du processeur. A l'intérieur de la puce FPGA se trouve un bus d'échange, un contrôleur de bus, et deux modules ou plus parmi un module de traitement USB, un module de carte vidéographique (VGA), un module Ethernet, un module audionumérique ou un contrôleur de mémoire. Le bus d'échange transmet les données de chaque module fonctionnel de la puce FPGA. Le contrôleur de bus est connecté au bus d'échange pour commander le bus d'échange afin de transmettre des données. Cette invention réduit la complexité du système et la consommation d'énergie de l'ordinateur embarqué, et confère à l'ordinateur de réseau une bonne capacité d'extension.
