Patent

CA 2370632

An entertainment apparatus includes a storage unit which stores a device driver for a peripheral device outside a kernel. In order to make the peripheral device operable, a CPU causes an I/O processor to execute the device driver based on a remote procedure call. Data transfer between the peripheral device and the CPU is performed by a direct memory access according to a communication protocol which is commonly used at least in the apparatus.

L'invention concerne un appareil de divertissement comprenant un support stockant un pilote de périphérique destiné à un dispositif périphérique à l'extérieur d'un noyau. Afin que le dispositif périphérique fonctionne, une unité centrale amène un processeur E/S à exécuter le pilote de périphérique en fonction d'une procédure d'appel à distance. Le transfert de données entre le dispositif périphérique et l'unité central est réalisé par un accès mémoire direct suivant un protocole de communication couramment utilisé, du moins dans l'appareil.
