Title (EN) BUS CONTROL DEVICE AND INFORMATION PROCESSING SYSTEM
(FR) DISPOSITIF DE COMMANDE DE BUS ET SYSTEME DE TRAITEMENT DE L'INFORMATION
Abstract:
(EN) A node connected ahead of a port is stored and a destination of a packet is discriminated, whereby a packet is transferred to a port which requires transfer of a packet, while a dummy signal having a lower dissipation power than at the time of packet transmission is sent to a port which does not require transfer of a packet. Thus, power consumption accompanied by the transfer of a packet to an unnecessary node is reduced in a state where bus collision is prevented.
(FR) Un noeud connecté au-delà d'un port est mémorisé, et la destination d'un paquet est discriminée. Un paquet est ainsi transféré à un port qui nécessite le transfert d'un paquet, tandis qu'un signal factice, présentant une puissance de dissipation plus faible que lors de la transmission du paquet, est envoyé à un port qui ne nécessite pas de transfert de paquets. Ainsi, la consommation de puissance accompagnée par le transfert d'un paquet à un noeud inutile est réduit dans un état dans lequel on évite toute collision de bus.
