Title (EN) SERIAL BUS WIDTH EXPANSION ON A DYNAMIC BASIS
(FR) EXTENSION DE LARGEUR DE BUS SÉRIE SUR UNE BASE DYNAMIQUE
Abstract:
(EN) Systems, methods, and apparatus are described that enable a serial bus to be operated in one or more modes that employ additional wires for communicating data. An apparatus has a bus including a first lane and a second lane, a plurality of devices coupled to the bus and, in a first mode of operation, the plurality of devices is configured to exchange data in a signal transmitted on the first lane in accordance with timing provided by a clock signal transmitted on the second lane. The apparatus may include one or more additional lanes connecting two or more devices in the plurality of devices, the two or more devices being configured to use the first lane and at least one of the additional lanes for data transmissions in a second mode of operation.
(FR) L'invention concerne des systèmes, des procédés et un appareil qui permettent d’utiliser un bus série dans un ou plusieurs modes qui emploient des fils supplémentaires pour communiquer des données. L'appareil comporte un bus comprenant une première voie et une seconde voie, ainsi qu’une pluralité de dispositifs couplés au bus. Dans un premier mode de fonctionnement, la pluralité de dispositifs est configurée pour échanger des données dans un signal transmis sur la première voie conformément à la valeur de temps fournie par un signal d’horloge transmis sur la seconde voie. L'appareil peut comprendre une ou plusieurs voies supplémentaires reliant au moins deux dispositifs de la pluralité de dispositifs, les au moins deux dispositifs étant configurés pour utiliser la première voie et au moins une des voies supplémentaires pour les transmissions de données dans un second mode de fonctionnement.
