Title (EN) HIGH BANDWIDTH SOUNDWIRE MASTER WITH MULTIPLE PRIMARY DATA LANES
(FR) MAÎTRE SOUNDWIRE À GRANDE LARGEUR DE BANDE AVEC DE MULTIPLES VOIES DE DONNÉES PRIMAIRES
Abstract:
(EN) System, methods and apparatus are described that can improve available bandwidth on a SoundWire bus without increasing the number of pins used by the SoundWire bus. A method performed at a master device coupled to a SoundWire bus includes providing a clock signal by a first master device over a clock line of a SoundWire bus to a first slave device and a second slave device coupled to the SoundWire bus, transmitting first control information from the first master device to the first slave device over a first data line of the SoundWire bus, and transmitting second control information from the first master device to the second slave device over a second data line of the SoundWire bus. The first control information may be different from the second control information and is transmitted concurrently with the second control information.
(FR) La présente invention concerne un système, des procédés et un appareil qui peuvent améliorer la largeur de bande disponible sur un bus SoundWire sans augmenter le nombre de broches utilisées par le bus SoundWire. Un procédé réalisé au niveau d'un dispositif maître couplé à un bus SoundWire inclut la fourniture d'un signal d'horloge par un premier dispositif maître sur une ligne d'horloge d'un bus SoundWire à un premier dispositif esclave et à un second dispositif esclave couplés au bus SoundWire, la transmission de premières informations de commande du premier dispositif maître au premier dispositif esclave sur une première ligne de données du bus SoundWire, et la transmission de secondes informations de commande du premier dispositif maître au second dispositif esclave sur une seconde ligne de données du bus SoundWire. Les premières informations de commande peuvent être différentes des secondes informations de commande et sont transmises simultanément aux secondes informations de commande.
