Abstract
(EN)
A method, an apparatus, and a computer program product for data communication over a multi-wire, multi-phase interface are provided. The method may include providing a sequence of symbols to be transmitted on a 3-wire interface, each symbol in the sequence of symbols defining one of three voltage states for each wire of the 3-wire interface, driving all wires of the 3-wire interface to a common voltage state during a transition from a first transmitted symbol to a second transmitted symbol, driving each wire of the 3-wire interface in accordance with the second transmitted symbol after a predetermined delay. Each wire may be in a different voltage state from the other wires of the 3-wire interface during transmission of the each symbol. The common voltage state may lie between two of the three voltage states.

La présente invention concerne un procédé, un appareil, et un produit programme d'ordinateur pour la communication de données sur une interface multiphasée multifilaire. Le procédé peut consister à fournir une séquence de symboles devant être transmis sur une interface à 3 fils, chaque symbole dans la séquence de symboles définissant un des trois états de tension pour chaque fil de l'interface à trois fils, à entraîner tous les fils de l'interface à 3 fils dans un état de tension commun pendant une transition depuis un premier symbole transmis à un second symbole transmis, et à entraîner chaque fil de l'interface à 3 fils conformément au second symbole transmis après un délai prédéfini. Chaque fil peut être dans un état de tension différent par rapport aux autres fils de l'interface à 3 fils pendant la transmission de chaque symbole. L'état de tension commun peut se trouver entre deux des trois états de tension.
