Title (EN) SERIAL PROTOCOL FOR AGILE SAMPLE RATE SWITCHING
(FR) PROTOCOLE SERIE POUR COMMUTATION DE TAUX D'ECHANTILLONNAGE AGILE
Abstract:
(EN) The invention provides a communication protocol and serial interface having an approximately fixed interface clock and capable of accommodating a variety of communication rates. The interface employs a variable-length frame that may be expanded or reduced to obtain a desired communication rate, even though the interface clock rate is held approximately constant. The invention further provides a method for designing an agile barrier interface. In particular, the barrier clock rate is preferably selected to be an approximate common multiple of the various communication rates that the barrier interface must handle. The frame length corresponding to each communication rate may then be obtained by dividing the barrier clock rate by the Σ&Dgr; rate. Finally, the invention provides an agile barrier capable of communicating data across a serial interface at a variety of data rates and at an approximately fixed interface clock rate.
(FR) Protocole de communication et interface série à horloge d'interface approximativement fixe et permettant d'assurer une gamme de débits de communication. L'interface utilise une trame de longueur variable susceptible d'être augmentée ou réduite pour l'établissement d'un débit de communication souhaité, même lorsque la fréquence d'horloge d'interface est maintenue à un niveau à peu près constant. Par ailleurs, procédé de conception d'interface barrière agile. En particulier, on choisit de préférence une fréquence d'horloge barrière comme multiple commun approché de divers débits de communication que l'interface barrière doit manipuler. La longueur de trame correspondant à chaque débit de communication peut ensuite être déterminée par division de la fréquence d'horloge barrière par le taux S?. Enfin, barrière agile capable de transmettre des données via une interface série à divers débits de données et à une fréquence d'horloge d'interface approximativement fixe.
