1. a kind of DDR physical layer data processing methods, which is characterized in that the method includes:

  • Receive selection signal, enabled control signal generated according to the selection signal, according to the enabled control signal control intoEnter the transmission mode of the data-signal in DDR physical layer transmissions channel;

    If the selection signal received is first choice signal, the first enabled control is generated according to the first choice signalSignal generates the second enabled control if the selection signal received is the second selection signal according to second selection signalSignal processed;

    The data-signal for entering DDR physical layer transmissions channel according to the described first enabled control signal control is unidirectionally passedIt is defeated;

    The data-signal for entering DDR physical layer transmissions channel according to the described second enabled control signal control carries out two-way biographyIt is defeated, so as to the transmission direction of the data-signal be controlled according to the second interface module that second enable signal selects, in numberIt is single along data-signal and double conversions between data-signal according to the data-signal is carried out in segment, wherein the dataSegment provides differential clocks for the list along data-signal, and the edge of the differential clocks therein is with described pair along data-signalRising edge and failing edge justified.
