  • Multi-slot multi-point audio interface
    Patent number: 9436633
    Abstract: An apparatus includes multiple media processing modules and a control unit. The media processing modules are configured to exchange digital media signals over a shared bus. The control unit is configured to determine a desired connectivity scheme among the media processing modules, to adaptively define, based on the desired connectivity scheme, connections that transfer the media signals among the media processing modules over the shared bus, and to instruct the media processing modules to establish the connections, by communicating with the media processing modules over a control interface that is independent of the shared bus.
    Type: Grant

  • Method and apparatus for power reduction
    Patent number: 9048790
    Abstract: Aspects of the disclosure provide an audio amplification system. The audio amplification system includes an amplifier configured to amplify an audio signal, and a power supply module external to the amplifier that is configured to provide to the amplifier a supply voltage having a voltage level that is selected from at least two possible voltage levels based on an output volume level for the audio signal. In an example, the amplifier is a Class AB amplifier.
