  • Patent number: 9112520
    Abstract: A transmission interface includes a first pin, a second pin, a conversion unit, and a decoding unit. The conversion unit receives a serial input data stream via the first pin and receives a serial clock via the second pin. The conversion unit converts the serial input data stream to parallel input data and converts the serial clock to a parallel clock. The serial input data stream has a full swing form. The decoding unit receives and decodes the parallel input data and generates an input data signal according to the decoded parallel input data.
    Type: Grant

  • Patent number: 8207973
    Abstract: An electronic device is disclosed. The electronic device comprises a transmitter, a converter, and a receiver. The transmitter transmits data and a control signal. The converter receives the control signal from the transmitter and converts the control signal. The receiver receives the data from the transmitter via a data bus isolated from the converter and receives the converted control signal from the converter. The data transmitted from the transmitter is directly electrically connected to the receiver.

  • Patent number: 8194146
    Abstract: An apparatus for capturing and storing real-time images is provided. A camera module records frames corresponding to sensed light, outputs pixel data of the frames on a data bus, and generates synchronization control signals to control the synchronized transmission of the frames. An interrupt controller receives the synchronization control signals and correspondingly generates interrupt signals. A processing unit receives the interrupt signals, fetches the pixel data of the frames on the data bus according to at least one of the interrupt signals, and stores the fetched pixel data in a memory device.

  • Patent number: 7937520
    Abstract: The invention discloses a general purpose interface controller, including a slave interface controller and a master interface controller, used to exchange data among master devices and slave devices in an electronic device. The slave interface controller receives data and a first control signal from one of the master devices, and converts the first control signal to a request signal. The master interface controller receives the data and the request signal from the slave interface controller, converts the request signal to a second control signal recognized by at least one of the slave devices, and forwards the data and the second control signal to the slave device.
