  • Patent number: 10331580
    Abstract: A peripheral interface multiplexing method. The method includes receiving, by using a first pin in a peripheral interface of user equipment, a coded signal sent by an external device, where the coded signal includes a first electrical characteristic value of the first pin; decoding the coded signal to obtain a decoded signal, where the decoded signal includes a control signal that corresponds to the first electrical characteristic value of the first pin, and the control signal is used to control the peripheral interface to transmit a target signal that a user requests to transmit; and controlling, according to the control signal, a pin that is in the peripheral interface and used for signal transmission to transmit the target signal. Therefore, communications interfaces of user equipment can be extended without increasing a quantity of peripheral interfaces, so that the user equipment provides more communications manners, and user experience is improved.

  • Patent number: 10312927
    Abstract: Certain aspects of the present disclosure provide methods and apparatus for calibrating time-interleaved analog-to-digital converter (ADC) circuits and generating a suitable signal for such calibration. Certain aspects provide a signal generator for calibrating a time-interleaved ADC circuit having a plurality of channels. The signal generator generally includes a pattern generator configured to receive a periodic signal and to output a bitstream based on the periodic signal and a conversion circuit having an input coupled to an output of the pattern generator and configured to generate a waveform based on the bitstream. The bitstream has a bit pattern with a total number of bits that shares no common factor with a number of the channels and includes a relatively lower frequency component combined with a relatively higher frequency component.

  • Publication number: 20190130875
    Abstract: The present disclosure relates to example processing methods and devices. In one example method, resolution of each layer of multiple layers of an application program are determined. Resolution of a first layer is lower than resolution of another layer. The multiple layers are created according to the resolution of each layer. Rendering processing is performed on the multiple layers. Scaling processing is performed on a second layer obtained after the rendering processing. The determined resolution of the second layer is different from resolution of a preset area displaying the second layer on a display screen. Resolution of the second layer obtained after the scaling processing is the same as the resolution of the preset area. A layer other than the second layer obtained after the rendering processing is composited with the second layer obtained after the scaling processing. An image obtained after the composition is output to the display screen.
