摘要： This application provides a data transmission method and an electronic device. The method may be applied to an electronic device configured with a plurality of input devices (for example, camera modules). One uplink interface and one downlink interface are deployed on each input device of the electronic device. The uplink interface is connected to a processor or an upper-level input device, and the downlink interface is connected to a lower-level input device or is not connected. A processing module in each input device may process image data collected by the current-level device and data sent by a lower-level input device connected to a downlink interface, and then transmit processed data to the processor or an upper-level input device through an uplink interface. In this way, the plurality of input devices are connected in a cascade manner, and only one of the plurality of input devices needs to be connected to the processor. Therefore, a quantity of interfaces and a quantity of signal pins between the processor and the plurality of input devices are reduced. In addition, adding or subtracting an input device is easy to operate.

摘要： An electronic system (200), a camera module (190, or 210), a SoC (110, or 220), and an electronic device (100) are disclosed. The camera module (210) includes a first bidirectional interface (2101). The SoC (220) includes a second bidirectional interface (2201). The second bidirectional interface (2201) is coupled to the first bidirectional interface (2101), and the first bidirectional interface (2101) and the second bidirectional interface (2201) support a same bidirectional data communication interface protocol. The camera module (190, or 210) can obtain image data, and perform first image processing on the image data to obtain a first image processing result. The SoC (110, or 220) can perform second image processing on the first image processing result to obtain a second image processing result. In this way, the camera module (210) and the SoC (220) are connected to each other through the bidirectional interfaces (2101, and 2201) that support the bidirectional data communication interface protocol, to improve flexibility of an interface between the camera module (190, or 210) and the SoC (110, or 220), so that the camera module (190, or 210) flexibly processes the image data.

摘要： A communication circuit and an electronic device are provided. The communication circuit includes a sending apparatus, a communication line, and a receiving apparatus. The sending apparatus is connected to the receiving apparatus through the communication line. A first power supply management unit is coupled to a first direct current maintaining unit, and the first direct current maintaining unit is coupled to a first end of the communication line. A second power supply management unit is coupled to a second direct current maintaining unit, and the second direct current maintaining unit is coupled to a second end of the communication line. The first power supply management unit controls the first direct current maintaining unit to be powered on, and controls the first direct current maintaining unit to maintain a power-on state. The first direct current maintaining unit maintains a direct current voltage at the first end of the communication line as a first preset voltage. The second power supply management unit controls the second direct current maintaining unit to be powered on, and controls the second direct current maintaining unit to maintain a power-on state. The second direct current maintaining unit maintains a direct current voltage at the second end of the communication line as a second preset voltage.
