摘要： A power consumption adjustment method and apparatus are provided, to improve accuracy of frequency and voltage adjustment. The method includes: obtaining a historical running feature of a task; determining a target frequency and a target voltage based on the historical running feature of the task and a state of a voltage domain in which a processor core that is to run the task is located; and adjusting, based on the target frequency and the target voltage, a frequency and a voltage of each processor core located in the voltage domain. Frequency and voltage adjustment are performed based on the historical running feature of the task and the state of the voltage domain, to help select a frequency and a voltage that are suitable for a current running requirement of the task from a power consumption configuration currently supported by the voltage domain to run the task, to effectively improve accuracy of frequency and voltage adjustment. In addition, the task is run based on the frequency and the voltage that are suitable for the task, and therefore a task processing capability is improved.

摘要： Embodiments of this application disclose a packaging module and an electronic device. Both a first surface and a second surface of a PCB in the packaging module are covered with a molding layer, a conductive pin is electrically connected to the PCB, the conductive pin is packaged inside the molding layer along a stacking direction of the PCB and the molding layer, and the conductive pin is partially exposed on an outer surface of the molding layer. When the packaging module performs electrical interaction with another element, the PCB outputs or inputs an electrical signal by using the conductive pin. In this way, there is no need to reserve a through hole on a packaging side of the packaging module, the packaging module may be arranged at a position close to a chip, and there are short wires between the packaging module and the chip. This reduces a size of an electronic device and reduces a power distribution loss of the electronic device.

摘要： A data query method and apparatus are disclosed. The data query method and apparatus relate to the field of computer technologies, to resolve a problem of comparatively low efficiency for querying a to-be-accessed file name. The method includes: determining a target directory block including m directory entries and m file names, where the m directory entries one-to-one correspond to the m file names, and the m directory entries and the m file names are sequentially arranged according to a preset rule; determining a current first set and a current second set based on a binary search algorithm and the target directory block, where the current first set includes x consecutive file names in the m file names, the current second set includes the x file names, a first file name, and a second file name, and m ≥ x≥ 1; determining a first common prefix between the to-be-accessed file name and a file name in the current second set; comparing the to-be-accessed file name with a third file name character by character from a first character after the first common prefix; and if the to-be-accessed file name is the same as the third file name, obtaining data of a to-be-accessed file based on a directory entry corresponding to the third file name.

摘要： This application discloses a data processing method and apparatus, a computing device, and a system, and relates to the field of remote control. The method includes: A first computing device obtains first information used by a second computing device to display a first image, where the first information includes a drawing instruction, and the drawing instruction is used to render first to-be-rendered data to obtain the first image. The first computing device determines indication information of the first to-be-rendered data, and sends second information that includes the drawing instruction and the indication information to the second computing device, so that the second computing device locally obtains the first to-be-rendered data based on the indication information. In this way, the first computing device uses the indication information of the to-be-rendered data to indicate to-be-rendered data that needs to be repeatedly transmitted, to avoid repeated transmission of same to-be-rendered data. Therefore, a data volume of the to-be-rendered data carried in the drawing instruction is reduced, bandwidth and a delay of data transmission are reduced, and the second computing device can obtain, in time, information required for displaying an image to display the image, to improve user experience.
