Abstract: This application discloses a data processing method. A first apparatus obtains a first feature of a first data block in storage space. The first feature includes a read/write feature related to the first data block and a read feature of a second data block adjacent to the first data block. The first apparatus inputs the first feature into an access frequency prediction model, to obtain access frequency of the first data block. The access frequency of the first data block is used to determine a type of the first data block. To be specific, in embodiments of this application, future access frequency of the first data block is predicted by using a multidimensional feature of the first data block (the read/write feature of the first data block and a read feature of an adjacent data block).

Abstract: The present disclosure relates to image rendering methods apparatuses, and electronic devices. One example method includes obtaining, by a central processing unit (CPU), an image command stream used to render an image frame, comparing the image command stream with a previous image command stream, and, when a same drawing command exists in the two image command streams, instructing a graphics processing unit (GPU) to render the image frame based on a previously generated drawing target.

Abstract: This application relates to the field of graphics rendering technologies, and specifically discloses a graphics rendering method and a related apparatus. A central processing unit CPU captures an instruction stream of a graphics processing unit GPU to obtain vertex data required by the GPU for graphics rendering; the CPU performs primitive processing such as coordinate transformation and clipping on the obtained vertex data to obtain vertex data within a field of view of a user; and the CPU sends the vertex data within the field of view of the user to the graphics processing unit GPU, so that the GPU performs graphics rendering processing based on the vertex data processed by the CPU. In technical solutions provided in this application, load of the GPU can be reduced during graphics rendering.

Abstract: A data processing method, a related device, and a system are provided. The method executed by a first network device includes receiving PDH frame data; loading the PDH frame data and a stuffing bit into a virtual container to obtain the virtual container that includes the PDH frame data, where the stuffing bit in the virtual container carries information about a clock frequency difference between a clock frequency of the Ethernet and a clock frequency of the PDH frame data; and performing virtual-container PWE3 encapsulation on the virtual container to obtain a virtual-container PWE3 packet. In at least some embodiments, difficulty in recovering the clock frequency of the PDH frame data when the PDH frame data is transmitted in the Ethernet is reduced, clock frequency jitters and drifts caused by the clock frequency recovery are reduced, and user experience is improved.

Abstract: Embodiments of this application provide a rendering method and apparatus, and the like. The method includes: A processor (which is usually a CPU) modifies a rendering instruction based on a relationship between a first frame buffer and a second frame buffer, so that a GPU renders a rendering job corresponding to the first frame buffer to the second frame buffer based on a new rendering instruction. In this application, render passes of one or more frame buffers are redirected to another frame buffer. In this way, memory occupation in a rendering process of an application program is effectively reduced, bandwidth of the GPU is reduced, and power consumption can be reduced.
