摘要： A frame rate adjustment method, apparatus and device, a computer-readable storage medium and a computer program product. The method includes: acquiring running data of a client during running in a foreground when the client in the terminal device supports dynamic frame rate switching; determining a running scenario of the client based on the running data; determining a target running frame rate of the client based on the running scenario; and performing, by the client, image outputting according to the target running frame rate, and triggering an operating system of the terminal device to adjust a refresh rate of a screen according to the target running frame rate.

摘要： The present teaching relates to method, system, medium, and implementations for data transfer in LED display. A signal signaling a timing for a next data transfer is received. In response to the signal, a next data transfer instruction is obtained that instructs reading a bit-based image block of an image from a memory. The bit-based image block is transferred, according to the next data transfer instruction, from the memory via a bus connected thereto, to one of a pair of alternate buffers pointed to by a write buffer pointer. Then, the write buffer pointer is toggled to point to another of the pair of alternate buffers and the process repeats. The bit-based image blocks alternately stored in the buffers are later retrieved and displayed on the LED display.

摘要： The present disclosure relates to a signal processing device and an image display apparatus including the same. The signal processing device includes a synchronizer configured to perform Fourier transform based on the received baseband signal, and an equalizer configured to extract a pilot signal from a signal from the synchronizer, to calculate a channel transfer function value of the extracted pilot signal, and to selectively perform time interpolation based on the calculated channel transfer function value. Thus, time interpolation is selectively performed based on the channel.

摘要： The invention provides an image output device coupled to a first and second signal source and a method thereof. The image output device includes memories configured to store frame image data respectively, a source selection circuit coupled to the first and second signal sources and the memories and configured to choose to store a first frame image data transmitted by the first or second signal source in one of the memories according to a working state of the first signal source, and an image output circuit coupled to the memories and the source selection circuit and configured to output the first frame image data stored in one of the memories. The image output device may rapidly switch to a backup signal source when the signal source is unstable to achieve fast switching and perfect connection.

摘要： Disclosed are an image data reading method and apparatus, an electronic device, and a readable storage medium, relating to the technical field of LED image display. The image data reading method includes: storing image data in each row of image blocks into a number of v storage blocks, where each of the v storage blocks stores a number of h rows, each row of data including image data stored at a same position of each group in a same row of every image block; and sequentially outputting from each of the v storage blocks by: sequentially reading each row of the image data in a vertical order, and simultaneously outputting the image data stored at the same position.

摘要： Systems, apparatuses, and methods for enabling indirect chaining of command buffers are disclosed. A system includes at least first and second processors and a memory. The first processor generates a plurality of command buffers and stores the plurality of command buffers in the memory. The first processor also generates and stores, in the memory, a table with entries specifying addresses of the plurality of command buffers and an order in which to process the command buffers. The first processor conveys an indirect buffer packet to the second processor, where the indirect buffer packet specifies a location and a size of the table in the memory. The second processor retrieves an initial entry from the table, processes a first command buffer at the address specified in the initial entry, and then returns to the table for the next entry upon completing processing of the first command buffer.

摘要： Systems, apparatuses, and methods for implementing a timestamp based display update mechanism. A display control unit includes a timestamp queue for storing timestamps, wherein each timestamp indicates when a corresponding frame configuration set should be fetched from memory. At pre-defined intervals, the display control unit may compare the timestamp of the topmost entry of the timestamp queue to a global timer value. If the timestamp is earlier than the global timer value, the display control unit may pop the timestamp entry and fetch the frame next configuration set from memory. The display control unit may then apply the updates of the frame configuration set to its pixel processing elements. After applying the updates, the display control unit may fetch and process the source pixel data and then drive the pixels of the next frame to the display.
