Abstract: A field-programmable gate array (FPGA)-based FAST protocol decoding method, apparatus, and device, and a readable storage medium. The method acquires an actual XML template in real time and analyzes the actual XML template, generates a FAST protocol intermediate representation, and determines, according to preset decoding parameters, the maximum number of fields which are read at a single time, so as to generate a field matching state machine. Thus, the present disclosure can support a dynamically updated XML template, and allows flexible setting of the maximum number of fields according to an actual network bandwidth, and is applicable to disclosure scenarios of different network bandwidths. In a decoding process, the present disclosure realizes, by means of a field shift register and the field matching state machine, the function of reading and decoding a plurality of fields in parallel each time, significantly improving decoding efficiency.

Abstract: Provided are a data processing method and device based on a convolutional neural network. For any convolutional layer in a convolutional neural network, calculation is performed by a convolution kernel of the convolutional layer, on elements of data inputted to the convolutional layer one by one so as to obtain convoluted values of the respective elements. Each calculation obtains a convoluted value, and this convoluted value and convoluted values of elements in the same region obtained by calculation through the same convolution kernel are added together to obtain an output element of the convolution kernel corresponding to the region. In this way, an output of a convolutional layer can be obtained after all convoluted values have been calculated without having to read convoluted values from a storage apparatus, thus enhancing data processing efficiency.

Abstract: The present disclosure provides a method for determining an overdrive mapping correlation in a display panel. The method includes the following steps. First, a repeating subpixel arrangement is determined. The subpixel arrangement includes at least three sets of subpixels in the display panel. An ideal luminance value of a pattern of the subpixel arrangement is then determined. The pattern includes at least a first set of subpixels displaying a zero pixel value, a second set of subpixels displaying a first nonzero pixel value, and a third set of subpixels displaying a second nonzero pixel value, the first, second and third sets of subpixels respectively arranged one after another. The first nonzero pixel value may be different from the second nonzero gray scale value. An actual luminance value of the pattern of the subpixel arrangement is then determined. An overdrive pixel value is further determined.

Abstract: The present disclosure provides a method for determining a grayscale mapping correlation in a display panel. The method includes the following operations. First, a target first luminance value of the display panel is determined. A first set of start pixel values of a first attribute of a first grayscale value is determined based on the first grayscale value and the target first luminance value of the display panel. A first set of mapped pixel values of the first attribute mapped to the first grayscale value, and a first mapped luminance value are then determined based on the first set of start pixel values of the first attribute and a set of first target values of a second attribute. The set of first target values of the second attribute include a plurality of target chrominance values and the target first luminance value.
