Abstract: A data processing method, a device, a direct memory access (DMA) controller, and a computer readable storage medium are provided. The method includes acquiring feature information and parameter information of an original input feature map; generating first DMA configuration information according to the feature information and the parameter information; generating second DMA configuration information according to the feature information; generating third DMA configuration information according to the feature information and the parameter information; constructing a target input feature map according to the first DMA configuration information; reading input data from the original input feature map according to the second DMA configuration information; and storing the input data into the target input feature map according to the third DMA configuration information.

Abstract: The present disclosure provides an image processing method. The method includes reading R rows of data of the image into a first storage buffer, R is an integer greater than 1; upsampling and filtering the R rows of data to obtain M rows of processed data, M is the upsampling multiple in the upsampling and filtering process, and M is an integer greater than 1. The method further includes reading a next row of data of the image into the first storage buffer after processing the R rows of data, the next row of data and the original R−1 rows of data in the first storage buffer are used as the R rows of data for the next upsampling and filtering process; and outputting the M rows of processed data.
