Abstract: Embodiments of the present disclosure provide a data accessing method, a device and a storage medium. The method includes: obtaining a first accessing request and a second accessing request for a storage device; loading first data associated with the first accessing request from a source device to a pre-allocated buffer area with a size same as a size of a single physical storage block of the storage device; determining a first part of the second data when the first size of second data associated with the second accessing request is greater than or equal to the second size of an available space of the buffer area, a size of the first part being the same as the second size; and providing the first data and the first part to a target device associated with the first accessing request and the second accessing request.

Abstract: Embodiments of the present disclosure provide a method and apparatus for extracting image data in parallel from multiple convolution windows, a device, and a computer-readable storage medium. The method includes: dividing an image into multiple groups of convolution windows, where the multiple groups of convolution windows include a first group of convolution windows and a second group of convolution windows, and each group of convolution windows include multiple convolution windows. The method further includes extracting image data in parallel from multiple convolution windows in the first group of convolution windows by using multiple data processing units, and extracting, after the extraction of image data from the first group of convolution windows is completed, image data from multiple convolution windows in the second group of convolution windows in parallel by using the multiple data processing units.
