The present disclosure relates to a method for computing, computing device and computer-readable storage medium. The method includes: determining a pixel block set in a cache, a first pixel block in the pixel block set comprising an m×n pixel matrix having a first padding setting related to the original pixel data, the m and n being positive integers; and storing the determined pixel block set in a buffer to enable a second pixel block to be read from the buffer based on the buffer initial address of the first pixel block and an address offset associated with the second pixel block, wherein the second pixel block has a second padding setting related to the original pixel data, and the first padding setting and the second padding setting have the same offset amount in a first direction relative to the original pixel data.
