Abstract: Disclosed are a data loading method and apparatus for a convolution operation, a computer device, a storage medium and a computer program product. The method includes: splitting a feature image to be loaded into the cache unit into a plurality of sub-feature images; determining a target cache line corresponding to each of the sub-feature images in each of the cache lines according to a positional relationship of each of the sub-feature images in the feature image; wherein target cache lines corresponding to at least two sub-feature images with the same positional relationship are located in the same cache set, and target cache lines corresponding to at least two sub-feature images with an adjacent positional relationship are located in different cache sets; loading a data content of each of the sub-feature images into the target cache line corresponding to each of the sub-feature images.

Abstract: The present disclosure relates to a texture sampling method and apparatus based on merge processing of texel requests. The present disclosure merges target texel requests in the same cache line together, which reduces the number of cache hit tests. A pressure on the cache of next level to process texel requests may be significantly reduced, and the speed of texture sampling may be increased. The method includes: creating a texture sampling request, where the texture sampling request includes a pixel to be processed; obtaining multiple target texel requests based on pixel coordinates of the pixel to be processed; performing a merge processing on the multiple target texel requests according to a preset rule, and obtaining a merge table of texel requests; sequentially performing cache hit tests on the multiple target texel requests to obtain target texels based on the valid cache lines in the merge table of texel requests.

Abstract: The present disclosure relates to the computer technology and provides a method and a device for selecting a cache line to be replaced, and a storage medium. In the present disclosure, a blocking state binary tree is added to replace a replacement state binary tree, and a cache line to be replaced is selected based on the blocking state binary tree and a usage state binary tree, such that the earliest cache line, acting as the cache line to be replaced, can be accurately selected from the replaceable cache lines in a blocking cache.
