A method includes determining a cache width of a cache of a processing device and determining a block size of image data processed by the processing device. The method further includes prefetching a data block of image data from a memory component to a plurality of cache lines of the cache based on the cache width and the block size. A processing system includes a memory component, a cache and an execution pipeline coupled to the memory component and the cache. The execution pipeline is to determine a cache width of the cache, determine a block size of image data stored at the memory component, and prefetch a data block of image data from a memory component to a plurality of cache lines of the cache based on the cache width and the block size.
