Abstract:
Methods, systems, apparatus, and articles of manufacture to reduce memory latency when fetching pixel kernels are disclosed. An example apparatus includes first interface circuitry to receive a first request from a hardware accelerator at a first time including first coordinates of a first pixel disposed in a first image block, second interface circuitry to receive a second request including second coordinates from the hardware accelerator at a second time after the first time, and kernel retriever circuitry to, in response to the second request, determine whether the first image block is in cache storage based on a mapping of the second coordinates to a block tag, and, in response to determining that the first image block is in the cache storage, access, in parallel, two or more memory devices associated with the cache storage to transfer a plurality of image blocks including the first image block to the hardware accelerator.
