  • Patent number: 8254728
    Abstract: In one embodiment, the present invention is a system for organizing data flow for two dimensional digital image processing. The system includes a memory access module for accessing an external memory containing image data to be processed, and a data flow organizer module for preparing a data stream from the input image data accessed by the memory access module. The data flow organizer module predicts future data needed for processing, and the memory access module pre-fetches the predicted data from the memory. A data processing module processes the pre-fetched data from the data flow organizer module. Address generation for accessing the memory is performed independent and in parallel with processing the pre-fetched data.
