摘要：A memory access control device and method has a cache memory having aplurality of cache areas, each for storing image data of one macroblock, and a cache tablehaving a plurality of table areas, corresponding to the plurality of cache areas, each for

storing a validity flag indicating validity or an invalidity flag indicating invalidity of imagedata in a corresponding cache area and an in-frame address of image data of onemacroblock stored in the corresponding cache area. A data request processor receives adata request including specification of an in-frame occupation region of requested imagedata from the image processor, determines target image data of at least onemacroblock required to process the requested image data according to the in-frameoccupation region of the requested image data, acquires the target image data from thecache memory, processes the requested image data using the acquired target imagedata, and outputs the processed image data to the image processor.
