Abstract:
An apparatus including a first memory, a second memory, and a memory interface. The first memory may be configured to store an entire image. The second memory may be configured to store a portion of the image during an image processing operation. The memory interface may be configured to transfer the portion of the image (i) from a source area of the first memory to the second memory prior to the image processing operation and (ii) from the second memory to a destination area of the first memory following the image processing operation. The memory interface may be further configured to select from among four modes of transferring image data from the source area of the first memory and to the destination area of the first memory based upon how the source area and the destination area overlap in the first memory.
