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 based upon how the source area and the destination area overlap in the first memory.
