  • Publication number: 20090232201
    Abstract: A video compression system may have first and second dual-port memory devices, a third memory device, and first and second processors that may provide enhanced processing, including motion estimation. The first processor may be configured to store in the second memory device first and second video frames and to transfer sequential sets of data from the first video frame corresponding to fields of search. A second set of a plurality of adjacent macroblocks of the second video frame may be compared to macroblocks selected from the field of search. Dual-port memory devices may allow for the concurrent use of shared memory by the two processors as well as data transfer during processing.
