Abstract
A system comprises a source block buffer and a plurality of hardware motion estimation search processing units in communication with the source block buffer. The source block buffer is configured to store at least a portion of a source block of a source frame of a video. The plurality of hardware motion estimation search processing units are configured to perform at least a portion of a motion estimation for the source block at least in part in parallel across a plurality of different reference frames of the video. Each of the hardware motion estimation search processing units is configured to be assigned a different one of the plurality of different reference frames and is configured to compare at least the portion of the source block with a portion of the assigned one of the different reference frames.
