Abstract
A hardware video encoder includes a first inter-picture prediction search processor to perform at least one coarse search at a designated block size. The at least one coarse search utilizes a down-sampled version of an image to determine motion vectors. A second inter-picture prediction search processor performs motion vector refinement searches on pixels of the image for multiple block sizes. Searches of at least one block size utilize the motion vectors. A third inter-picture prediction search processor performs fractional pixel motion vector refinement searches on interpolated values of the pixels of the image for multiple block sizes in parallel.
