Abstract:
1. A motion compensation module for use in a video encoder for encoding a video input signal that includes a sequence of images that are segmented into a plurality of macroblocks, the motion compensation module comprising: a shared memory; a motion search module, coupled to the shared memory, that generates a motion search motion vector for a plurality of subblocks for a plurality of partitionings of a macroblock of a plurality of macroblocks and generates a selected group of the plurality of partitionings and stores the selected group of partitionings and the corresponding motion search motion vectors in the shared memory; and a motion refinement module, coupled to the motion search module, that retrieves the selected group of partitionings and the corresponding motion search motion vectors from the shared memory, that generates a refined motion vector for the plurality of subblocks for the selected group of the plurality of partitionings of the macroblock of the plurality of macroblocks, based on the motion search motion vector for each of the plurality of subblocks of the macroblock of the plurality of macroblocks.
