Abstract
An apparatus performs motion estimation based on an average of previous field references in a flexible, yet high performance manner. The apparatus has a command memory for storing a motion estimation command list segment which in turn contains a search command for specifying a merged search operation over one or more search positions. The apparatus also has a score memory for storing the result of each merged search operation. The score memory is initialized when the merged search operation is initiated. During the search operation, the score memory accumulates the result of each search position. The apparatus also has a search engine connected to the command memory and to the score memory for determining from the score memory a search position with the lowest score. The search engine then generates dual prime motion estimation outputs in the form of motion estimation result list segments.
