Abstract
An apparatus having a cache and a processor. The cache may be configured to (i) buffer a first subset of reference samples of a reference picture to facilitate a motion estimation of a current block and (ii) prefetch a second subset of the reference samples while a first search pattern is being tested. The first search pattern used in the motion estimation generally defines multiple motion vectors to test. The reference samples of the second subset may be utilized by a second search pattern in the motion estimation of the current block. The prefetch of the second subset may be based on a geometry of the first search pattern and scores of the motion vectors already tested. The processor may be configured to calculate the scores of the motion vectors by a block comparison of the reference samples to the current block according to the first search pattern.
