ABSTRACT:
An apparatus generally having a first circuit and a second circuit is disclosed. The first circuit may be configured to (i) copy a plurality of first reference samples of a first reference image from an external memory, the first reference samples being proximate a first position within the first reference image and (ii) generate a first motion vector corresponding to a first current block of a current image by searching among the first reference samples. The second circuit may be configured to (i) copy a plurality of second reference samples of the first reference image from the external memory, the second reference samples being (a) proximate a second position within the first reference image and (b) non-adjacent the first reference samples and (ii) generate a second motion vector corresponding to the first current block by searching among the second reference samples.
