High quality, low memory bandwidth motion estimation processor

摘要

An apparatus for motion estimation generally including a memory and a circuit. The circuit may be configured to (i) search for a first motion vector for a first current block among a plurality of first reference samples, (ii) copy a plurality of second reference samples from the memory and (iii) search for a second motion vector for a second current block among the second reference samples copied from the memory and at least a portion of the first reference samples.
