This paper presents a high quality H.265/HEVC motion estimation implementation with the cooperation of CPU and GPU. The data dependency from MVP (Motion Vector Predictor) restricts the degree of parallelism on GPU. To overcome the constraint from MVP, we propose to use an estimated MVP on GPU and the accurate MVP to refine the motion vector on CPU. GPU fully utilizes its tremendous parallel computing ability without the restriction from MVP. CPU makes up for the deviation from GPU with a small… CONTINUE READING
