Abstract :
Sub-pixel interpolation is one of the most computationally intensive parts of High Efficiency Video Coding (HEVC) video encoder and decoder. Therefore, in this paper, a reconfigurable HEVC sub-pixel (half-pixel and quarter-pixel) interpolation hardware for all prediction unit sizes is proposed. The proposed reconfigurability reduces the area and power consumption of HEVC sub-pixel interpolation hardware more than 30%. The proposed hardware, in the worst case, can process 64 quad full HD (2560×1600) video frames per second.
