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 low energy HEVC sub-pixel (half-pixel and quarter-pixel) interpolation hardware, which uses Hcub multiplierless constant multiplication algorithm, is proposed. The proposed HEVC sub-pixel interpolation hardware, in the worst case, can process 30 quad full HD (3840×2160) video frames per second. It has up to 48% less energy consumption than original HEVC sub-pixel interpolation hardware.
