Fractional interpolation in Versatile Video Coding (VVC) standard has much higher computational complexity than fractional interpolation in previous video compression standards. In this paper, a low power VVC fractional interpolation hardware is designed and implemented using Verilog HDL. The proposed hardware is the first VVC fractional interpolation hardware in the literature. It interpolates necessary fractional pixels for 1/16 pixel accuracy for all prediction unit sizes. The proposed VVC fractional interpolation hardware, in the worst case, can process 40 full HD (1920x1080) frames per second. It has up to 17% less power consumption than original VVC fractional interpolation hardware.
