An Approximate Versatile Video Coding Fractional Interpolation Hardware

2020    Azgin, Hasan; Kalali, Ercan; Hamzaoglu, Dicer

In this paper, approximate Versatile Video Coding (VVC) fractional interpolation filters are proposed. They significantly reduce computational complexity of VVC fractional interpolation with a negligible PSNR loss and bit rate increase. In this paper, an approximate VVC fractional interpolation hardware implementing the proposed approximate filters is designed and implemented. The proposed approximate hardware has less area and up to 40% less power consumption than exact VVC fractional interpolation hardware. Therefore, it can be used in consumer electronics products that require low power VVC encoder hardware.
