In this paper, approximate Versatile Video Coding (VVC) fractional interpolation (FI) filters are proposed. The proposed approximate VVC FI filters reduce computational complexity of VVC FI at the expense of very small quality loss. In this paper, four VVC FI hardware implementing the proposed approximate VVC FI filters are also proposed. The proposed approximate VVC FI hardware have higher speed, smaller area, and up to 51% lower power consumption than the exact VVC FI hardware. Therefore, they can be used in consumer electronics devices requiring high speed, small area, low power consuming VVC encoder hardware.
