A VVC Fractional Interpolation Hardware Using Memory Based Constant Multiplication
Hossein Mahdavi, İlker Hamzaoğlu · 2021
In this paper, a novel versatile video coding (VVC) fractional interpolation (FI) hardware using memory based constant multiplication is proposed. The proposed hardware stores pre-computed products of an input pixel with multiple constant coefficients in memory. It implements multiplications with constant coefficients using these pre-computed products. Several optimizations are proposed to reduce memory size. The proposed VVC FI hardware can process 49 full HD (1920×1080) video frames per second. It has up to 9.4% less power consumption than VVC FI hardware in the literature.
