This work proposes a hardware architecture for fractional-pixel interpolation filter defined in the royalty-free AV1 video coding standard. Analysis conducted in this work shows that the AV1 Regular family of filters has the highest usage especially when considering high resolution videos. The proposed architecture implements the 15 interpolation filters of the AV1 Regular family and is capable to interpolate videos of up to 8K video resolution at 120 fps. The proposed architecture achieves the highest throughput compared to related works.
