| Popis: | This paper presents a hardware design for the Deblocking Filter (DBF) in the AOM Video 1 (AV1) decoder. The DBF is the first filter of the AV1 encoding loop, being used to attenuate blocking artifacts and to improve the subjective video quality. The presented hardware design is capable to process up to 56 samples per clock cycle, aiming at processing Ultra-High Definition (UHD) videos with 4098×2160 pixels (4K) at 60 frames per second when running at 16.2 MHz. The architecture was synthesized to ASIC using the 40nm TSMC library, requiring 39.35K gates and with a power dissipation of 3.96 mW. At the best of the authors' knowledge, this is the first hardware design targeting the AV1 DBF presented in the literature. |
