摘要

本文介绍了文献中第一个针对AOM Video 1 (AV1)视频格式的双自导滤波器(DSGF)的专用硬件设计。DSGF是编码循环中的最后一个滤波器，用于减弱模糊伪影，提高主观视频质量。所提出的硬件设计以AV1解码器为目标，它能够在212.86 MHz运行时以每秒60帧的速度处理每帧3840 × 2160美元像素的超高清(UHD)视频。该架构使用40 nm TSMC库合成为标准单元，使用177.58 kgates，功耗为120.21mW。

An UHD 4K@60fps Dual Self-Guided Filter Targeting the AV1 Decoder

This paper presents the first dedicated hardware design in the literature for the Dual Self-Guided Filter (DSGF) from the AOM Video 1 (AV1) video format. The DSGF is one of the last filters in the encoding loop and is used to attenuate blurring artifacts and to improve the subjective video quality. The presented hardware design targets the AV1 decoder and it is able to process Ultra-High Definition (UHD) videos with $3840\times 2160$ pixels per frame at 60 frames per second when running at 212.86 MHz. The architecture was synthesized to standard cells using the 40 nm TSMC library, using 177.58 kgates and with a power dissipation of 120.21mW.
