摘要

Major content providers such as YouTube and Netflix use AV1, a state-of-art video coding standard that was finalized in 2018. This paper presents a video processor that supports the AV1 standard via a Multi-Format video Decoder (MFD). An MFD can decode various video coding standards, such as H.264/AVC, HEVC and AV1. The video decoder can decode up to 8K Ultra HD (8K-UHD) video at 30fps at 468MHz core clock frequency. The MFD is fabricated using a state-of-the-art 5nm CMOS process with a 5,835k NAND2 equivalent gate count and 518kB SRAM. For AV1, MFD dissipates 116mW for decoding AV1 $7680 imes4320p$ video at 30fps (0.12nJ/pixel) with core operating voltage at 0.7V.
