该论文提出了一款用于8K超高清应用的4Gpixel/s H.265/HEVC视频解码器芯片，支持8/10bit像素精度。解决了超高清视频解码中的高吞吐量和低复杂度需求，实现了7680×4320分辨率、120fps的实时解码。
Jiayi Zhu, Yijin Zhao, Jinjia Zhou, Shuping Zhang, Shinji Kimura, Takeshi Yoshimura, Satoshi Goto Waseda University, Kitakyushu, Japan 8K Ultra HD is being promoted as the next-generation digital video format. From a communication channel perspective, the latest high-efficiency video coding standard (H.265/HEVC) greatly enhances the feasibility of 8K by doubling the compression ratio. Implementation of such codecs is a challenge, owing to ultrahigh throughput requirements and increased complexity per pixel. The former corresponds to up to 10b/pixel, 7680×4320pixels/frame and 120fps – 80× larger than 1080p HD. The latter comes from the new features of HEVC relative to its predecessor H.264/AVC. The most challenging of them is the enlarged and highly variable-size coding/prediction/transform units (CU/PU/TU), which significantly increase: 1) the requirement for on-chip memory as pipeline buffers, 2) the
