Abstract

The hardware-accelerated real-time compression of 8K Ultra-High-Definition (UHD) video is an exemplary application that empowered by the latest video coding standard. However, the coding tools added to the recently released third-generation audio video coding standard (AVS3) greatly increase the coding complexity, which seriously hinders the efficient implementation of hardware encoder. In order to break the known bottleneck, this paper presents the first open source software library for 8K UHD video coding hardware implementation, namely OpenHardwareVC. Specifically, based on the analysis of the original AVS3 software algorithm, we provide the hardware acceleration designs of the four major coding stages, including coding unit (CU) partition, intra prediction, transform and entropy coding, in this library. Simulation results on Xilinx VU440 FPGA show that the real-time compression of 8K UHD videos at 30 frames per second (fps) can be easily supported based on software-described modules packaged in this library. The release of this library is quite favorable for the hardware design and system implementation of UHD video coding, which is also beneficial to the promotion of the new coding standard. The open source library for OpenHardwareVC is available at https://git.openi.org.cn/OpenHardwareVC.
