High-Throughput HEVC Intrapicture Prediction Hardware Design Targeting UHD 8K Videos

This paper presents a high-throughput hardware architecture for the HEVC intrapicture prediction targeting the processing of UHD 8K (7680x4320 pixels) videos at 120 frames per second. The proposed design supports all intra prediction modes and all block sizes. It implements an internal mode decision algorithm that is more hardware friendly than RMD at the cost of a negligible 0.17% BD-rate impact (intra-only). When synthesized to the NanGate 45nm 0.95v cell library targeting a frequency of 529MHz, the proposed design used 4952K gates and showed a power dissipation and an energy efficiency of 363mW and 32.02pJ/sample respectively.
