Abstract
A 4K and Main-10 HEVC video decoder LSI is fabricated in a 28nm CMOS process. It adopts a block-concealed processor (BcP) to improve the visual quality and a bandwidth-suppressed processor (BsP) is newly designed to reduce 30% and 45% of external data accesses in playback and gaming scenario, respectively. It features fully core scalable (FCS) architecture which lowers the required working frequency by 65%. A 10-bit compact scheme is proposed to reduce the frame buffer space by 37.5%. Moreover, a multi-standard architecture reduces are by 28%. It achieves 530Mpixels/s throughput which is two times larger than the state-of-the-art HEVC design [2] and consumes 0.2nJ/pixel energy efficiency, enabling real-time 4K video playback in Ultra-HD Blu-ray player and TV systems.
