    Abstract

    This paper presents a motion compensation (MC) architecture for 8K UHDTV HEVC video decoder. UHDTV's high resolution significantly increases throughput and memory traffic. Moreover, HEVC supports new coding tools like various sizes of coding unit ranging from 8 to 64. To solve these problems, we propose three optimization schemes. Firstly, four-bank parallel 2D cache organization is proposed to reduce 61.86% memory traffic and support higher interpolator throughput for HEVC. Secondly, we propose pipelined Write-Through mechanism (WTM) to achieve conflict-free performance. Moreover, WTM scheme contributes to around 50% reduction on both memory area and logic gate. Finally, highly parallel interpolator with proposed cache forms integral structure supporting UHDTV. In 90nm process, our design cost 103.6k logic gates with 12kB cache memory. The proposed architecture can support real-time decoding 7680×4320@30fps at 280MHz.
