This paper presents a high throughput architecture for a Motion Compensation (MC) sample interpolator targeting the High Efficiency Video Coding (HEVC) standard. Real-time operation and low power dissipation in video coding systems have become important research challenges, especially in mobile devices with limited computational resources and battery availability. The Fractional Motion Estimation (FME) is one of the tools in the interframe prediction module, which has the goal of reducing temporal redundancies by capturing motion more accurately. The Motion Compensation, responsible for compensating the motion detected at the FME process, demands the major computational effort at the decoder side and represents one of the main challenges when developing real-time HEVC decoders. The proposed architecture is able to save hardware resources through an optimized filter organization and is capable to decode UHD [email protected] video sequences in real time when synthesized for the TSMC 65nm standard-cell library.
