Abstract :
In this paper the hardware friendly Multi Point Diamond Search (MPDS) motion estimation (ME) algorithm is evaluated in the High Efficiency Video Coding Standard (HEVC). The MPDS algorithm was implemented in HEVC reference software and its efficiency is compared with the standard HEVC fast algorithm, the Enhanced Predictive Zonal Search (EPZS). The evaluation result, in average, shows loses of only 1.7% in the compression rate and 0.05% in PSNR. However, the main advantage of the MPDS algorithm is its hardware friendly aspect and this paper also presents its hardware design focused on real time processing HD 1080p videos. The designed architecture is capable to process HD 1080p videos in real time when synthesized for TSCM 90nm technology. The MPDS algorithm has obtained a good tradeoff among quality, compression rate and costs for its hardware implementation.
