High-performance architecture of H.264 integer-pixel motion estimation IP for real-time 1080HD video CODEC

Abstract

We propose a new H.264 integer-pixel motion estimation algorithm and circuit architecture to improve the processing speed. The proposed circuit supports 7 kinds of variable block sizes and generates 41 motion vectors. The implemented IP based on the proposed algorithm and architecture processes 60 image frames per second for 1080HD video at the operating frequency of 45.5MHz.
