Abstract :
This paper describes a 95mW MPEG2 MP@HL motion estimation processor core for portable and high resolution video application like an HD camcorder. It features a novel hierarchical algorithm and a low power ring-connected systolic array architecture. It supports the frame/field and bi-directional prediction with half-pel precision for 1920×1080@30fps resolution video. The search range is ±128×±64. The ME core integrates 2.25M transistors in 3.1mm×3.1mm using 0.18micron technology.
