Abstract :
A half-pel precision MPEG2 motion estimation processor using a 0.5 μm CMOS technology supports all prediction modes in MPEG2 including frame, field and dual-prime prediction, and estimates three vectors concurrently. The multiple processor configuration allows a search range expansion by ±127.5, keeping bus traffic constant. It integrates 850 K transistors in a 13.85 mm×13.55 mm silicon die. The observed maximum operating frequency is 75 MHz. At 40 MHz for NTSC, the peak computational power is 20 GOPS and the power dissipation is 1.9 W
