This paper presents a motion estimation and compensation large scale integration (LSI) for the MPEG2 standard. An embedded RISC processor and special hardware modules enable the LSI to achieve a sufficient ability to perform real-time operation and provide the availability to realize many kinds of block matching algorithms. Using a three-step hierarchical telescopic search algorithm, a single chip accomplishes real-time motion estimation with search ranges of /spl plusmn/32.5/spl times//spl plusmn/32.5 pixels for motion vectors. The chip was fabricated using 0.5-/spl mu/m CMOS technology and has an area of 16.5/spl times/16.5 mm/sup 2/ and 2.0 M transistors.
