Abstract
The block-matching motion estimation is the most popular method for motion-compensated coding of image sequence. A VLSI architecture for implementing a full-search block-matching algorithm is presented. Based on a systolic array processor and shift register arrays with programmable length, the proposed architecture has the following advantages: it allows serial data input to save the pin counts but performs parallel processing; it is flexible in adaptation to the dimensional change of the search area via simple control; it can operate in real time for videoconference applications; and it is simple and modular in design, and thus is suitable for VLSI implementation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
