Abstract :
A technique to eliminate redundant distance calculations is used in a vector quantization (VQ) processor which handles 2048 template vectors with a single chip. A real-time motion picture compression system employing this chip can transmit five QVGA (320/spl times/240 pixels) images per second at <64 kb/s.
