Abstract

A parallel vector quantization (VQ) processor has been developed aiming at real-time compression of motion pictures using 0.35um CMOS technology. The chip employs a new simple search algorithm for VQ encoding. As a result, the die area of the chip is decreased to 33% of that of conventional fully parallel design. This chip can handle 2048 template vectors by a single chip and is applicable to real-time compression of 30 frames/see full-color VGA (640x480 pixels) images. The chip operates at 33 MHz with power dissipation of 790mW under 2.5V power supply.
