Abstract :
A VLSI architecture for real-time high-quality coding of color TV images at a fixed bit rate of 1.12 BPP is developed. The architecture exploits pipeline/parallel processing an don-chip memory to partition a large codebook into smaller on-chip subcodebooks. The architecture is capable of real-time processing of 480×768 pixels per frame with a refreshing rate of 30 frames/s. A floorplan for the CDC chip is developed
