ARCHITECTURE FOR REAL-TIME IMAGE CODING
K. Dezhgosha · 1990
Digital image coding using vector quantization (VQ) based techniques provides low-bit rates and high quality coded images, at the expense of intensive computational demands. The computational requirement, which is due to the encoding search process, has hindered application of VQ to real-time high-quality coding of color TV images. Reduction of the encoding search complexity through partitioning of a large codebook into on-chip memories of a concurrent VLSI chip set is proposed in this paper. The architecture is capable of real-time processing of 480x768 pixels per frame with refreshing rate of 30 framedsecond. A floorplan for the CDC chip has been developed.
