Chrominance/luminance signal separation and syntheses chips developed with a DSP silicon compiler

VLSI chips for luminance/chrominance (Y/C) signal separation and synthesis have been developed. Application-specific FIR filter structures and canonical signed-digit representation (CSR) multipliers used in the filters make it possible to develop compact high-speed VLSI chips. A silicon compiler, which employs the optimal FIR filter structures and supplies the optimal filter design faculty, has contributed to quick VLSI development. Y/C signal separation using four video FIR filters and Y/C signal synthesis using three video FIR filters are implemented on single chips by 1.2- mu m CMOS technology.>
