The authors describe an LSI that was developed for wide application in digital video signal processing. The LSI consists of two independent 12-bit full adder/subtracters and a variable delay unit. The minimum arithmetic operation cycle time is 67 ns and the power dissipation is 250 mW. The LSI is packaged in a 135-pin RIT package. It has a rather simple structure, but has very powerful applications in real-time video signal processing. The application of this LSI to a TV conferencing codec is presented.
