| Abstract: | Reversible logic is a new research area that has developed rapidly in recent years.It has received great attention in all aspects due to their ability to reduce the power dissipation.This paper proposes a new re-versible logic gate—NC gate.This gate can independently complete Binary Coded Decimal（BCD）adder over-flow detection logic.Meanwhile,with 4×4 reversible adder circuits—ZS gate which was designed by the au-thor,a new reversible BCD adder is designed in this paper.The proposed reversible BCD adder is optimized in terms of number of reversible gates and garbage outputs compared to the previous counterparts. |
