Abstract
This paper proposes novel carry select and carry look-ahead BCD adders using reversible logic. Reversible logic gates are widely known to be compatible with future computing technologies which virtually dissipate zero heat. Adders are fundamental building blocks in many computational units. For this reason, we have simulated several adder circuits using the reversible gates. Among all the other adders, the main virtue of BCD adders is that it allows easy conversion to decimal digits for printing or display and faster decimal calculations. These reversible BCD circuits are basis of the decimal ALU of primitive Quantum CPU. The proposed BCD adders have been simulated in VLSI and static timing report was analyzed.
