Design of BCD to Excess-3 code converter circuit with optimized quantum cost, garbage output and constant input using reversible gate

摘要

In this paper, we have proposed the optimized BCD to Excess-3 code converter using reversible logic gate. BCD to Excess-3 code can be generated by adding "0011" to BCD number, but in the proposed work, addition is not required. The proposed reversible circuit can be designed using peres gate, Feynman gate and NOT gate optimized quantum cost, garbage output and constant input. The quantum cost (QC), garbage output and constant input of proposed reversible BCD to Excess-3 code converter are respectively 14, 1 and 1 which is better with respect to previously reported results. The improvement is, respectively 0-65%, 66.66-91.66% and 66.66-87.5%.
