| Abstract: | This paper presents two kinds of algorithm for conversion between BCD code and binary code. Both binary-to-BCD and BCD-to-binary conversion are implemented by a unified circuit. Only the shift operation and add computation are needed when converting. Finally we compare their speed and overhead with each other and other algorithms. |
