Reversible logic is one of the emerging research areas having its applications in the fields of quantum computing, optical computing, DNA computing, nanotechnology, cryptography and bioinformatics. This paper presents the novel design for code converters such binary to gray, gray to binary, BCD to Excess-3 code and Excess-3 to BCD code using reversible logic. The proposed designs are compared with the existing designs in terms of parameters such as reversible gates, constant inputs, garbage outputs and quantum cost.

 
 

Digital logic circuits deal with digital information which are in binary form known as BIT. The symbols used to denote the BIT are ‘0’ and ‘1’. The sequence of 0’s and 1’s is used to represent the data or information is called as CODE. Different varieties of codes are available such as ASCII, BCD and Gray code. A digital logic circuit which is used to convert information in one form to another form is called code converter. Sometimes it is necessary to convert code from one format to another format while performing the operations in digital processors, controllers, etc.
