Counting sequences have many applications in logic-circuits. Sometimes it is desirable to have a counting sequence such that the number of bit changes from one codeword to its successor is as large as possible. In any number base there is a plurality of ways that numbers can be encoded. One of the ways for encoding binary is called Gray Code (also known as reflected binary code). An n-bit Gray code is a circular listing of the 2n n-bit strings so that successive strings differ only in one bit position. Gray sequence is a counter sequence where the Hamming distance between successive states is one. There are different types of gray code sequences: Binary reflected, Uniformly balanced, Antipodal, Maximum Crossover Hamming Distance, Maximum Gap and Non Composite to name a few. On the other hand Reversible logic has received great attention due to their ability to reduce the power dissipation--an important aspect of low power circuit design. This paper proposes the design of various gray code counters using reversible logic gates and compares their performance.
