“…The most existing reversible decoders (Majumder et al, 2015c;Mamun et al, 2013;Misra et al, 2014;Shamsujjoha and Babu, 2013;Sharma et al, 2014;Sharmin et al, 2011) do not use efficient circuits. The proposed decoder block, called GH-DEC, uses the NOT, AND, OR operations to decrease the number of constant inputs, number of garbage outputs, quantum cost, and circuit complexity.…”

Reversible circuit design can be applied in various emerging technologies such as quantum computing. Since researchers have proposed many building blocks and designed small circuits (e.g., reversible full adder) already, it is the time to design large-scale reversible circuits. This paper proposes a novel quantum reversible 32-bit MIPS register file for quantum computer processors. It presents a reversible 5-to-32 decoder, 32 reversible buffer registers, and two reversible 32-to-1 multiplexers, too. The proposed reversible decoder block, namely GH-DEC, and the proposed reversible multiplexer block, namely GH-MUX, use the Feynman, Toffoli, and Fredkin gates. They have been designed by a minimum number of constant inputs, number of garbage outputs, and quantum cost. Besides, output expressions of all the circuits are simplified to enhance the performance of proposed quantum design, considerably. Comparison results show that the proposed reversible design surpasses the existing works in terms of the number of constant inputs, number of garbage outputs, and quantum cost.
