Development of SyReC based expandable reversible logic circuits
Reversible computing is gaining high interest from researchers due to its
various promises. One of the prominent advantages perceived from reversible
logic is that of reduced power dissipation with many reversible gates at hand,
designing a reversible circuit (combinational) has received due attention and
achievement. A proposed language for description of reversible circuit, namely
SyReC, is also in place. What remain are the software tools which would help in
reversible circuit synthesis through simulation. Beginning with the smallest
reversible circuit realizations the SyReC statements and expressions, we employ
a hierarchal approach to develop a complete reversible circuit, entirely from
its SyReC code. We implement this as a software tool. The tool allows a user to
expand a reversible circuit of choice in terms of bit width of its inputs. The
background approach of expansion of a reversible circuit has also been proposed
as a part of this dissertation. Also, a user can use the tool to observe the
effect of expansion on incurred costs, in terms of increase in number of lines,
number of gates and quantum cost. The importance of observing the change in
costs with respect to scale of expansion is important not only from analysis
point of view, but also because the cost depends on the approach used for
expansion. This dissertation also proposes a reversible circuit design for
elevator controller (combinational) and the related costs. The aim is to
emphasize use of the proposed approach is designing customized circuits.Comment: arXiv admin note: text overlap with arXiv:1110.2574 by other author
