  In the recent era, Reversible computing is a growing field having
applications in nanotechnology, optical information processing, quantum
networks etc. In this paper, the authors show the design of a cost effective
reversible programmable logic array using VHDL. It is simulated on xilinx ISE
8.2i and results are shown. The proposed reversible Programming logic array
called RPLA is designed by MUX gate [10] & Feynman gate for 3- inputs, which is
able to perform any reversible 3- input logic function or Boolean function.
Furthermore the quantized analysis with camparitive finding is shown for the
realized RPLA against the existing one. The result shows improvement in the
quantum cost and total logical caculation in proposed RPLA.
