library IEEE;
use IEEE.STD_LOGIC_1164.all;

entity Gray_to_Binary is
     port(
         din : in STD_LOGIC_VECTOR(3 downto 0);
         dout : out STD_LOGIC_VECTOR(3 downto 0)
         );
end Gray_to_Binary;

architecture Gray_to_Binary_arc of Gray_to_Binary is
begin

    dout(3) <= din(3);
    dout(2) <= din(3) xor din(2);
    dout(1) <= din(3) xor din(2) xor din(1);
    dout(0) <= din(3) xor din(2) xor din(1) xor din(0);

end Gray_to_Binary_arc;
