VHDL Code

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;

entity gray2binary is
    Port ( g : in STD_LOGIC_VECTOR (3 downto 0);
           b : out STD_LOGIC_VECTOR (3 downto 0));
end gray2binary;

architecture Behavioral of gray2binary is
begin
    b(3)<= g(3);
    b(2)<= g(3) xor g(2);
    b(1)<= g(3) xor g(2) xor g(1);
    b(0)<= g(3) xor g(2) xor g(1) xor g(0);
end behavioral;
