Binary to Gray Conversion VHDL source code

This page of VHDL source code covers Binary to Gray Conversion vhdl code.

VHDL Code

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;

entity BinarytoGray is
port( b: in std_logic_vector(3 downto 0); --binary
g: out std_logic_vector(3 downto 0)); --gray
end BinarytoGray;

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