decoder.vhd

很实用的一个分频带码

library ieee;
use ieee.std_logic_1164.all;
entity decoder is
	port(bin : in std_logic_vector(2 downto 0);
		 de : out std_logic_vector(6 downto 0));
end entity;
----------------------------------------------------
architecture deco of decoder is
	begin
	process(bin)
	begin
	case bin is
		when "000" => de <= "0111111";---0
		when "001" => de <= "0000110";---1
