MASK解调的VHDL代码

Question

当MASK中M等于四时，MASK解调的VHDL代码。

Answer 1

以下代码仅供参考：

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

entity MaskDemodulator is
    Port ( CLK : in STD_LOGIC;
           RESET : in STD_LOGIC;
           DATA_IN : in STD_LOGIC_VECTOR(7 downto 0);
           MASK : in STD_LOGIC_VECTOR(7 downto 0);
           DEMOD_OUT : out STD_LOGIC);
end MaskDemodulator;

architecture Behavioral of MaskDemodulator is
begin
    process(CLK, RESET)
    begin
        if RESET = '1' then
            DEMOD_OUT <= '0';
        elsif rising_edge(CLK) then
            if DATA_IN = MASK then
                DEMOD_OUT <= '1';
            else
                DEMOD_OUT <= '0';
            end if;
        end if;
    end process;
end Behavioral;
