quartus 设计设计操作模块，实现对计算模块的控制和调度，例如选择计算模块、输入输出控制等。的vhdl代码

以下是一个简单的 VHDL 代码示例，用于控制和调度计算模块：

library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;

entity ControlModule is
    port (
        clk : in std_logic;
        reset : in std_logic;
        select_input : in std_logic_vector(1 downto 0);
        start : in std_logic;
        done : out std_logic;
        input_data : in std_logic_vector(7 downto 0);
        output_data : out std_logic_vector(15 downto 0)
    );
end entity ControlModule;

architecture Behavioral of ControlModule is

    -- Define states for the state machine
    type state_type is (IDLE, SELECT, CALCULATE, OUTPUT);
    signal state : state_type := IDLE;

    -- Define signals to store input and output data
    signal input_data_reg : std_logic_vector(7 downto 0);
    signal output_data_reg : std_logic_vector(15 downto 0);

    -- Define constants for module selection
    constant MODULE_1 : std_logic_vector(1 downto 0) := "00";
    constant MODULE_2 : std_logic_vector(1 downto 0) := "01";
    constant MODULE_3 : std_logic_vector(1 downto 0) := "10";

begin

    -- Input data register
    input_data_reg <= input_data when state = SELECT else input_data_reg;

    -- Output data register
    output_data <= output_data_reg when state = OUTPUT else (others => '0');

    -- State machine process
    process (clk, reset)
    begin
        if reset = '1' then
            state <= IDLE;
        elsif rising_edge(clk) then
            case state is
                when IDLE =>
                    -- Wait for start signal
                    if start = '1' then
                        state <= SELECT;
                    end if;

                when SELECT =>
                    -- Select module based on input
                    case select_input is
                        when MODULE_1 =>
                            state <= CALCULATE;
                        when MODULE_2 =>
                            state <= CALCULATE;
                        when MODULE_3 =>
                            state <= CALCULATE;
                        when others =>
                            state <= IDLE;
                    end case;

                when CALCULATE =>
                    -- Perform calculation based on selected module
                    case select_input is
                        when MODULE_1 =>
                            output_data_reg <= std_logic_vector(unsigned(input_data_reg) * 2);
                        when MODULE_2 =>
                            output_data_reg <= std_logic_vector(unsigned(input_data_reg) + 5);
                        when MODULE_3 =>
                            output_data_reg <= std_logic_vector(unsigned(input_data_reg) - 3);
                        when others =>
                            null;
                    end case;

                    -- Move to output state
                    state <= OUTPUT;

                when OUTPUT =>
                    -- Wait for done signal before returning to idle state
                    if done = '1' then
                        state <= IDLE;
                    end if;

            end case;
        end if;
    end process;

end architecture Behavioral;
