用Verilog 实现将比特流数据转化为SPI协议数据的适配器

library verilog;
use verilog.vl_types.all;
entity EndFlagDecision is
    generic(
        S_WaitforCMPResValid: integer := 1;
        S_DotheComparation: integer := 2;
        S_IDLE          : integer := 4;
        TAILFLAG        : integer := 441
    );
    port(
        Clock50MHz      : in     vl_logic;
        RST             : in     vl_logic;
        SampleCLK       : in     vl_logic;
        DatafromSRC     : in     vl_logic_vector(31 downto 0);
        EndFlag         : out    vl_logic
    );
end EndFlagDecision;
