Question

我正在尝试在 vhdl 中编写用于将两个 100x100 矩阵相乘的代码

    library IEEE;
    use IEEE.STD_LOGIC_1164.ALL;
    use ieee.numeric_std.all;
    library work;
    use work.mult_100x100_pack.all;


    entity multiplier_main_code is
        Port ( in_matrix1 : in  t_2d_array;
               in_matrix2 : in  t_2d_array;
               out_matrix : inout  t_2d_array);
    end multiplier_main_code;

    architecture Behavioral of multiplier_main_code is

    begin

        process(in_matrix1, in_matrix2)
        begin
             for i in 0 to 99 loop
                  for j in 0 to 99 loop
                      for k in 0 to 99 loop
                       out_matrix(i)(j) <= std_logic_vector(signed(out_matrix(i)(j)) + (signed(in_matrix1(i)(k)) * signed(in_matrix2(k)(j))));

                      end loop;
                 end loop;
          end loop;          

    end Behavioral;

它一次又一次地显示错误说： "behavioral"
的类型为 void "Behavioral"

mult_100X100_pack 包的代码是：

library IEEE;
use IEEE.STD_LOGIC_1164.all;
use ieee.numeric_std.all;

package mult_100x100_pack is

    type t_1d_array is array(integer range 0 to 99)of std_logic_vector(7 downto 0);
    type t_2d_array is array(integer range 0 to 99)of t_1d_array;


end mult_100x100_pack;

拜托，有人可以帮我解决这个错误吗？

Answer 1

修复缩进后，您应该很明显遗漏了什么：

process(in_matrix1, in_matrix2)
begin
  for i in 0 to 99 loop
    for j in 0 to 99 loop
      for k in 0 to 99 loop
        -- Do things
      end loop;
    end loop;
  end loop;
-- Perhaps `end process;` might be appropriate here...

Answer 2

您的 process 需要一个 end process; :

     end loop;   

  end process;          

end Behavioral;

这说明了注意正确缩进代码的好处。如果您所有的 end for 都与相应的 for 对齐，这就很明显了。
