andarith.vhd

实现了VHDL乘法器

entity andarith is port(
   abin : in std_logic;
    din : in std_logic_vector(7 downto 0);
   dout : out std_logic_vector(7 downto 0));
end andarith;
architecture behav of andarith is
begin
   process(abin,din)
   begin
      for i in 0 to 7 loop
         dout(i) <=din(i) and abin;
      end loop;
