Solution

library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.NUMERIC_STD.ALL;

entity Multiplier is
   port
   (
      m, q: in std_logic_vector(3 downto 0);

      p: out std_logic_vector(7 downto 0)
   );
end entity Multiplier;

architecture Behavioral of Multiplier is
begin

   p <= std_logic_vector(unsigned(m) * unsigned(q));

end architecture Behavioral;
