here you go - a 16 bit multiplier module: 


library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
entity mult_16 is
port (
  a,b : in  unsigned(15 downto 0);
  c   : out unsigned(31 downto 0)
);
end entity mult_16
architecture rtl of mult_16 is
begin
  c <= a * b;
  
end architecture rtl;
