Floating Point and Fixed Point.

I wrote an example myself as below. I think it is the correct way to do a summation for floating point values. Am I right?

Library ieee;

use ieee.std_logic_1164.all;

use ieee.std_logic_arith.all;

use ieee.std_logic_unsigned.all;

Library altera_mf;

use altera_mf.altera_mf_components.all;

entity floatadd is

port(

inA,inB : in std_logic_vector(31 downto 0);

inclk : in std_logic;

out1 : out std_logic_vector(31 downto 0)

);

end floatadd;

architecture add of floatadd is

component altfp_add_sub

generic (

direction : string := "ADD";

pipeline : natural := 11;

rounding : string := "TO_NEAREST";

width_exp : natural := 8;

width_man : natural := 23

);

port(

clock : in std_logic;

dataa : in std_logic_vector(width_exp+width_man+1-1 downto 0);

datab : in std_logic_vector(width_exp+width_man+1-1 downto 0);

result : out std_logic_vector(width_exp+width_man+1-1 downto 0)

);

end component;

begin

G1: altfp_add_sub

port map (inclk,inA,inB,out1);

end add;
