Cosine and Sine lookup table in vhdl

no no i did read it.. i think your examples were great but it's just that I'm new and I don't know much about vhdl. I would like to use this code posted by you:

LIBRARY ieee;

USE ieee.std_logic_1164.all;

USE ieee.std_logic_arith.all;

USE ieee.math_real.all;

TYPE ROM IS ARRAY(0 TO 511) OF UNSIGNED(8 DOWNTO 0);

FUNCTION INIT_ROM RETURN ROM IS

VARIABLE romvar: ROM;

begin

--for .. loop

-- romvar() :=

--end loop

return romvar;

end;

CONSTANT rom1: ROM := INIT_ROM;

And from what I understand I have to use some sort of generated values for the for loop. can you please help me, I would really appreciate it.
