Please HELP!!!

hello! i m making my project on implementation of DCT using VHDL. In this i have done my coding in structural modeling for Data sequence up to N=16 point DCT. But my whole coding is in real. i.e. real I/P, real computation and real O/P. due to this problem my code is not synthesizable as I/p and O/p both shuld be in binary form....so, can any 1 suggest me what 2 do, to make my Whole program synthesizable without taking much time as i m left with only 2 weeks for my final project completion!!!! PLease HELP!!!!
 

Hello,

You can do one of the following:

1- Use a softcore processor such as microblaze, which has single precision floating ponit unit. However, this solution needs sometimes if you didn't use this method before.

2- Use only the following library for math
Code: 
library IEEE;
library IEEE.numeric_std.all;
Then, you need a type conversion function such as "to_integer", and deal with your vectors as "signed or unsigned"

regards,
