Look Up Table for sin/cosin functions NEEDED!

[night_bird]

Hi!

I'm begining to implement a system on FPGA and
I am supposed to generate 'I' and 'Q' components for and input signal. So I have to generate sin/cosine function and I know that I can do it by using a LUT but I don't know how to implement it in VHDL code...To continue with the project and learn more I need it, someone could tell me how to do it or send me a code example??


I need help...
Thanks in advance!!!
