sqrt?

Hello?
Somebody know how to realized a function SQRT in VHDL?
Thank you!

Did you do a Google search for sqrt vhdl? The first hit looks promising to me, but I don't know your application.

I need a sqrt algorithm for calcule the spectrum of a FFT to implement in a remez algorithm.

Yes I did a google search and I found your first hit very interesting and I think use this for start. Now I search how implement a remez algorithm in my FPGA. I found too few informations on this subject and I don't think it's the beast solution for my problem. At the end I want to realize an adaptativ filter on my FPGA.
