How to design acos, atan, and a division blocks in Dsp Builder

Hi, I have big problems in my design. So I NEED YOUR HELP. Have you ever had in Dsp Builder to design some block as - Arccos (y =acos(x)) - Atan (y=atan(x)) - Divider blocks? (y/x). There i...

Hi!

I have had encouraging results using LUTs for implementing Acos and asin function in Dsp Builder. I'm still using DSP Builder 6.0 on Matlab/Simulink 7.0.1 without problem.

How to find the divider block suitable for me. The one which for an n-bits signed-fractional numerator and an m-bits signed-fractional denomintor could gives me a direct signed-fractional result.

Could you tell me more about the standard (parallel) megafunction. Is it the one we have in Altera Dsp Builder library which computes the quotient and the remaninder? Is It the so called lpm divider megafunction?

I've even installed the CD with megacore functions. Any divider block available.

Hope to year from you soon.
