special functions for DSP in FPGA implementation

I used to implement some complicated DSP algorithms in TI DSP chips. Now, we are trying to do the implementation in FPGA. Does Altera FPGA already have a library for modules such as ln(x), cos(x), at...

Does Altera FPGA already have a library for modules such as ln(x), cos(x), atan(x), sqrt(x), and 1/x etc?

See http://www.altera.com/literature/ug/ug_altfp_mfug.pdf for a list of floating point operations you get "for free". Probably most of what you're looking for (a subset from <math.h>) is available.

But as Dave, Tricky mentioned: floating vs. fixed, LUT vs. logic - there's different ways you can do it, but the above is what you can get "for free".

Good luck.
