Honored Contributorspecial 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...

Honored ContributorThe answer is not really, but they are easy to, but the way you speak sounds like you have little knowledge of how fpgas work. Nothing is "called", you instantiate modules and implement them on the chip.
Things like ln and sin, COs etc would usually be done with a look up table. The values can easy be calculated in hdl itself at elaboration time before the design is synthesised onto the chip. Model sim just stimulated the hardware description.
