How to implement exponential in IP core in xilinx? I tried using sing and cosh and then a adder but the output is not satisfactory.

Did you want to write 'singing' or 'sing-a-song'? I can tell you: This won't help! Been there, done that hundreds of times... For your 'cosh' problem I would suggest http://forums.xilinx.com/ These guys are very supportive and will be more than happy to solve your problem
I think he wants to emulate this with sin hyperbolicus / cos hyperbolicus, but this is not necessary. One would use the CORDIC anyway to calculate this, and CORDIC gives you the EXP directly. Just read the manual.
I meant sinh sorry for the mistake
Yes you are right but CORDIC is not giving me direct exponential. I did go through the manual. What i figured out is as e^x = sinh + cosh so we can generate sinh and cosh using CORDIC and then use a adder to get the answer. But the result does not come correct.
