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.
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.
