Exponential Function

[Phil Moore]

Hello, <br><br>1.) I was wondering if there was any way that I could perform exponential operations on numbers that are stored in memory! <br>
2.) How do I use Coregen to perform addition and multiplication to numbers stored in memory in the fpga, or should I use Coregen?

Yes. It is easiest if the base is 2. For base 2 (ie. 2^x),
separate off the fractional portion of x, look up the
antilog of the fractional portion from a LUT, and then shift
that by the integer part of x.
