Sigma DSPs able to do exponents of signals
I am completely new to ADI's line of Sigma DSPs. I wonder if they can calculate exponents of signals so that doing polynomial fits would be possible. For example, sig + k1*sig^2 + k2*sig^3 ...
From reading the datasheet I suspect they cannot, but often datasheets are not exhaustive.
Thanks to anyone with advice!
Hello EEguy,
The datasheet tells you the ins and outs, but the best place to see what SigmaDSP can do is the SigmaStudio wiki: https://wiki.analog.com/resources/tools-software/sigmastudio
Yes you certainly can make a power series function with SigmaDSP, and it's quite easy. The schematic shown below implements the first five terms of the Taylor series for y = e^x:
As the input (x) ramps up, the output increases exponentially:

A big thanks, Bob!
