Dmitry, could you please explain how to apply CORDIC to exponential
function?

I just recently started to learn about that algorithm and how to use
it for magnitude, phase, sine and cosine calculations. But I would
like  to  learn  how to use CORDIC for other elementary math. Not much
pointers on the net :(

BTW, it doesn't look so good for magnitude calculation. It takes
around 1500 cycles for PIC to find sqrt(x^2+y^2), where x, y are 16
bit signed numbers. Probably, using good square and square root
routines would be faster in that case.

Thanks in advance,

 Nikolai

P.S. Good starting point to get into CORDIC:
