What is CORDIC?
 

cordic rotate

short for COordinate Rotate Digital Computer, very useful algorithm
 

CORDIC is an algorithm that enables estimating the angle of a phasor (i.e. a complex number) from its real and imaginary parts. It operates by rotaing the phasor by a predfined sequence of angles (e.g. 180, 90, 45, 22.5 ...) and after each rotation checking if the phasor has crossed the 0 angle. Based on the the outcome of this test, the predefined angle is added to the estimate of the angle.

Hi !

CORDIC alghorithem is an interactive process to performe elementary arithmetic functions like sin, cos, arctg

You can find some docs here

Good luck, Bart
