[sdiy] CORDIC

[James Patchell]

Well, I am hoping somebody on this list can give me some help.  I am 
looking for information on the CORDIC algorithm.  That stands for 
Coordinate Rotation Digital Computer.  At first blush, this may seem to 
have very little to do with Synth-DIY, but this algorithm can be used to 
generate transcendental functions using only shifts and adds very quickly 
(sin, cos, atan, hyperbolic functions, square roots...etc), and can be 
easily implemented in FPGA's, as well as simple micros, such as the AVR.  I 
am looking into applications for digital synths, as well as other 
things...so, if anybody knows of any good links with information, please 
let me know...here are a couple of good ones I have found...
