I did some experimentation with it early on, before we gave up on our optical carpet tracking scheme.

My thought is that the CORDIC implementation you're using is no good for our application. I'm wondering if the one you're using uses floating point math. If it does, that would swell the code due to the fact that the math library would have to emulate the floating point operations in software.
CORDIC was devised specifically to avoid floating point operations. It uses addition, subtraction, and bitwise shifts. Doing those with floating point would be, um, pointless.
