Re: Cordic

Bryan,
 
The CORDIC core can rotate a unit vector by input angle theta to produce an output vector sin(theta), cos(theta). This is described in more detail in this core's datasheet.
 
Are you simply trying to produce sin/cos waveforms? If that is the case, I would recommend you take a look at the Sine-Consine Look-up Table (Digital Signal Processing -> Trig Functions) or DDS Compiler/Direct Digital Synthesizer (Digital Signal Processing -> Waveform Synthesis) cores.
 
Cheers,
bt
