Re: Cordic o solution

The obvious way is to have a lookup table where the number of points taken for your sin/cosine wave should satisfy the nyquist requirement. It probably depends on your application, but if you want to be able to control the output frequency and phase dynamically you can have a look at the DDS core. http://www.xilinx.com/products/ipcenter/DDS_Compiler.htm

If can find lots of info on this type of stuff on google by search for "direct digital synthesizer".

Cheers
Jaco
