..................CORDIC DDS FPGA GPL core.............


In "expanded" form this is:

COordinate Rotation DIgital Computer - Direct Digital Synthesis - Field
Programmable Gate Array - GNU Public License - core

;-)


Seriously...

As I didn't know until now what a CORDIC was and searched the Email archives
at hpsdr.com, but didn't find an explanation of it, I searched the internet
and found a nice one at:

Cool!!!

I now at least have some understanding of the hardware advantages of using
this technique.
The Algebra I have to study some more though..... :-/
