CORDIC(Coordinate Rotation Digital Computer)

Hello, everyone.

I'm a student in Korea, and I wonder CORDIC algorithm for verilog HDL.

I have found CORDIC verilog code..

but, i cant find that code.

I need a CORDIC code. Because of, I'd like to make angle detection code, 
so need CORDIC code for angle detection.

If you know that mothod or any information, tell me please.

Thank you, everyone...

Best regards.
