Hello Dears
Does CORDIC calculate arcCos(x)?
what is the best way of implementation of it? (instead of Look-up table)
Thanks in advance

Google says that if I want ready to go vhdl code I have to google more. (read: didnt find it in 30 seconds :p )
 

Thanks mrflibble:))
Google says yes/no, ( yes it possible, No it doesn't implement yet).
I used the Taylor series, but it contains a lot of ADD and Multiplier ( for the specific accuracy I need plenty amount of sentences). and the cordid core at "opencore" doesn't cover this function! so searching for another way.
Thanks
Mostafa
