Hi,
I have been roped into doing some FPGA work (not my field)
I need to do implement the inverse TAN function
The Machlaren expansion is:
arctan(x) = x - x^3/3 + x^5/5 -x^7/7 + ...
not very practical
CORDAC function are suppose to do all trig calcuations in a digital world with just shifts and adds
anyone had any experience?/
