Hello, I wanted the relationship between the number of iteration vs LUT table entry. Because i wanted to estimate the arc tan to a accuracy of 1 microradians. In my simulation i found that even if the iteration is around 25 iteration i could not achieve the 1 microradian accuracy.
My LUT i have represented using 32 bit and the two number whos atan is to be obtained is also 32 bit(all fixed point).
Please suggest a solution with regards praveen
