Arctan Function
ATAN_X calculates the inverse tangent of a fraction.
Overview
ATAN_X calculates the inverse tangent of a fraction. It has a fully pipelined architecture and uses fixed-point mathematics throughout. Input values are accepted as 16-bit unsigned fractions in the range 0 to 1. Output values are 16-bit unsigned fractions in the range 0 to π/4. Both input and output values are in [16 16] format with 0 integer bits and 16 fraction bits. As an example the input value 0x4000 would signify the fraction 0.5.
