General Description

Function y = atan(x) calculates the inverse tangent of a fraction. It has a high-speed, fully pipelined architecture and uses a polynomial with dynamic coefficients to calculate the result to within 0.00004 radians. Input and output values are 16-bit unsigned fractions.

Applications

– Fixed-point mathematics
– Phase measurements in digital communications
– Alternative to using a 64k x 16-bit LUT
– Cheaper than a CORDIC solution
