CALL US: +34 667 249 415    ZIPcores - Fixed-point Mathematics - 4-Quadrant Arctan Function 4-Quadrant Arctan Function   General Description Function y = atan2(y,x) calculates the 4-quadrant inverse tangent in the range -Pi to Pi. Functionally equivalent to the atan2 function in 'C' and MATLAB®. Ideal for the measurement of complex phase in DSP applications. Accuracy to within 0.00008 radians. Key Design Features - Function y = atan2(y,x) - Inputs as 12-bit signed - Output as 19-bit signed - Output range between -Pi and Pi radians - Accurate to within 0.00008 radians - Small implementation size - High-speed fully pipelined architecture - 7 clock-cycle latency Applications - Fixed-point mathematics - Digital Phase-locked Loops (PLLs) - Phase measurements in DSP and digital comms - Cheaper than a CORDIC solution of similar spec.
