A General Methodology and Reconfigurable Architecture for Calculating A^B-Like Functions in the Complex Field

We propose a general methodology and reconfigurable architecture for computing AB-like functions in the complex field. CORDIC and the parabolic synthesis approximation method help the proposed method to be flexible to adjust the precision and complexity of computation. The proposed architecture is reconfigurable to adapt to different functions. The MATLAB test results show that our calculation method’s average relative error is the order of 6×10-5. The synthesis report under TSMC 28nm CMOS technology shows that the proposed design has an area consumption of 7149.86μm2 at the frequency of 1 GHz and the power consumption is 2.0935 mW.
