A CORDIC like processor for computation of arctangent and absolute magnitude of a vector
A CORDIC like processor for computation of arctangent and absolute magnitude of a vector
In this paper, we propose a CORDIC like algorithm for computing absolute magnitude of a vector and its corresponding phase angle. It eliminates scale factor compensation step as well as the addition/subtraction operation along the z datapath. The synthesis result shows that the proposed processor is hardware economic and suitable for low power applications.

Abstract
In this paper, we propose a CORDIC like algorithm for computing absolute magnitude of a vector and its corresponding phase angle. It eliminates scale factor compensation step as well as the addition/subtraction operation along the z datapath. The synthesis result shows that the proposed processor is hardware economic and suitable for low power applications.
