A CORDIC like processor for computation of arctangent and absolute magnitude of a vector

Abstract

In this paper, we propose a CoOrdinate Rotation DIgital Computer (CORDIC) like processor for computing absolute magnitude of a vector and its corresponding phase angle. It does not require the scale factor compensation step and addition/subtraction operation along the z datapath, has a convergence range over the entire coordinate space and shows similar error characteristics as that of the conventional CORDIC. The synthesis result shows that the proposed processor is hardware economic and suitable for low power applications.
