Reduced Latency Square-Root calculation for Signal Processing using Radix-4 Hyperbolic CORDIC

Abstract

Till now the CORDIC algorithm is primarily used to calculate only trigonometric operations. In the proposed work, we extend the Radix-4 CORDIC algorithm to the hyperbolic vectoring mode to implement fast computation of Square-Root. This paper illustrates the implementation of a regular VLSI architecture for Radix-4 hyperbolic vectoring CORDIC on FPGA platform. The speed can further be increased with higher version of FPGA devices. A comparison between Radix-2 and Radix-4 CORDIC algorithm based on the simulation results is also presented in the work.
