The Square Root Cordic

Abstract

The CORDIC (Coordinate Rotation Digital Computer) algorithm 1 computes certain functions such as the sine, cosine, and square root of (x squared + y squared) using only additions and bit shifting operations. We have implemented an integer math CORDIC algorithm on a high speed RISC processor. During the course of this work, we identified a convergence problem with the square root of (x squared + y squared) CORDIC. A solution to this problem is presented along with an overview of this algorithm.
