Abstract
A full-precision floating-point Cordic algorithm, suitable for the implementation of a word-serial Cordic architecture, is presented. The extension to existing block floating-point Cordic algorithms is in a floating-point representation for the angle. The angle is represented as a combination of exponent, microrotation bits, and two bits to indicate prerotations over π2 and π radians. Representing floating-point angles in this fashion maintains the accuracy that is present in the input data, which makes it ideally suited for implementing a floating-point Givens operator
