Abstract

The compensation of scale factor imposes significant computation overhead on the CORDIC algorithm. In this paper we present two algorithms and the corresponding architectures (one for both rotation and vectoring modes and the other only for rotation mode) to perform the scaling factor compensation in parallel with the classical CORDIC iterations. With these methods, the scale factor compensation overhead is reduced to a couple of iterations for any word length. The architectures presented have been optimized for conventional and redundant arithmetic.
