In this paper we present a new CORDIC algorithm for the vectoring mode, based on the use of radix-4 preserving a complexity in the microrotations that is similar to that of the conventional radix-2 CORDIC. The use of this radix, together with the inclusion in the CORDIC algorithm of the zero skipping technique, reduces by more than half the number of iterations with respect to the conventional radix 2 CORDIC, with the consequent reduction of time in recursive architectures or area in pipelined architectures. In processes such as SVD or matrix triangularization in which the evaluation of the rotation angle is required, this algorithm is shown to be specially efficient.
