Abstract

A number of new algorithms to make an online CORDIC implementation are introduced. The online CORDIC algorithm takes n+6 clock cycles to compute a CORDIC function. It is estimated that an implementation of the proposed algorithm is six to seven times as fast as the traditional CORDIC approach for Given's rotation, and seven to eight times as fast for SVD computation.
