摘要：
A method of mixed-scaling-rotation CORDIC (MSR-CORDIC) with scaling-free rotational operations is disclosed. An elementary angles set is extended by representing the elementary angles as the arctangent of the division of two single signed-power-of-two terms to an enhanced extended elementary angles set. A combination of elementary angles is found from the enhanced extended elementary angles set such that the residue angle error can be minimized. A MSR-CORDIC operation is used to perform the rotating and scaling transformation simultaneously.
