Abstract:
Various embodiments of the present invention provide pipelined vectoring-mode CORDICS including a coordinate converter operable to yield a converted vector based on an input vector, wherein an x coordinate value of the converted vector is positive, a y coordinate value of the converted vector is positive, and the x coordinate value is greater than or equal to the y coordinate value, a pipeline of vector rotators operable to perform a series of successive rotations of the converted vector to yield a rotated vector and to store rotation directions of the series of successive rotations, and at least one lookup table operable to yield an angle of rotation based on the rotation directions.
