This paper describes a new direction sequence generation method for the circular CORDIC algorithm. A conventional approach employs an angle computation algorithm to control the direction of rotation in the form of a sign sequence, where the sign generation is a bottle-neck for the fast implementations. The proposed method reduces the number of sequential computations by employing a new angle representation model and linearizing the arctangent function in small angles. The direction sequence can… CONTINUE READING
