The CORDIC Algorithm: New Results for Fast VLSI Implementation

  title={The CORDIC Algorithm: New Results for Fast VLSI Implementation},
  author={Jean Duprat and Jean-Michel Muller},
  journal={IEEE Trans. Computers},
After a brief survey on the CORDIC algorithm, we give some new results which enable fast and easy signeddigit implementation of CORDIC, without modifying the basic iteration step. A slight modification would make it possible to use carry save representation of numbers, instead of signed-digit one. Our method, called branching CORDIC method, consists of performing in parallel two classic CORDIC rotations. It gives a constant normalization factor. Then, we propose an on-line implementation of our… CONTINUE READING
