- fdej 9y agoNo. Typical implementations use polynomial evaluation and range reduction. The advantage of CORDIC is that it only uses shifts and additions, and no multiplications. The disadvantage of CORDIC is that it converges very slowly. On modern hardware where multiplication is blazingly fast, CORDIC no longer makes sense.
