Zusammenfassung:	A method for generating a trigonometric function using a coordinate rotation digital computer (CORDIC) algorithm is disclosed. The method includes a first step of extracting a plurality of candidate angles for generating one target rotation angle, a second step of applying at least one of clockwise rotation, counterclockwise rotation, and no rotation to each of the plurality of extracted candidate angles, and a third step of performing a CORDIC operation through iteration for each of the plurality of candidate angles to which at least one of clockwise rotation, counterclockwise rotation, and no rotation is applied. 코딕(CORDIC, Coordinate Rotation Digital Computer) 알고리즘을 이용하여 삼각함수를 생성하는 방법이 개시된다. 본 방법은 하나의 목표 회전 각도를 생성하기 위한 복수의 후보 각도를 추출하는 제1 단계, 추출된 복수의 후보 각도 각각에 대하여 시계 방향 회전, 반시계 방향 회전, 및 무회전 중 적어도 하나를 적용하는 제2 단계, 및 시계 방향 회전, 반시계 방향 회전, 및 무회전 중 적어도 하나가 적용된 복수의 후보 각도 각각에 대한 반복(Iteration)을 통하여 코딕 연산을 수행하는 제3 단계를 포함한다.
