본 논문은 빠른 벡터 회전과 사인/코사인 계산을 위한 상수 스케일 인자 기수-2-4-8 CORDIC 알고리즘을 제시합니다. CORDIC 알고리즘은 다양한 기본 기능을 계산하기 위한 잘 알려진 하드웨어 알고리즘입니다. 그러나 계산의 순차적 특성으로 인해 실시간 신호 처리 애플리케이션에는 처리 지연 시간을 크게 줄여야 합니다. 제안된 radix-2-4-8 CORDIC 알고리즘은 연산 중 계산 기수를 동적으로 변경하여 37비트 정밀도에 대해 반복 횟수를 64% 감소시키는 것이 가능하다. 본 문서에서는 실제 디지털 신호 프로세서에 설치될 수 있는 radix-2-4-8 CORDIC 장치의 하드웨어 구현에 대해서도 설명합니다.

Abstract: This paper presents a constant-scale-factor radix-2-4-8 CORDIC algorithm for fast vector rotation and sine/cosine computation. The CORDIC algorithm is a well-known hardware algorithm for computing various elementary functions. Due to its sequential nature of computation, however, significant reduction in processing latency is required for real-time signal processing applications. The proposed radix-2-4-8 CORDIC algorithm dynamically changes the radix of computation during operation, and makes possible the reduction in the number of iterations by 37% for 64-bit precision. This paper also describes the hardware implementation of radix-2-4-8 CORDIC unit that can be installed into practical digital signal processors.
