규칙적인 구조를 갖는 8×8 Discrete Consine Transform 알고리즘 및 아키텍쳐
柳在熙,趙鍾翼 弘益大學校 科學基術硏究所 1999 科學技術硏究論文集 Vol.10 No.2
기존의 DCT 알고리즘은 불규칙적인 구조로 이루어져, VLSI 구현상 여러가지 문제가 발생되었다. 그래서 모든 버터플라이 스테이지가 동일한 구조를 갖고, 규칙적인 버터플라이 스테이지를 바탕으로 연산함으로써, VLSI 구현을 용이하게 할 수 있는 8×8 DCT 프로세서의 알고리즘 및 아키텍쳐가 제안되었다. 제안된 DCT 시스템은 모두 간단하며 동일한 구조를 갖는 PE(Processing Element)칩의 반복사용으로 구성할 수 있도록 설계되며 계산 속도(성능)와 하드웨어의 양(구현비용)의 조절에 따라 다양한 분야에 구현이 가능하다.
