본 논문에서는 3D 그래픽스(graphics), H.264/H.263/MPEG-4 같은 동영상 코덱, JPEG 혹은 JPEG2000 같은 정지영상 코덱, MP3 같은 오디오 코덱 등 다양한 멀티미디어 관련 기술을 효율적으로 구현하기 위한 재구성형 병렬 프로세서 구조가 제안된다. 제안된 구조는 메모리와 프로세서를 직접 연결하여 메모리 접근 시간과 소비전력를 감소시키고, 3D 그래픽스 처리 과정 중 기하 단계의 부동소수점 연산을 지원한다. 또한 분할 SIMD(partitioned SIMD) 방식을 사용하여 하드웨어 비용을 줄이고, 명령어(instruction)의 조건부 실행(conditional execution)을 지원하여 알고리듬 개발이 용이하다.
