Abstract
본 논문에서는 고해상도(Full-HD)급의 비디오를 처리할 수 있는 고효율 비디오 코딩(HEVC) 표준을 따르는 인코더 IP 설계에 대하여 기술한다. 설계된 IP는 HEVC 메인 프로파일 4.1급에 해당되며, 프레임 레이트는 60 fps 로 실시간 인코딩 가능하다. 하드웨어 및 소프트웨어 IP 설계 전에 C 언어로 전체 참조 모델을 개발하였으며 고속처리를 위한 병렬처리구조와 저 전력을 위한 스킵모드를 제안하였다. 또한 IP 관련 펌웨어 및 드라이버 프로그램을 작성하였다. IP 검증을 위한 플랫폼을 개발하였고 설계된 통합 IP를 FPGA 보드로 구현하여 다양한 영상에 대하여 여러 인코딩 조건에서 기능 및 성능을 검증하였다. HM-13.0대비 동일 PSNR에서 약 35% 정도의 비트율 감소와 저전력 모드에서 약 25% 정도의 전력 소모 감소 효과가 있었다.
