본고에서는 멀티미디어 응용을 위한 멀티 코어 가상 플랫폼 설계 및 검증 방법에 대해서 기술한다. 최근에 멀티미디어 응용인 MPEG-4, H.264, HEVC(High Efficiency Video Coding), 3D 및 홀로그램과 같은 대용량 데이터를 처리하기 위해 다수 개의 코어로 구성된 멀티 코어 플랫폼을 사용한다. 기존의 RTL(Register Transfer Level) 기반의 멀티 코어 플랫폼에서 멀티미디어 응용을 설계하고 검증하는데 시뮬레이션 시간에 의한 제약 사항이 존재한다. 이를 해결하기 위해 시스템 수준에서 하드웨어의 SW 모델로 구성된 가상 플랫폼을 사용한다. 가상 플랫폼은 기존의 RTL 플랫폼보다 100~200배 빠른 고속 시뮬레이션이 가능하므로 멀티미디어 응용에 따른 성능 분석 및 구조 탐색을 통해서 시스템 성능을 향상 시킬 수 있다. 본고에서는 8~32개 멀티 코어 가상 플랫폼에 H.264 디코더를 적용하여 성능 분석하는 방법과 실험 결과에 대해서 기술한다.
