최근 모바일 멀티미디어 기기들의 사용이 증가하면서 고성능 멀티미디어 프로세서에 대한 필요성이 높아지고 있는 추세이다. DSP 기반의 시스템은 범용성에 기인하여 다양한 응용 분야에서 사용될 수 있으나 주문형반도체 보다 높은 가격과 전력소모 그리고 낮은 성능을 가진다. ASIP는 주문형반도체의 저비용, 저전력, 고성능과 범용 프로세서의 유연성이 결합된 새로운 형태의 프로세서로서, 단일 칩 상에 H.264, VC-1, AVS, MPEG 등과 같은 다양한 멀티미디어 비디오 표준 및 OFDM과 같은 통신 시스템을 지원하고 또한 고성능의 처리율과 계산량을 요구하는 차세대 비디오 표준의 구현을 위한 효과적인 해결책으로 주목되고 있다. 본 기술 문서에서는 ASIP의 특징과 애플리케이션의 가속 방법, ASIP을 위한 컴파일러 설계 및 응용에 관하여 기술한다.
