컴퓨터 시스템을 위한 소프트웨어 개발에 있어 성능 최적화는 하드웨어 및 운영체제에 대한 전문 지식과 다양한 상황을 고려할 수 있는 숙련을 필요로 하는 매우 어려운 작업으로 알려져 있다. 특히, 임베디드 시스템의 경우 사용되는 하드웨어와 운영체제의 종류가 매우 다양하여 임베디드 소프트웨어의 성능 최적화에는 더욱 많은 시간과 노력이 요구된다. 자가적응형 컴퓨팅은 소프트웨어 개발에 있어 성능 최적화 작업 노력을 최소화하기 위한 기술로 소프트웨어 실행을 실시간으로 감시하면서 소프트웨어 실행에 관여하는 다양한 컴퓨터 시스템 리소스들을 제어하여 소프트웨어가 요구하는 성능을 자동으로 맞춰주는 컴퓨팅 기술이다. 본고에서는 자가적응형 컴퓨팅 기술 현황을 살펴본 후 임베디드 디바이스를 위한 자가적응형 컴퓨팅 기술 개발 사례를 소개한다.
