개인이동기기의 사용이 증가함에 따라, 보다 효율적이고 편리한 이동시스템을 위한 많은 연구가 진행되고 있다. 특히 에너지 소모의 절감에 대한 연구는 이동기기의 기동성을 위해 중요한 문제이다. 동적전압조정은 이동기기의 에너지 소모를 가장 많이 차지하는 요소 중 하나인 프로세서의 전력을 효율적으로 관리하고 감소시킬 수 있는 방법이다. 본 논문에서는 MPEG 프레임별 복호시간의 차이를 이용한 동적전압조정 알고리듬을 통해 프로세서가 WPEG디코더를 실행할 때 전력소모를 최소화하는 과정을 프로세서 시뮬레이터를 통해 확인한다. 논문에서 제안한 동적전압조정 알고리듬은 원래의 프로세서 에너지 소모와 비교하여 약 70%-85%의 감소효과를 볼 수 있었다.
