Abstract

The most important design factor for portable devices is power consumption. In this paper, in the early design stage of a mobile device which measures temperature and humidity a power consumption model will be proposed and then the overall power consumption will be estimated based on this model. We will verify previously the correctness of such estimated power consumption before implementation of the real device. That is our proposed design methodology based on power consumption model. An improved design method for efficiently reducing the current consumption in the idle mode is also presented. By implementing a real prototype of the mobile device for measuring temperature and humidity, the correctness of our proposed design methodology based on power consumption modeling will be verified.

휴대용 기기에서 가장 중요한 설계 요소는 소비 전력이다. 본 논문에서는 휴대용 온습도 측정기 설계 초기에 전력 소비 모델을 제시하고, 제시된 모델에 입각해 휴대용 온습도 측정기의 소비 전력을 설계한다. 이렇게 설계된 휴대용 온습도 측정기의 소비 전력을 사전 검증함으로써 제품 구현 전에 설계 검증을 완료하기 위한 전력 소비 설계 모델링 방안을 제시하고자 한다. 한편, 대기 모드에서 소비 전류를 효과적으로 감소시키기 위한 전력 소비 설계 개선 방안도 제시한다. 휴대용 온습도 측정기 구현을 통해 전력 소비 모델링에 입각한 설계 방법론의 타당성을 확인할 것이다.
