| Wearable computer is a mobile computing equipment for individual, which is famous for miniature, wearable, man-machine close integration and being in conjunction with person . However, wearable computing system still has many problems, such as power consumption, heat dissipation and volume etc. Among them, because of the limited capacity of the mobile power supply, power consumption limitation has became one of the most important factors to hinder the development of mobile computing system. Currently, researchers have been doing a lot in this field but far from meeting the needs.Based on power consumption of wearable computing system and combined with the research and design of wearable computer, this thesis is focusing on a relatively deep study of low power consumption design of wearable computing system to offer some hints for wearable computing low power design from software angle.The body of this thesis mainly covers the following two aspects:First, concerning the soft design of low power consumption for wearable computing system, instruction application and program design is an important technical means for low power consumption design of wearable computing system and even general computing system. Therefore, in order to ensure system real time needs and decrease software power consumption of wearable computing system, this thesis proceed the research from two parts: one is seeking low power consumption design to achieve efficient running via choosing and applying instructions; the other is adopting the proceeding optimization attemperment to realize efficient and low power consumption software attemperment.Second, power consumption management, another important technical means, exerts a great influence on low power consumption running of power management system. This thesis introduces the power consumption management mechanism of wearable computing system and analyzes the power consumption management models of main power consumption modules then does a thorough study on the optimization configuration of power consumption cut time. Since power consumption cut time... |
