嵌入式系统的软件低功耗技术实现策略

Implementation Strategy of Software Low-Power Technologies in Embedded Systems

在目前全球倡导"低碳经济"的背景下,大量嵌入式系统的电力消耗问题日益引起人们的关注,功耗已成为嵌入式系统设计的重要瓶颈。论文在研究国内外嵌入式系统低功耗技术发展现状的基础上,根据嵌入式系统的软件组成结构,将软件低功耗技术划分为三个层次进行分类描述,阐明了各层次上低功耗技术面临的问题、主要解决方法及应用情况,较完整地展现了嵌入式系统软件低功耗技术的全貌,并探讨了低功耗技术未来的一些发展趋势。

Nowadays as low carbon economy is advocated worldwide,the electricity consumption caused by a huge number of embedded systems is gaining more and more attentions,and power consumption has become a critical issue in embedded system design.After past work of low power consumption technologies in embedded systems is explored,according to the software constituents of embedded systems,this paper divides low power consumption technologies into three levels,in which,the encountered problems,major solutions and applications are clarified.A full vision about low power consumption technologies in embedded systems is described.Finally,this paper discusses some trends of software low power consumption technologies in the future.
