Low power consumption is one of the most important design factors for embedded systems, especially in this global warming era. Besides the computing elements, the memory access, communication over system bus or network links and device access all consume energy which cannot be neglected. Therefore, low-power design should consider the system-level energy consumption. Most system-level energy scheduling algorithms focus on systems with single CPU or homogeneous systems. Advanced embedded systems are becoming more and more complex. They are networked and may be composed of subsystems with various processors like single-core processors, multi-core processors, GPU, E-Textiles, etc. The networked and heterogeneous nature of such systems poses a great challenge on system-level low-power design.

低功耗是嵌入式系统最重要的设计因素之一，特别是在这个全球变暖的时代。 除了计算元件之外，存储器访问、通过系统总线或网络链路的通信以及设备访问都消耗不可忽视的能量。 因此，低功耗设计应考虑系统级能耗。 大多数系统级能量调度算法都集中在单CPU系统或同构系统上。 先进的嵌入式系统正变得越来越复杂。它们是网络化的，可能由具有各种处理器的子系统组成，如单核处理器，多核处理器，GPU，E-Textiles等。这些系统的网络化和异构性对系统级低功耗设计提出了很大的挑战。
