Current nano-meter scale VLSI technology has advanced to a point where the amount of power consumed in a typical VLSI chip under maximum performance situation could cause overheat and even become destructive. Traditional power management solutions aimed at distributing a prescribed amount of power to specific circuit blocks over specific periods of time, via control software. While some form of power optimization can be achieved by taking into account the clock frequency, supply voltage and temperature, many issues remains. This includes the development of the new power/energy management strategies that takes process variations, temperature and aging effects, dynamics of the control loops, and the efficiency of the entire system into account.

目前的纳米级超大规模集成电路技术已经发展到这样的程度，即在最大性能情况下，典型的超大规模集成电路芯片中消耗的功率量可能导致过热，甚至变得具有破坏性。传统的电源管理解决方案旨在通过控制软件在特定时间段内将规定量的功率分配给特定电路块。虽然可以通过考虑时钟频率、电源电压和温度来实现某种形式的功率优化，但仍然存在许多问题。这包括开发新的功率/能量管理策略，该策略将过程变化、温度和老化效应、控制回路的动态以及整个系统的效率考虑在内。
