软件功耗与软件优化技术

Software Energy Consumption and Software Optmization Technology

无论设计制造还是使用计算机,功耗问题一直倍受关注。随着嵌入式系统的深入研究和广泛应用,计算机系统的功耗问题越来越突出。过去我们对降低计算机硬件功耗给予较多的关注,现在我们必须对降低由软件引起的功率损耗给予足够的重视。特别是当计算机芯片技术发展至几纳米级的时候,研究降低软件功耗的途径和方法尤为重要。对于软件质量的评价,也应将软件功耗作为综合评价软件代码优化性能的一个指标。

Not only in designing and making computer but also in using it, the problem of energy consumption has been paid close attention to extremely all the time. With further investigation and extensive application of the embedded system, the consumption question of the computer system is more and more outstanding. We paid more concerns in reducing the computer hardware consumption in the past, we must pay enough attention in reducing the power consumption caused by .software now. Especially when the chip technology of the computer develops to several nanometers, it is particularly important to study the way and method of reducing the software consumption. And when we comprehensively appraise on the quality of the software, we also should regard the software consumption as a guid line of optimizing performance of software code.
