| 摘 要： | 动态电压调节是一种有效的运用于实时嵌入式系统中的低功耗技术。实时嵌入式系统DVS技术不仅要实现系统功耗的降低,同时也要兼顾系统的实时性,满足任务的截止时间限。该文针对近几年实时嵌入式系统中DVS策略,首先介绍实时系统中DVS策略模型,对主流策略进行分类比较,并且对相应策略进行仿真,DVS策略可以取得10%～40%的能耗节省。 |
| 关 键 词： | 实时系统 DVS策略 模型 比较 仿真 |

| Abstract: | Dynamic voltage scaling (DVS) is an effective methodology for low power design in real-time embedded systems.DVS for real-time embedded systems is aimed for not only minimizing the system energy consumption,but meeting the deadline of all tasks.In this paper,in term of DVS for real-time embedded systems in recent years,we first describe the models of DVS algorithms.To classify several key DVS algorithms,compare them with each other and simulate the related DVS,we find that DVS algorithms are shown to reduce... |
