| 摘 要： | 针对移动嵌入式实时系统的低功耗设计,提出一种改进的应用情景检测的安全任务内电压调度算法。该算法利用任务程序少数参数的值域定义情景并在任务处理过程中进行检测,因而在处理在线的情况下,可较为精确地预测后续处理的部分路径,优化地调度处理电压。通过所提出的情景检测点设置算法,在任务程序中找到检测参数情景最合适的点,给出算法的实现方法。通过仿真实验证明该算法能有效地降低任务处理能耗。

| Abstract: | In this paper,an improved safe intra-task voltage scheduling algorithm using scenario detection is proposed for the energy-efficient designs of the mobile embedded real-time systems.The ranges of few parameters in the program of the task are used to describe scenarios which are detected in the process of the task execution,and some of the remaining execution paths can accurately be predicted in the on-line mode which can optimize the voltage scheduling.Furthermore,the most reasonable points in the program t... |
