为了降低嵌入式应用系统的功耗和成本,设计实现了一种应用于低功耗嵌入式处理器的功耗动态管理策略.该功耗动态管理策略包括多工作模式切换、动态频率调节、动态电压调节和快速可变的电压供给单元全集成,在满足功能和性能要求的基础上,根据处理器执行任务的需求变化,切换处理器的工作模式,动态调节工作频率与工作电压,降低功耗;快速可变的电压供给单元也集成于处理器中,支持工作电压的实时快速调节,降低系统成本.基于嵌入式应用系统样机的验证结果表明,应用系统执行不同的进程任务时,功耗均有效下降.在嵌入式应用系统中采用该功耗动态管理策略,能够有效降低系统的功耗与成本.
Abstract:
In order to reduce the power consumption and cost of an embedded application system, a power dynamic management strategy for a low-power embedded microprocessor is designed. The power dynamic management strategy comprises multi-mode switch, dynamic frequency regulation, dynamic voltage regulation and full integration of rapid variable voltage supply unit. Based on the function and performance requirement, the operating mode switch and the regulation of operating frequency and voltage are realized to reduce the power consumption according to the requirement variation of task. The rapid variable voltage supply unit is also integrated into the microprocessor, which supports the intelligent real-time supply voltage regulation and reduces cost. The management strategy is tested by an embedded application system prototype, and the experimental results show that the power consumption can be effectively reduced when executing different tasks. Therefore, when the power dynamic management strategy is applied to embedded application systems, the power consumption and cost can be reduced effectively.
