摘要

针对低功耗嵌入式微处理器，提出了一种具有泄漏功率补偿效果的动态电压和频率管理方案，该方案能够自主控制时钟频率(在0.5 MHz步进时为8 ~ 123 MHz)和自适应控制电压(在5 mV步进时为0.9 ~ 1.6 V)。在个人信息管理(PIM)应用程序中实现82%的功耗降低。

Dynamic voltage and frequency management for a low-power embedded microprocessor

A dynamic voltage and frequency management scheme that autonomously controls the clock frequency (8 to 123 MHz at 0.5 MHz step) and adaptively controls the voltage (0.9 to 1.6 V at 5 mV step) with a leakage power compensation effect is developed for a low-power embedded microprocessor. It achieves 82% power reduction in personal information manager (PIM) application.
