嵌入式智能系统底电流的调试方法

Method of Debugging Low Power Consumption Embedded System

本文针对如何获得嵌入式系统低功耗状态下的准确电流值的方法进行了阐述和验证。硬件使用Intel PXA270芯片构成的最小系统为基础,提出了软件先在bootloader中进行系统进入低功耗状态和退出低功耗状态的调试方法。分析了最小系统睡眠时功耗值与配有其它外围设备的嵌入式系统睡眠时功耗值相同的原因。

This paper presents a method of debugging a low power consumption intelligent embedded system. The hardware of the debug platform is based on the Intel PXA270 minimum system; and have presented the way to enter and exit the low power status in the Boodoader configured by software. This paper has also analyzed the reason that the embedded minimum system＇s power consumption in sleeping mode matches the embedded system which having other peripherals＇ power consumption in sleeping mode.
