嵌入式系统的低功耗设计需要全面分析各方面因素, 统筹规划。在设计之初, 各个因素拄拄是相互制约、

相互影响的, 一个降低系统功耗的措施有时会带来其他方面的“ 负效应” 。因此, 降低系统整体功耗, 需要

仔细分析和计算。本文从硬件和应用软件设计两个方面, 阐述一个以单片机为核心的嵌入式系统低功耗

设计时所需考虑的一些问题-Low-power embedded system design requires a comprehensive analysis of various factors, overall planning. Beginning in the design of various factors, Zhu Zhu is mutual restraint, mutual influence, and a lower system power consumption measures are sometimes bring other aspects of the " negative effect."　Therefore, reducing overall system power consumption, require careful analysis and calculation. In this paper, hardware and application software design, two aspects to explain a microcontroller as its core low-power embedded system design a number of issues need to be considered
