| Abstract: | In order to deploy low power consumption embedded systems and save energy, this article analyses the origin and classification of power consumption in embedded systems, puts forward some design methods of power management which include scheme of the holistic power, selection of CPU, design of interface circuit, strategy of power supply circuit and dynamic power management. Based on the methods mentioned above, this paper takes μC/OS-Ⅱ and ARM LPC2131 as the platform to prove the validity and feasibility of the design methods. The results show that the power consumption of embedded systems will be greatly decreased when the proper power management strategy is adopted. |
