【摘要】 在研究嵌入式系统软件功耗优化技术的基础之上,开发一个完整的基于μC/OS-Ⅱ的GSM终端系统。以降低该系统软件的功耗为目标,通过软件设置系统的低功耗模式,减小系统空闲时间的电量消耗。最后通过功率测量仪对优化前后的系统进行功耗测试。实验结果表明,低功耗模式比系统空闲状态下功耗下降50.86%左右。更多还原

【Abstract】 Based on embedded software power optimization technology,a GSM terminal system base on μC/OS-II is developed to reduce the power generated by the system software.Low-power mode is set through software,in order to reduce power consumption of idle time.Finally,power measuring instrument is used to test power consumption of the system before and after optimization.Experimental results show that power consumption of the system in low power mode declines around 50.86%.更多还原
