基于S3C44B0X的低功耗移动采集终端设计

Low Power Consumption Design of Mobile Data Collector Based on S3C44B0X

在嵌入式移动设备设计和使用中,系统的功耗是一项非常重要的性能指标。高效的低功耗设计能降低系统功耗,延长系统的待机时间和电池使用寿命。实现系统功耗的最小化,对于任何一种嵌入式设备都有很重要的意义。为实现这一目的,需要在硬件设计和软件设计两方面综合考虑。叙述了在基于ARM7内核的CPU-S3C44B0X上实现低功耗设计的办法,并应用于已完成的移动数据采集终端设计中。实践证明,系统空闲时间的功耗得到大幅度降低,待机时间延长。

The system power is very important in design of embedded mobile equipment. Low power design can reduce system power consumption efficiency and prolong the battery life. Have to consider the hardware and software design seriously to achieve this target. Discusses the method to realize low power consumption on the system which is based on the S3C44B0X, And this method had been used in the design of mobile data collector. The result shoves that the method is effective.
