Abstract:

In order to effectively manage embedded systems, especially reduce power consumption of the mobile terminal,this paper proposes a power management scheme,which is based on the design of a more refined dynamic power management scheme. It is based on Application Program Interface ( API) behavioral characteristics,using BP neural network algorithm to predict the type of application,through the effective prediction of application types. It can adjust the system state in advance,without affecting system performance,effectively reducing power consumption,realize the power of real-time embedded devices and dynamic management.

Key words: embedded system, dynamic power management, Application Programming Interface ( API), BP neural network algorithm, Cpufreq module
