Research on low power application software in Linux system

Nowadays many portable devices installed operating systems to complete the complex function and resource management, including power management. This article from the perspective of application tasks, analyzes the task´s characteristics and their mutual relations, puts forward a task centralized wake-up strategy and an optimized algorithm of consumers and producers. Build the application software of low-power processor model, and validate the model by video play in Linux system, which proves that the model could reduce the power consumption of processor without influencing the operation efficiency of software.
