Abstract :
We propose a novel system level power estimation method for wireless communication devices. The method estimates the power consumption of a processor and external devices by only using OS level profile information (i.e., the system call information), and is applicable to both off-line and online power optimizations. Evaluations on a commercial wireless communication device showed that the method achieves an estimation error of less than 10%.
