This paper designs and implements a software prober to support a more effective power analysis for Linux-based embedded systems by using power consumption data measured in hardware. The proposed software prober, which is included in a target system as a module, collects power data and provides a service to discover major power consumers in user functions of applications or kernel functions through time synchronization between the power data measured in hardware and software. In addition, we verified usefulness of the implemented software prober by running user applications on target systems.
