    Abstract: A method for generating a power consumption and energy usage model for a computing device includes monitoring of the power consumption of the computing device with an external power monitor when the computing device is in a base power state, monitoring of the power consumption of the computing device during execution of a system call with a processor that interacts with a component in the computing device, and monitoring the power state of the computing device before the computing device returns to the base power state. The method further includes generating a finite state machine model of the power states and transitions between power states to model the power activities and energy consumption of the computing device in the absence of an external power monitor.

    Abstract: A method for generating an energy usage profile for a software program executed in a computing device includes generating a call trace of an executed system call, identifying a first power consumption and duration of a first power state due to the first system call using a model, identifying a second power consumption and duration of a second power state based on the model, and generating an energy usage profile for the software program. The energy usage profile includes energy consumption of the computing device for the system call based on the first power consumption level multiplied by the first duration and the second power consumption level multiplied by the second duration associated an identifier for the call trace.

    Abstract: Embodiments of the present invention provide a system and methods for detecting power bugs. In one embodiment, a computer-implemented method for analyzing a computer code includes generating a control flow graph for at least a portion of the computer code at a processor. The method further includes identifying power bugs by traversing the control flow graph if the control flow graph exits without performing a function call to deactivate power to any component of a device configured to execute computer executable instructions based on the computer code after performing a function call to activate power.
