Energy profiler for hardware/software co-design

The increasing popularity of low power computing drives the need for increasing battery life-time by power-optimizing application programs. This requires a tool capable of providing a system-level energy model. We present a methodology for simulating and profiling energy consumed by software applications running on computing systems. The uniqueness of our framework lies in its ability to capture at a fine granularity, power behavior of the software executing on the system as well as of each of the hardware components in the system and its applicability to a wide variety of computing systems. We demonstrate our work on a real world platform, the Itsy, a handheld computer developed by Compaq´s Western Research Labs.
