Introduction

Which part of the programcode causes the highest power consumption? Which influence has a code modification to the application′s power consumption?

The integrated measurement solution for energy profiling gives developers a powerful, easy-to-use tool to answer these questions.

To acquire the data for current or voltage gradients a TRACE32 PowerTrace II or PowerIntegrator can be extended with a TRACE32 AnalogProbe.

The analog measurements are timecorrelated with the application′s programflow. This is the key to track down unexpected powerpeaks to a certain line of code or to detect power hungry functions and tasks.
