Measurement Modes

Optimizing embedded applications for overall efficiency should be an integral part of the development process as it is important to understand how peripherals, software algorithms, and power saving modes work together.

While measuring power with debug has benefits, the Arm CoreSight™ debug logic makes measuring deep sleep modes impossible. Therefore, µVision supports energy measurement in two ways:

Debug Energy measurement with debug allows you to:

  • observe power consumption profile synchronized with the trace data and program events
  • have full debug control over the program execution
  • obtain aggregated measurement data using Event Statistics.

Debug Energy Measurement without debug:

  • has no impact of the debug connection on the measurement results.
  • enables consumption measurement in deep sleep states.
  • can be done on any target and without source code required.
