Measure Power During Test

Registered by Zach Pfeffer on 2012-07-26

Why?
Measuring power consumption during a test on target allows developers to more easily optimize for power.

Context?
This is part of the larger ARM benchmarking effort.

What gets produced?
A National Instruments Virtual Instrument (VI) that will take a command through the VI, start the power measurement, sense when the test ends, and stop the power measurement.

Where will the work get put?
On android.git.linaro.org
