Power Analysis Workflow With Intel® Energy Profiler

1.

Install VTune Amplifier for Systems

Install the full-scale VTune Amplifier product on the host system.

2.

Set up remote system for analysis

Connect the host to the target system:

• For an Android device, use ADB communication. Preparing a Target Android System for Remote Analysis
• For a Windows device, use Connected Standby with WDTF.

3.

On the target system, install Intel SoC Watch/WuWatch collector

1. On the host, unzip the remote target package, system_studio_target.tgz, located, by default, in the <system_studio_install_dir>\Targets directory.

2. Depending on your Intel architecture, run the required install script:

   • socwatch_android_vx.x.x/socwatch_android_install.bat or socwatch_android_vx.x.x/socwatch_android_install.sh from a Cygwin window

   • wuwatch_android/wuwatch_android_install

   By default, the script installs the collector executables to the /data\socwatch directory on the target system. Use the -d option to select a different install directory and the -s option to define a specific target device if multiple devices are connected to the host.

   Note

   See the Intel SoC Watch User's Guide for detailed instructions on building and loading the power driver for your target system.

4.

Build (if required) and load power driver

1. (Optional) Build your driver on the host.

2. Load the driver to the target system.

3. Confirm the driver is loaded.

4.

Configure and run Intel Energy Profiler analysis

1. Set up the collection environment.

2. Configure and run the data collection with Intel SoC Watch collector.

   The result *.sww1\en file is saved to the results directory.

3. Pull the result file to the host.

5.

Import the collected data to VTune Amplifier GUI

1. Launch VTune Amplifier GUI on the host.

2. Open/Create a project.

3. Import the *.sw1 file to the project.

   Intel Energy Profiler analysis data is opened in the default Platform Power Analysis viewpoint.
