Introduction

The PIAnalyser Carbide.c++ Extension is used to graph, measure and analyze the performance data collected from a handheld device. The data for the analysis is collected from the device as sampler traces either

• with the PIProfiler tool running on-device, or
• remotely from Carbide.c++, via a TraceViewer connection using the Performance Investigator Wizard.

The data is then saved into a Profiler data (.dat) file and imported to Carbide. Opening the Profiler data file in Carbide.c++ will launch the PIAnalyser, and present graphs and tables that enable performance analysis based on collected data.

Features

PIAnalyser lets you collect, view and analyze performance data on the following:

• CPU
  • Thread load
  • Binary load
  • Function load
  • Function calls
• Memory usage
• Power usage

How to obtain

Install latest PDT.

How to get started

To be able to analyze PIProfiler data, you need capture the data and import it to PIAnalyser.

Performance Investigator Setup for Remote Profiling from Carbide with Performance Investigator Import Wizard
	Install Nokia Ovi Suite on the PC Install the latest Nokia Ovi Suite on your PC and launch Carbide.c++ IDE. Connect a USB cable Connect a USB cable to the PC and then to the target device.
	Start the Performance Investigator Import Wizard Start the Import Wizard in Carbide.c++ by selecting Carbide > Performance Investigator
	Import data from device by tracing On the Select Profiler Data Files page, select to get profiler data From Device via TraceViewer.
	Check connection settings Before you start tracing, check the connections settings. Select Connection settings to open the TraceViewer Connections Setting dialog. After checking and saving the connection settings, click Refresh Plug-ins List. If the connection to the target device is working correctly, a list of the available plug-ins appears.
	Set plug-ins for tracing and prefix for created file Select the plug-ins you want to trace from the Select Plug-ins for Tracing list. Enter the file prefix to be used for the trace data file. Run the trace Click Start Tracing to begin and carry out the use case with your application. When you are finished with the use case, click Stop Tracing. A new trace file name appears in the Created Profiler Data Files list. If you wish you can run another trace. Just enter a new prefix for the second file and change the setting if you wish. Finish the import Click Next to continue with the import. For detailed instructions, click the question mark icon in the wizard to open the Help.
	Open the file for analysis If you imported only one file, the data will open directly to the PI Analyser view. If you imported several files, they will be listed in the PI view and you can double click on an item to view and analyze it in PI Analyser.

Performance Investigator Setup for On-device Profiling with PI Profiler
	Install PI Profiler Transfer and install S60_3_1_PIProfiler_v2_x_x.sisx file to the target device. Setup and Start Profiler Setup Profiler on the target device and capture application data. See Performance Investigator Profiler How to get started for more instructions. Transfer Profiler Data File to PC Transfer the profiler data file to the PC by USB, Bluetooth, or serial interface connection.
	Import Profiler Data File to Analyser Use the Performance Investigator Import Wizard to import profiler data file into Carbide.c++ for analysis. 1. Start the wizard in Carbide.c++ by selecting Carbide > Performance investigator 2. On the Select Profiler Data Files page, select to get profiler data From File System, and continue from there. Click the question mark icon to view the Help for detailed instructions.
	Analyze Performance Data Analyze the profiled application data within Pi Analyser Carbide.c++ extension. If you imported only one file, the data will open directly to the PI Analyser view. If you imported several files, they will be listed in the PI view and you can double click on an item to view and analyse it in PI Analyser.
