Execution Profiler

The Execution Profiler records timing and execution statistics about instructions for the complete program code. To display the values, use Show Time or Show Calls from the menu Debug — Execution Profiling. The values are displayed in the Editor and Disassembly Window.

  • Hover with the mouse over a value to view the complete information in a tool-tip window.
  • Use the editor's Outlining features to collapse source code lines. Single instruction statistics are summarized and are displayed as one value for this block.

Execution Profiling Showing Execution Time

Execution Profiling Showing Call Count

Note

  • Enable the option ETM Trace Enable when debugging on hardware.
  • The execution time is calculated based on the current Xtal (MHz) clock setting. When the code is executed multiple times using different execution clock values, incorrect statistics are generated.
  • The Execution Profiler is available for the MDK-ARM toolchain only.
