The µVision ARM simulator contains an Execution Profiler that records timing statistics for the complete program code. The display is enabled via the menu command Debug — Execution Profiling. You may select between Call (shows number of executions) and Time (shows execution timing) display. Point with the mouse to a specific entry for complete information display in a tool tip window.
View in C Source Files. By using the editor Source Outlining features, you may collapse several source code lines to get a summarize of the execution times of this source block.
View in the disassembly window gives execution statistics for single assembler instructions.
Note
- The execution time is calculated based on the current clock setting. When the code is executed multiple times using different execution clock values, wrong execution time results are generated.
- The Exection Profiler is currently only available in the ARM simulator.
