2.4.7.1 Measuring the Program Execution Cycle Count

This section explains the function of measuring the number of program execution

cycles.

■Measurement Items

This function measures the number of program execution cycles or real-time. The measurement is
performed whenever a program is executed, and the measurement result displays the following values:
The measurement is performed whenever a program is executed, and the measurement result displays the
following two values:
- The number of execution cycles or real-time for the previous program execution
The maximum number of cycles that can be measured is 288,230,376,151,711,743 (2 to the power of
58 - 1).
- The total number of execution cycles or real-time after the previous clear operation
The maximum number of cycles that can be measured is 18,446,744,073,709,551,615 (2 to the power
of 64 - 1).
- Real-time measurement resolution
This depends on the execution cycle conversion frequency set for measurement unit. For details, refer
to "4.4.14.2 Performance (Emulator Debugger [MB2100-01])" of "SOFTUNE Workbench Operation
Manual".
