CHAPTER2 Dependence Functions
2.4.7 Measuring the Program Execution Time
This section explains the function to measure the program execution time.
■ Measured Items
The emulator debugger (MB2100-01) can measure the following two items for the user program execution
time.
• Time measurement
Measures the time from start of program execution to end.
For details, refer to "2.4.7.1 Measuring the Program Execution Cycle Count".
• Performance measurement
Measures the time between 2 events where the program execution passes.
For details, refer to "2.4.7.2 Measuring Event-to-Event Execution Cycle Count [Performance
Measurement]".
■ Measurement unit
The following two measurement units are available for both execution time measurement and performance
measurement.
Measurement unit can be set as follows.
• Dialog
- Measurement Unit Dialog
For details, refer to "4.4.14.2 Performance (Emulator Debugger [MB2100-01])" or "4.6.8.1
Measurement Unit for Execution Time Measurement" of "SOFTUNE Workbench Operation Manual".
• Command
- SET TIMERSCALE
For details, refer to "1.64 SET TIMERSCALE" of "SOFTUNE Workbench Command Reference
Manual".
Note:
Measurement unit setting is common to both time measurement and performance measurement.
Execution cycle measurement : Measures by the number of execution cycles.
Also, the number of measured execution cycles can be
converted into real time.
This is different from an actual measurement, however, it is
an indication of real-time when real-time can not be
measured.
Real-time measurement : Measures in real-time.
This is available only for certain products.
