2.4.7.2 Measuring Event-to-Event Execution Cycle Count
[Performance Measurement]
This section explains how to measure the execution cycle count between two events.
■ Performance Measurement
The emulator debugger (MB2100-01) measures the execution cycle count or real-time between two events,
which the system has passed while a user program is running.
This emulator debugger has the following features for performance measurement.
• Measuring the execution cycle count or real-time required to carry out the event-to-event execution
• Measuring up to 65535 times, using an event-to-event measurement as one cycle
• The allowable number of intervals is only one if one interval is required between two events.
The following shows the performance measurement image.

■ Measurement Items
This emulator debugger has the following performance measurement items.
- 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".

Measuring count: Accumulates the number of times the system passes from event to event.
Average: Average value obtained by dividing the total number of execution cycle count or real-
time between two events by the number of measurement
Minimum: The minimum value of the number of execution cycles or real-time required to carry
out the event-to-event execution.
This is available only for products which are compatible with the maximum/
minimum measurement.
