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.

Maximum:

The maximum 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.
