Enable Timestamping
Select Enable Timestamping to enable the timestamp-recording logic in the trace capture hardware. Timestamps are displayed in the Time/unit and +Time columns of the Analysis window. You can change the format in which timestamps are displayed using the Scale Time Units option in the View menu. Analyzing timestamp values enables you to see, for example, when pauses have occurred in processor execution, and how long it takes between successive invocations of a particular section of code.
If
you want to view profiling statistics, you must enable either timestamping,
or cycle accurate tracing, or both. The best results are obtained when
both options are enabled.
Not all types of trace capture hardware support this feature. Refer to
your hardware documentation for more information.
Transmitting
the timestamps
uses noticeable additional bandwidth on the trace capture hardware to
host connection. Storing the timestamps
in the trace capture hardware might reduce the maximum length of trace
that you can capture. You should therefore only enable this feature when
you have to.
