12.7.4 Run a coverage and profiling session
12.7.5 Run a performance analysis
The Performance analysis feature displays statistics on certain performance criteria
regarding the running of the application program. It measures the time spent in a section of
code, defined by its start and end addresses. Data such as the minimum execution time,
maximum execution time and the execution time as a percentage of the total overall
execution of all code is provided.
In this procedure you will learn how to use the Performance Analysis feature to measure the
time spent in a function (the trapISR function).
To run the performance analysis:
1. Select Debug Instrument>Performance Analysis.
2. In the Performance Analysis window enter 5 in the Number of passes field, check
the Disable breakpoints checkbox.
3. Select timer.c;69 and timer.c;97 from the Bookmarks fields for Starting Address
and Ending Address, respectively. These mark the first and last instruction of
trapISR function.
