Performance Analyzer

The Performance Analyzer shows execution statistics, like time and number of calls of a function or module.

Performance Analyzer for ARM Architectures

For ARM processor-based devices, statistics are collected for the complete program code. The Performance Analyzer displays the information collected by the Execution Profiler for known address ranges. This means, the list does not include information for address ranges without debug information, such as the floating point library of the ARM RealView toolset.

Results are displayed as bar graphs, along with call and time information. The list sorts itself automatically after a few seconds. Thus, the most time consuming modules or functions are displayed at the top of the list.

Performance Analyzer Example Display

A context menu can be invoked by clicking the right mouse button. This menu offers the possibility to switch between the modules/functions representation of the statistics. Also, the collected statistics can be cleared from here.

Double-click a function name to jump right to the code of that function.

Label	Description
Reset	Button that clears recorded statistics.
Show: drop-down list	Selector to display statistics grouped by modules or functions.
Module/Function	The name of the module or function.
Calls	The number of calls to a function.
Time(Sec)	The total time spent in the address range of the function or module.
Time(%)	The percent of the total time spent in the selected address range or function.

Performance Analyzer for 8051, 251, or 166 Architectures

For the 8051, 251, or 166 architectures, the Performance Analyzer has to be configured using the Setup... button or the PA command in the Command Window. Specify the functions or address ranges for recording data.

Performance Analyzer

Results are displayed as bar graphs. Statistics, such as invocation count, minimum time, maximum time, and average time, are displayed for the specified function or address range.

The <unspecified> address range is generated automatically. It shows the time spent executing code that is not included in the specified functions or address ranges.

Label	Description
min time	The minimum time spent in the selected address range or function.
max time	The maximum time spent in the selected address range or function.
avg time	The average time spent in the selected address range or function.
total time	The total time spent in the selected address range or function.
%	The percent of the total time spent in the selected address range or function.
count	The total number of times the selected address range or function was executed.
