Profiling and Optimization

Execution profiling, display, analysis, and optimization by using MATLAB^® functions

Profile the task execution time and function execution time of the real-time application that is running on the target computer. Then, you can tune its performance.

Objects

`Target`	Represent real-time application and target computer status
`Instrument`	Create real-time instrument object
`slrealtime.instrument.LineStyle`	Create real-time instrument LineStyle object
`ProfilerData`	Data returned from profiler
`Stimulation`	Target computer model root inport stimulator object

Functions

`startProfiler`	Start profiling service on target computer
`stopProfiler`	Stop profiling service on target computer
`getProfilerData`	Retrieve profile data object
`resetProfiler`	Reset profiling service state to `Ready`
`slrtTETMonitor`	Open Simulink Real-Time task execution time (TET) monitor
`plot`	Generate execution profiler plot
`report`	Generate profiler report
`getSupportInfo`	Creates `slrealtimeinfo.txt` file that provides information about Simulink Real-Time installation
`getCrashStack`	Downloads and decodes core files from target computer and opens these in MATLAB editor

Blocks

Enable Profiler	Start and stop execution profiler on target computer
Log Event	Log an execution profiling event
