Trace-based Profiling

Function Run-Time Statistics

Function run-time analysis

The calculation of all Statisic Functions is based on the contents of the trace buffer. The best results can be reached by using a big trace buffer or by using trace filters. func: total number of analyzed functions total: total measurement time time: total time within a function min: shortest time within a function max: longest time within a function avr: average time within a function count: number of function calls

The following additional calculation can be performed:


• called subfunctions can be excluded from the measurement
• the time spent in interrupts can be excluded from the measurement
• the maximum time a function was interrupted can be calculated
• hll interrupt routines can be analyzed separatly

Link Analysis

If a function was called serveral time, the linkage analysis shows
• the different callers
• a caller-dependent function run-time analysis

Statistics over Task Run-Times and States

Task Runtime Analysis

task: total number of analyzed tasks total: total measurement time time: total time within a task avr: average time within a task maxintr: maximum time the task was interrupted count: number of task calls ratio: fraction of the total time per task

Task Specific Function Analysis

func: total number of analyzed functions total: total measurement time time: total time within a function min: shortest time within a function max: longest time within a function avr: average time within a function count: number of function calls ratio: fraction of the total time per function

Task State Analysis (Graphical display)

Full black block: running Thick red line low: ready Small black line low: suspended Small black line low: waiting

Graphical Analysis of Variables Values over the Time

Graphical Analysis of the Value of a Single Variable

Various display formats are provided.

Graphical Analysis of the Values of up to 6 Variables

Each colour represents one variable.

Analysis of the Time Interval of a Single Event

samples: total number of analyzed samples avr: average interval min: smallest interval max: longest interval

16 time classes are automatically displayed. User-defined time classes are also possible.

Analysis of the Time Interval between 2 Defined Events

samples: total number of analyzed samples avr: average interval min: smallest interval max: longest interval

16 time classes are automatically displayed. User-defined time classes are also possible.
