Execution transition status display window
The tools supported for this analyzer and their operating environments are shown in the table below.
The performance analyzer consists of four windows:
Trace display window
Trace display window
Execution transition status display window
CPU utilization rate display window
Processing time pattern distribution display window
This window displays the object movement versus time relationship, with time indicated by the horizontal
axis and object movement by the vertical axis. Analysis of system status changes caused by task switching
or interrupts/exceptions, and object accesses based on real-time OS system calls are displayed as symbols,
making it easy for the user to ascertain the sequence and transition of execution. These functions enable
specification of the problems for the performance analysis.
This window can be used to confirm the object execution time and CPU utilization rate that guide users in the
analysis of the system overhead and indicate execution performance, so that the system performance can
be evaluated from the view point of the idle time and interrupt time.
Users can analyze the causes of scheduling problems by viewing the statistical breakdown of the execution
processing time, as well as the interrupt frequency and execution time maximum/average/minimum figures
displayed in this window.
Trace data from the execution transition status can be viewed. This window can be used as a sub window of
the execution transition status window so that timestamps of execution status transitions and values re-
turned by system calls can be checked.
Note Some functions can also be executed using a partner debugger.
