The benchmark software is used to determine the CPU performance. It uses test
routines which are typically for embedded applications with field bus controllers.
The focus of the test are the interrupt controlled filter functions, formatting
and forwarding of short messages.
<o:p></o:p></span></p>
<p><span lang=EN-GB style='font-size:10.0pt;mso-ansi-language:EN-GB'>
The performance factor is determined by executing run-time tests with several routines
for these applications.
IXXAT provides reference value 100.0 which has been achieved with the standard platform,
the iPCI-I165 (see also result.txt).
<o:p></o:p></span></p>
<p><span lang=EN-GB style='font-size:10.0pt;mso-ansi-language:EN-GB'>

The tests are based on the following assumptions regarding the platform/CPU:
- Usage of the RS232 interface for the output of test steps and test results
- A timer resolution of 1ms as time base for all tests. The timer interrupt routine has
  to have a higher priority as the measurement routine which is also been used.
- An interrupt request which can be activated by software and which activates the
  measurement interrupt routine. If this interrupt request cannot be activated directly
  on the CPU, a interrupt port pin or something similar has to be used. This measuerement
  interrupt routine has to be interruptable by the timer interrupt routine.

Functions which are CPU/platform dependent are summarize in the file CPUxxx.c. The file
benchmrk.c and target.h shall therefore not be modified, if possible.
