Remarks to the benchmark software
---------------------------------

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.
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).

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.


Hinweise zum Benchmark Programm
-------------------------------

Das Benchmark-Programm dient zur Messung der CPU-Performance. Dabei werden
Testroutinen verwendet, welche typisch sind f黵 die bei uns vorkommenden
Anwendungen im Embedded-Bereich (Feldbus-Controller).
Der Fokus der Tests liegt hierbei beim Interrupt-gesteuerten Filtern, 
Formatieren und Weiterreichen von kurzen Nachrichten.
Hierzu werden Laufzeittests 黚er mehrere Routinen aus diesem Anwendungsbereich
durchgef黨rt, welche zusammen einen Performance-Faktor ergeben.
Dieser Wert wurde f黵 unsere Standard-Plattform so normiert, so da
