Hi!
I've made a program to count the cortex A8 cycles.
For the moment this is just a beta version. It miss a lot of function.
Feel free to test it.
It will help me to find missing parsing rules.
You can return me any error in countig cycle process.
you can test it here.

This is in French, but I suppose google traduction should do the job.

hum!
I'm not sure to really understand the question.
Why the Cortex A8 ?
- because this is quite impossible with the cortex A9 (due to out of order Cortex A9 execution)
- because I've a beagleboard
Why count the cycle ?
- because this is the only way to really optimise an assembler function. The script can find bubble in the pipelines.
Why assembler ?
- because gcc is not very good to optimise ARM c code.
