desigen ARM board

Hi every body
I'm going to create a ARM board with these features:
1. ARM micro-controller (which supports WINCE)
2. A touch LCD
3. 2 sign LED
4. 4*4 keypad
5. USB (for install WINCE on ARM => or maybe another connector be used )

As you know the ARM frequency is around 2GHz and designing board in not
like AVR board.
Actually I don't know what is the designing deference between ARM board and
low frequency boards.
I was wondering if you help me.
Thanks

There is a great high speed design overview using Altium Designer that
might be useful for you.

If you have only done simple AVR board then a full blown high speed ARM on
multilayer (6 or 8) is going to be a challenge and you will need to learn
quite a lot.

I am looking to do this myself in the next few months and the above
document is very helpful.

Good luck with your project.
