the ARM9 has most of the relevant hardware integrated. The unknown
factor for me is to deal with Linux (which is required for the project).
Writing kernel driver (at DMA/interrupt level) is certainly doable, but
I fear the problems I could get with this approach since I am relatively
new to ARM-Linux. If things go well, I still can later remove the ARM7.
