if you realy need very high sampling or realtime processing rates
you might consider using an SMP X86 with a dedicated CPU running
your high-speed RT-task - scheduling of tasks at 400KHz on a
400MHz PIII SMP are "posible" but don't expect much time to do
anything sensible this is "switching for the fun of it" , if
your demands are below that you might consider an SMP solution.
