Hmmm.. that could be interesting; I'd like more information when it becomes
available. The real reason I ask, is because I'm curious about exploring
some efficient, low-cost architectures for one of our products at work.
Our current systems use embedded Intel architecture (chipset and UP
Pentium-class CPU on standard PCI bus). I enquired about StrongARM because
the low-cost, low power-consumption makes it ideal for a processor driving
small network appliances. The question about SMP came because I was
thinking that having two modest-paced processors for this kind of
application beats out a single fast processor, because you can be servicing
interrupts and bh's without starving user-space (this isn't a flawed
understanding of 2.2 SMP, is it? That one processor can be executing a bh
in the kernel while the other is executing on behalf of a user-space
process?)
Thanks everyone for the very helpful answers; I'm not on this list and I
appreciate the cc'd responses. :-)
cheers,
