I'm considering a device using Linux as an OS.
It should consist of a custom PCB and a third party CPU PCB. This design was chosen because using a CPU chip directly would force a redesign when the particular chip will not be available any more. So an "industry standard" bus system should be used to interface the custom PCB with the CPU. Unfortunately the I/O performance needed exceeds what ISA bus could offer. So PCI (or whatever) must be chosen.
An obvious choice would be PC/104 plus, but those CPU cards tend to be very expensive.
Another idea is USB 2.x or Firewire. No idea about small CPU cards that offer one of those.
Can anybody offer any additional suggestions ?
Thanks, Michael
