I am developing an embedded app that must receive a 128 byte message every 100 microseconds. It must reply with a 128 byte message within 100 us of receiving it's message (i.e. before the next message comes in). So I need bandwidth of 10,240,000 bits/second.
Does anyone know of any PCI cards that can support these speeds?
I have tried to do this with TCP/IP over ethernet, but was unable to maintain the needed speeds. I've also tried UDP, also without success. I've looked at some USB host-host devices, but I haven't found any that support these speeds and allow me to programmatically control them. Firewire isn't supported by my RTOS, so that's out. So now I'm thinking LVDS or some other high speed serial device, but I'm not having any luck finding applicable products. Anyone??
TIA!
