[ For those not in the know: the IXP2400 is basically just an xscale (which is Intel's version of ARM) processor, with some extra on-chip processing logic for fast network processing. The chip itself has an integrated memory controller, 64b/66MHz PCI unit, 4Gbps SPI-3 bus, and 8 on-chip processors which have a very simple instruction set designed to do network-related things such as switching, routing, firewalling, etc. It can do full wire speed 4xGbps processing, and its bigger brother, the IXP2800, does full wire speed 10xGbps. ]
So how close is this processor to the older StrongArm processor used in the now orphaned Netwinder?
I don't think xscale code runs on the strongarm.
I'm not sure if strongarm code runs on the xscale -- can you send me a statically linked hello world binary to find out? (Is the strongarm mixed endian like the xscale?)
ARM is to XScale as 486 is to Pentium. (Strong)ARM code runs on XScale just fine.
I think ARM is typically LE, but it may be possible to run BE, I don't remember off the top of my head. I believe the Zaurus is LE.
