The xmos is no custom chip.Its a mass ware that is not only available in the X1000

A custom Chip is more common called as a ASIC

http://en.wikipedia.org/wiki/ASIC

The sense of the xmos in the X1000 mainboard i cant understand.I read in the docu and as far i can see when use maximum of 5 wires the Chip can transfer max 800 megabit /Sec.
(page 9/26)

So this make in best case a Interconnect rate of 100 megabyte/sec.Thats little slower as a PCI and USB3 is fast enough to connect the Chips.

But the transfer speed of the xmos is way too few to do some acceleration, because even a slow PPC CPU as the SAM can load and store data at 250 Megabyte /Sec

also when somebody want use the XMOS, he need a controller card that offer the IO.Maybe this should put in the Xorro Slot.

But when this should put in the Xorro slot the xmos Xhip can also put on the Card.this make the X1000 little cheaper and need little less power.
