What is "xorro"

Xorro is a new slot using an industry standard PCIe ×8 form factor to give access to the ' Xena' I/O. This will be the route to Xena's 64 I/O lines, which are dynamically configurable as input, output, or bidirectional. 'Xorro' will allow bridging Xena to external hardware for control purposes, to internal systems, or to other XCore processors. This last point is worth more exploration; XCore is a parallel processing architecture, and if you want more power, you can simply chain more XCores together (XK-XMP-64 Development Board). Reference boards have been made with up to 256 cores, offering a theoretical 102400 MIPS.
