What does XIO mean?

XIO
XIO is a packet-based, high-performance computer bus employed by the SGI Origin 2000, Octane, Altix, Fuel and Tezro machines. The XIO forms a bus between high-performance system devices and the memory controller. XIO is usually used in a star topology, using a router ASIC called Crossbow to connect up to eight fully symmetrical devices in a system. Other devices known to have XIO interfaces are: BRIDGE: XIO to PCI-64 bridge XBRIDGE: XIO to PCI-X bridge HQ4: command processor of ImpactSR cards KTOWN: frontend for InfiniteReality2 cards XC: Crosstown converter BUZZ: "OpenGL-on-a-Chip" ASIC used in ODYSSEY/VPro graphics The XIO employs two source-synchronous channels, each 8 or 16 bits wide. They are clocked at 400 MHz to achieve peak rates of 800 MB/s. Each of the devices can utilize the full bandwidth, as the XBow router prevents collisions by being able to route between any two points. Transfer is organized into micropackets. These contain a total of 128 bits of data and 32 bits of control. The control information encapsulates an 8 bit sideband, sequence numbers and check bits.
