Intel Direct Media Interface (DMI)
The DMI (previously called the Enterprise Southbridge Interface) connects the Tylersburg IOH with the
Intel I/O Controller Hub (ICH). The DMI is equivalent to a x4 PCIe Gen1 link with a transfer rate of 1 Gb/s
in each direction.
PCI Express Generation 2
PCI Express is a serial point-to-point interconnect for I/O devices. PCIe Gen2 doubles the signaling bit
rateofeachlanefrom2.5Gb/sto5Gb/s.EachofthePCIeGen2portsarebackwards-compatiblewith
Gen1 transfer rates.
In the Tylersburg-36D IOH, there are two x2 PCIe Gen2 ports (1Gb/s) and eight x4 PCIe Gen2 ports (2
Gb/s). The x2 ports can be combined as a x4 link; however, this x4 link cannot be combined with any of
the other x4 ports. Two neighboring x4 ports can be combined as a x8 link, and both resulting x8 links
can combine to form a x16 link.
