PCI Devices and Functions
NOTES:
1.
The following sub-sections provide an overview of ICH8 capabilities.
Direct Media Interface (DMI)
Direct Media Interface (DMI) is the chip-to-chip connection between the Memory
Controller Hub / Graphics Memory Controller Hub ((G)MCH) and I/O Controller Hub 8
(ICH8). This high-speed interface integrates advanced priority-based servicing allowing
for concurrent traffic and true isochronous transfer capabilities. Base functionality is
completely software-transparent, permitting current and legacy software to operate
normally.
PCI Express* Interface
The ICH8 provides up to 6 PCI Express Root Ports, supporting the PCI Express Base
Specification, Revision 1.1. Each Root Port supports 2.5 Gb/s bandwidth in each
direction (5 Gb/s concurrent). PCI Express Root Ports 1–4 can be statically configured
as four x1 Ports or ganged together to form one x4 port. Ports 5 and 6 can only be used
as two x1 ports. On Mobile platforms, PCI Express Ports 1–4 can also be configured as
one x2 port (using ports 1 and 2) with ports 3 and 4 configured as x1 ports.
