Graphics Core
The internal graphics related logic in the GMCH. Also known as the Integrated Graphics
Device (IGD).
HI
Hub Interface. The proprietary hub interconnect that ties the GMCH to the ICH4. In this
document HI cycles originating from or destined for the primary PCI interface on the ICH4
are generally referred to as HI/PCI or simply HI cycles.
Host
Intel
ICH4
This term is used synonymously with processor or CPU.
Fourth generation I/O Controller Hub component.
IGD
Integrated Graphics Device. Graphics device integrated into the GMCH.
LVTTL
Low Voltage TTL 3.3 V (SDR).
Primary PCI
The physical PCI bus that is driven directly by the ICH4 component. Communication
between the PCI and the GMCH occurs over the hub interface. Note that even though the
Primary PCI bus is referred to as PCI, it is not PCI Bus #0 from a configuration standpoint.
PSB
Processor System Bus. This is the bus between the GMCH and processor (also referred
to as the Host, FSB, or processor bus).
Scalable Bus
Processor-to-GMCH interface. The Compatible Mode of the Scalable Bus is the P6 bus.
The Enhanced Mode of the Scalable Bus is the P6 Bus plus enhancements primarily
consisting of source synchronous transfers for address and data, and PSB interrupt
delivery. The Intel
Pentium 4 processor implements a subset of Enhanced Mode.
SDR
Single Data Rate SDRAM.
SDRAM
Synchronous Dynamic Random Access Memory.
Secondary PCI
The physical PCI interface that is a subset of the AGP bus driven directly by the GMCH. It
supports a subset of 32-bit, 66 MHz
PCI Local Bus Specification, Revision 2.1

components, but only at 1.5 V (not 3.3 V or 5 V).
SSTL_2
Stub Series Terminated Logic for 2.5 V (DDR).
