Table 1. Glossary of Terms and Acronyms (Sheet 1 of 3)
Term Description
ADD2 Card
Advanced Digital Display Card – second Generation. This card provides digital display
options for an Intel Graphics Controller. It plugs into an x16 PCI Express* connector but
uses the multiplexed SDVO interface. This Advanced Digital Display Card will not work
with an Intel Graphics Controller that supports DVO and ADD cards.
ACPI Advanced Configuration and Power Interface
ASF Alert Standard Format
BLT Block Level Transfer
Core The internal base logic in the (G)MCH
CRT Cathode Ray Tube
DBI Dynamic Bus Inversion
DDR2 A second generation Double Data Rate SDRAM memory technology.
DMI Direct Media Interface
DVI
Digital Video Interface. Specification that defines the connector and interface for digital
displays.
FSB Front Side Bus. FSB is synonymous with Host or processor bus.
Full Reset
Full reset is when PWROK is de-asserted. Warm reset is when both RSTIN# and PWROK
are asserted.
GMCH
Graphics Memory Controller Hub component that contains the processor interface, DRAM
controller, x16 PCI Express* Graphics port (typically, the external graphics interface), and
integrated graphics device (IGD). It communicates with the I/O controller hub (ICH8DO*)
and other I/O controller hubs over the DMI interconnect. In this document GMCH refers
to the 82Q965 GMCH component.
GMA 3000 Intel® Graphic Media Accelerator 3000
Host This term is used synonymously with processor.
IDER IDE Redirect
INTx An interrupt request signal where “x” stands for interrupts A, B, C, and D
Intel® 64

(Formerly known as Intel® EM64T) enables the processor to
access larger amounts of virtual and physical memory.
Intel® Advanced
Digital Media
Boost
128-bit SSE instructions are now issued one per clock cycle effectively doubling their
speed of execution over previous generation processors. This benefits a broad range of
applications including video, audio, encryption, engineering and scientific with improved
performance.

Active Management Technology
Intel® Advanced
Smart Cache
The shared L2 cache is allocated to each processor core based on workload up to the full
amount of total cache. This is more efficient than today’s dual-core processor. Sharing the
cache significantly reduces the time needed to retrieve frequently used data improving
performance.
Intel® DVO
Digital Video Out port. Term used for the first generation of Intel Graphics Controller’s
digital display channels. Digital display data is provided in a parallel format. This interface
is not electrically compatible with the 2
nd
generation digital display channel discussed in
this document – SDVO.
Intel® ICH8DO
Eighth generation I/O Controller Hub component that contains additional functionality
compared to previous ICHs. The I/O Controller Hub component contains the primary PCI
interface, LPC interface, USB2, SATA, and other I/O functions. It communicates with the
(G)MCH over a proprietary interconnect called DMI.

Quiet System Technology
Intel® Smart
Memory Access
Optimizes functions for reducing wait time, moving data and accelerating out-of-order
execution, keep the pipeline full improving instruction throughput and performance.
