Introduction
Term
Description
A unit of DRAM corresponding to number of SDRAM devices in parallel such
that a full 64-bit data bus is formed.
Rank
Intel® System Controller Hub: a single-chip component that contains the
processor interface, DDR2 SDRAM controller, Intel Graphics Media Accelerator
500 (Intel® GMA 500), various display interfaces, USB, SDIO, PCI Express*,
PATA, LPC, and other I/O capabilities.
Intel® SCH
SCI
System Control Interrupt. SCI is used in the ACPI protocol.
Serial Digital Video Out (SDVO). SDVO is a digital display channel that serially
transmits digital display data to an external SDVO device. The SDVO device
accepts this serialized format and then translates the data into the appropriate
display format (i.e., TMDS, LVDS, TV-Out).
SDVO
Third-party codec that use SDVO as an input may have a variety of output
formats, including DVI, LVDS, HDMI, TV-Out, etc.
SDVO Device
SERR
System Error. SERR is an indication that an unrecoverable error has occurred
on an I/O bus.
System Management Interrupt. SMI is used to indicate any of several system
conditions (such as thermal sensor events, throttling activated, access to
System Management RAM, chassis open, or other system state-related
activity).
SMI
Transition Minimized Differential Signaling. TMDS is a signaling interface from
Silicon Image that is used in DVI and HDMI. TMDS is based on low-voltage
differential signaling and converts an 8-bit signal into a 10-bit transition-
minimized and DC-balanced signal (equal number of 0’s and 1’s) in order to
reduce EMI generation and improve reliability.
TMDS
Top of Low Memory. The highest address below 4 GB where a processor-
initiated memory read or write transaction will create a corresponding cycle to
DRAM on the memory interface.
TOLM
UHCI
Universal Host Controller Interface. A controller interface that supports two
USB 1.1 ports. The Intel® SCH contains three UHCI controllers.
Unified Memory Architecture. UMA describes an Intel Graphics Media Adapter
using system memory for its frame buffers.

VCO
Voltage Controlled Oscillator
