Chipsets for Embedded Computing
Product Overview
The Intel® 945G Express and Intel® 945GC Express chipsets deliver
innovative features for interactive clients and many other embed-
ded computing solutions requiring enhanced graphics capabilities.
These advancements include dual-channel DDR2-667 memory
technology, Intel® Graphics Media Accelerator 950 (Intel® GMA
950), enhanced manageability and storage security technologies
with Intel® Active Management Technology¹ (Intel® AMT), and Intel®
Matrix Storage Technology.
Designed for, and validated with Intel® Pentium® 4 processors 551^∆
and 651^∆ with Hyper-Threading Technology² (HT Technology), and
Intel® Celeron® D processors 352^∆ and 341^∆ — all with Intel® 64
Architecture³ — these platforms provide scalable performance
and are ideal price/performance solutions for embedded
computing applications.
These chipsets consist of a Graphics and Memory Controller Hub
(GMCH) and Intel® ICH7/ ICH7R I/O Controller Hub (ICH). They deliver
outstanding system performance through high-bandwidth inter-
faces such as PCI Express* x16 graphics or I/O, PCI Express x1 I/O
ports, next-generation Serial ATA (SATA II), and Hi-Speed USB 2.0
connectivity.
The new graphics core, combined with a high-performance
dual-channel memory interface, can deliver significant graphics
performance over previous Intel® platforms. With support for
dual independent display, enhanced modes for widescreen flat
panels, and optimized 3D, embedded platforms based on the
Intel 945G Express or Intel 945GC Express chipset can deliver
an intense, realistic visual experience without requiring a
separate graphics card.
Product Highlights
• 533/800/1066 MHz system bus on the Intel 945G Express
chipset, and 533/800 MHz system bus on the Intel 945GC
Express chipset provide scalability to higher performance
Intel Pentium 4 processors with HT Technology and Intel
Celeron D processors
• Dual-channel DDR2-400/533/667 delivers up to 10.7 GB/second
of bandwidth and 4 GB memory addressability for faster system
responsiveness and support for 64-bit computing
• Intel® Flex Memory Technology facilitates easier upgrades by
allowing different memory sizes to be populated and remain
in dual-channel mode
• Dual independent display support through the integrated Intel
GMA 950 graphics engine and sDVO outputs
• PCI Express x16 GFx can deliver up to greater than 3.5 times the
bandwidth of previous discrete graphics solutions; PCI Express
x16 interface can also operate as x1 general-purpose I/O
• Both ADD2 and Media Expansion Cards (MECs) allow users to take
advantage of several video output options (DVI, dual independent
display, component, composite, HDTV, and LVDS) in a single-card
solution. In addition, MECs enable video input capability and personal
video recorder (PVR) functionality, and can support a wide range of
display types and configurations.
• Intel Matrix Storage Technology provides protection and faster
access to digital photo, video, and data content through RAID 0, 1,
5, and 10
• Advanced Host Controller Interface⁴ provides native command
queuing for faster boot time and file transfers
• Direct Media Interface (DMI) delivers 2.0 GB/second concurrent
bandwidth to maximize throughput between the core chipset
components
• Six PCI masters provide generous system expansion capability
• ICH7 supports up to four PCI Express ports configurable as one
single x4 or four single x1
