1.6.2 Intel NQ82915GM and FW82801FMB ICH6-M
The Mobile Intel® 915GM Express Chipset for Embedded Computing, consisting of the
Intel® 915GM Graphic Memory Controller Hub (GMCH) and Intel® I/O Controller Hub 6-M
(ICH6-M), is an optimized integrated graphics solution with a 400 MHz and 533 MHz
front-side bus. The integrated 32-bit 3D graphics engine, based on Intel® Graphics Media
Accelerator 900 (Intel® GMA 900) architecture, operates at core speeds of up to 320 MHz.
It features a lowpower design, is validated with the Intel® Pentium® M and Intel® Celeron®
M processors on 90nm process, and supports up to 2 GB system memory.
Intel’s platform architecture delivers the performance and high scalability required for
today’s cutting-edge embedded computing applications. The Intel 915GM GMCH and
ICH6-M are part of Intel’s comprehensive validation process that enables fast deployment
of next-generation platforms to maximize competitive advantage while minimizing
development risks.
Intel 915GM chipset adds enhancements for the following areas:
• System Memory
• PCI Express Based Graphics (discrete graphics devices)
• Intel Graphics enhancements:
• DVMT 3.0 support
• Zone Rendering 2.0 support
• Quad pixel pipe rendering engine
• Pixel Shader 2.0 support
• 4x Faster Setup Engine
• TV Out Support
• HDTV resolution support
• LVDS support
• Wide panel support
• Ambient Light Sense support for automatic backlight brightness adjustments
• Intel Display Power Savings Technology 2.0 support
• Integrated PWM interface for LCD Backlight Inverter Control
• Direct Media Interface (DMI)
The GMCH integrates a system memory DDR controller with two, 64-bit wide interfaces.
Only double Data Rate (DDR) memory is supported; consequently, the buffers support
DDR SSTL_2 signaling interfaces. The memory controller interface is fully configurable
through a set of control registers.
Three system memory modes of operation supported are:
• Single Channel mode
• Dual Channel Asymmetric mode
• Dual Channel Symmetric mode
