1.6.2Intel 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
