GMCH Graphics Support
The Graphics and Memory Controller Hub (GMCH) includes a highly integrated graphics accelerator. Its
architecture consists of dedicated multi-media engines executing in parallel to deliver high performance
3D, 2D and motion compensation video capabilities. The 3D and 2D engines are managed by a 3D/2D
pipeline preprocessor allowing a sustained flow of graphics data to be rendered and displayed. The
deeply pipelined 3D accelerator engine provides 3D graphics quality and performance via per-pixel 3D
rendering and parallel data paths that allow each pipeline stage to simultaneously operate on different
primitives or portions of the same primitive. The GMCH graphics accelerator engine supports
perspective-correct texture mapping, bilinear and anisotropic Mip-Mapping, Gouraud shading, alpha-
blending, fogging and Z-buffering. A rich set of 3D instructions permit these features to be independently
enabled or disabled.
For the 82810E, a Display Cache (DC) can be used for Z-buffers (Textures and display buffer are located
in system memory). If the display cache is not used, the Z-buffer is located in system memory.
The GMCH integrated graphics accelerator’s 2D capabilities include BLT and arithmetic STRBLT
engines, a hardware cursor and an extensive set of 2D registers and instructions. The high performance
64-bit BitBLT engine provides hardware acceleration for many common Windows operations.
In addition to its 2D/3D capabilities, the GMCH integrated graphics accelerator also supports full
MPEG-2 motion compensation for software-assisted DVD video playback, a VESA DDC2B compliant
display interface and a digital video out port that may support (via an external video encoder) NTSC and
PAL broadcast standards.
The GMCH provides interfaces to a standard progressive scan monitor, TV-Out device, and LCD/Flat
Panel transmitter.
• The GMCH directly drives a standard progressive scan monitor up to a resolution of 1600x1200.
• The GMCH provides a Digital Video Out interface to connect an external device to drive an
autodetection of 1024x768 non-scalar DDP digital Flat Panel with appropriate EDID 1.x data.
The interface has 1.8V signaling to allow it to operate at higher frequencies. This interface can also
connect to a 1.8V TV-Out encoder.
