82815 GMCH Integrated Graphics Support
The 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 which 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, trilinear and
anisotropic Mip-Map filtering, 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 GMCH, a Display Cache (DC) can be used for the Z-buffer (textures and display buffer(s) are
located only 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 which may support (via an external video encoder) NTSC
and PAL broadcast standards and (via an external TMDS transmitter) digital Flat Panel or Digital CRT
displays.

Display, Digital Video Out, and LCD/Flat Panel/Digital CRT
The GMCH provides interfaces to a standard progressive scan monitor, TV-Out device, and TMDS
transmitter. These interfaces are only active when running in internal graphics mode.
The GMCH directly drives a standard progressive scan monitor up to a resolution of 1600x1200
pixels.
The GMCH provides a Digital Video Out interface to connect an external device to drive a
1280x1024 resolution non-scalar DDP digital Flat Panel with appropriate EDID 1.2 data or digital
CRTs. 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.
