1-6.5.2  AIMM Card Interface 
Display Cache Interface multiplexed on the AGP interface: 
 
32-bit data interface 
 
133 MHz SDRAM interface only 
 
Flexible AGP In-Line Memory Module (AIMM) 
Implementation 
 
Support for 2 1Mx16, or 1 2Mx32 on AIMM card 
 
4MB max addressable 
1-6.5.3  Display Cache Interface 
The Intel® 815E GMCH support a Display Cache SDRAM 
controller with a 32-bit 133 MHz SDRAM array. The DRAM type 
supported is industry standard Synchronous DRAM (SDRAM) like 
that of the system memory. The local memory SDRAM controller 
interface is fully configurable through a set of control registers. 
1-6.6 Hub Interface 
The hub interface is a private interconnect between the Intel® 815E 
GMCH and the ICH2.   
1-6.7  Intel® 815E GMCH Integrated Graphics Support 
The Intel® 815E 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 Intel® 
815E 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
