Motherboard Description
SY-7ISA+
11
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
