Core Components and Technologies AGP Graphics Controllers SiS Super AGP Graphics (VEi 7 PCs) SiS super AGP graphics is an integrated 3D graphics system built in to the SiS 620 chip. Super AGP has the following features: Integrated 2D Accelerator The integrated 2D accelerator is a 64-bit BITBLT graphics engine. It supports all 256 raster operations and DirectDraw. The accelerated primitives include: BLT, Transparent BLT, Color expansion, Clipping, Multiple scanline, Polylines, Patterns, Trapezoid Fills. Up to 8MB of frame buffer can be used with linear addressing. Integrated 3D Accelerator The integrated 3D graphics accelerator is composed of the triangle setup engine and the rendering engine. The hardware acceleration features can be enabled by the SiS driver under Direct 3D and OpenGL. Supported 3D quality acceleration includes: Gouraud Shading, Z buffer, Alpha buffer, Perspective Correction, MipMapping, Tri-linear Texture Filtering, Specular Lighting and Dithering. Integrated Graphics Accelerator The integrated graphics accelerator is compatible with AGP1.0 and PCI 2.2 configurations. Display memory can be up to 8MB of SGRAM. The super AGP architecture provides a bandwidth of 800MB/s between VGA and the host bus, an increase of 50% compared with AGP 2X mode (532MB/s). The display memory interface bus frequency can also be operated at up to 100MHz, with a 64-bit data path. 29

SiS Super AGP Graphics (VEi 7 PCs)
SiS super AGP graphics is an integrated 3D graphics system built in to
the SiS 620 chip. Super AGP has the following features:
Integrated 2D
Accelerator
The integrated 2D accelerator is a 64-bit BITBLT graphics engine. It
supports all 256 raster operations and DirectDraw. The accelerated
primitives include: BLT, Transparent BLT, Color expansion, Clipping,
Multiple scanline, Polylines, Patterns, Trapezoid Fills. Up to 8MB of
frame buffer can be used with linear addressing.
Integrated 3D
Accelerator
The integrated 3D graphics accelerator is composed of the triangle
setup engine and the rendering engine. The hardware acceleration
features can be enabled by the SiS driver under Direct 3D and OpenGL.
Supported 3D quality acceleration includes: Gouraud Shading, Z buffer,
Alpha buffer, Perspective Correction, MipMapping, Tri-linear Texture
Filtering, Specular Lighting and Dithering.
Integrated Graphics
Accelerator
The integrated graphics accelerator is compatible with AGP1.0 and PCI
2.2 configurations. Display memory can be up to 8MB of SGRAM.
The super AGP architecture provides a bandwidth of 800MB/s between
VGA and the host bus, an increase of 50% compared with AGP 2X
mode (532MB/s). The display memory interface bus frequency can also
be operated at up to 100MHz, with a 64-bit data path.
