Motherboard Description

1.9.1S3 ViRGE Graphics Subsystem

The AP440FX motherboard is available with a factory option of an S3 ViRGE SVGA graphics controller with 2 MB of 50 ns EDO SOJ DRAM. The S3 ViRGE has a high performance 64-bit 2D/3D graphics engine and incorporates the S3 Streams Processor that enables the device to convert YUV formatted video data to RGB and provides acceleration for scaling the video display without compromising picture quality or frame rate. The on-chip RAMDAC/clock synthesizer is capable of output pixel data rates of 135 MHz providing non-interlaced screen resolutions of up to 1280x1024x256 colors at 75 Hz. The 64-bit S3d Engine incorporates the key Windows and other GUI accelerator functions of BitBLT, line draw and polygon fill. 3D features include flat shading, Gouraud shading and texture mapping support. Advanced texture mapping features include perspective correction, bi-linear and tri-linear filtering, MIP-mapping, and Z-buffering. These features provide the most realistic user experience for interactive 3D applications. In addition, a fast linear addressing scheme based upon DCI reduces software overhead by mapping the display memory into the microprocessor’s upper memory address space and permitting direct microprocessor access to the display memory.
