Product Description

The S3 ViRGE/GX2 integrated 3D video/graphics accelerator enables compelling interactive entertainment, education, and presentation applications for the mainstream personal computing world.

Enhancements to the Popular ViRGE/DX & GX Accelerators

Synchronous memory support up to 83 MHz Baseline AGP support with 66 MHz PCI bus TV output support with: Integrated NTSC/PAL encoder 3-tap flicker filter Underscan compensation DuoView^TM dual-display output to a TV and PC monitor 24-bit digital YUV port for connection to Macrovision and video processors

64-bit S3d Engine

The enhanced S3d Engine provides improved 2D acceleration for excellent Windows applications performance and a full-featured high-performance 3D rendering engine for realistic user experience in games and other interactive 3D applications.

Streams Processor

The S3 Streams Processor technology provides the stretching and YUV color space conversion features required for full screen video playback with both software CODECs and hardware MPEG sources. It allows simultaneous display of graphics and video of different color depths. This saves memory bandwidth and storage capacity while permitting higher frame rates. The ViRGE/GX2 Streams Processor supports enhanced features such as vertical interpolation and color controls for high quality video playback.

S3 Scenic Highway

The S3 Scenic Highway allows low cost connection to industry-standard MPEG decoders and video digitizers.

AGP/PCI Bus Support

ViRGE/GX2 supports 66 MHz AGP DMA mode for the highest possible 3D rendering performance. By bus mastering texture data at over twice the speed of conventional PCI buses, AGP DMA reduces the amount of CPU overhead while improving 3D rendering performance. PCI bus master support maximizes video capture performance.

TV Output Support

The integrated TV encoder enables TV outputs of NTSC/PAL composite or S-video signals, providing flexibility for desktop computers. The 3-tap flicker filter used in the conversion of non-interlaced format to interlaced format as well as underscan compensation ensure excellent TV output quality.
