S3 Trio 3D/2X Multimedia Accelerator

Overview

The S3^® Trio3D/2X integrated graphics/video accelerator combines high-performance graphics and high-quality video acceleration. Designed to meet the needs of tomorrow's productivity applications, S3's Trio3D/2X features a 2D graphics engine that delivers a high level of 2D graphics performance for the mainstream PC market. Key features of the Trio3D's 2D engine include a 128-bit pipelined architecture, support for 100MHz SGRAM memory and S3's Burst Command Interface - a proprietary protocol technology that works in conjunction with either the PCI or AGP bus to increase the command and data efficiency of the Trio3D/2X architecture. With features such as high-quality video manipulation (blending/stretching/scaling) and the ability to simultaneously accelerate dual video windows, S3's Trio3D/2X provides an optimal hardware platform for advanced video conferencing and video training applications on mainstream business PCs. Trio3D/2X's "business-ready" 3D feature set delivers the right mix of 3D performance and quality needed for emerging mainstream 3D productivity applications. Based on S3's widely adopted S3d architecture, the Trio3D/2X's rendering features include MIP mapping, tri-linear filtering and perspective correction of textures to deliver images that are free of visual artifacts such as "sparkle" and "jaggies." Other features include transparency for enabling realistic rendering of glass, water and plastic objects; depth cueing to enable the rendering of real-world environments; and Z-buffering to speed the removal of hidden surfaces for improved performance and visual quality.
