3d Graphic Chipset - Macronix International

A graphics subsystem using the MX86251 and 3Dfx In- teractive Voodoo RushTM combines industry leading 3D performance with the proven performance and compat- ibility of an industry standard 2D Windows accelerator. This union creates an extremely cost effective and un- compromising Multimedia solution. The MX86251 pro- vides a PCI system Interface and high performance VGA, 2D, and Video features in a low cost 2D chip while the Voodoo RushTM delivers 3D graphics processing power. The MX86251 connects to Voodoo RushTM through the high performance 64-bit VR Interface The VR Interface supports the render/refresh operation of the 2D/3D en- gines and the system control of the 3D devices. The MX86251 supports not only the basic Double Buffer Scheme, but also Triple and Quad Buffer swap for super smooth animation and 3D stereo glasses applications. The STATUS signal provides 3D status to the PCI host through the MX86251. The MX86251 is based on proven MX86250 2D Video window accelerator technology, while adding many en- hancements to the base functionality. All processing en- gines on the chip are running on a faster Clock up to 75 MHz which means 600 MB/sec peak memory bandwidth. Higher bandwidth means higher 2D performance and higher frame rate Video The Linear Frame Buffer write cycle from the PCI bus is now executed in one Clock cycle. That is, the CPU now has much greater write bandwidth into frame Buffer memory. The on chip RAMDAC is en- hanced to 160 MHz to enable many high resolution Video modes. Contrast and Brightness adjustments are added to the Video Processor so that dark MPEG-1 Videos will look much better on the screen. ALL these features of the MX86251 combines to make a powerful graphics experience for Multimedia By Macronix International Co.
