INDEX MX86251 1.Introduction A graphics subsystem using the MX86251 and 3Dfx Interactive Voodoo RushTM combines industry leading 3D performance with the proven performance and compatibility of an industry standard 2D Windows accelerator. This union creates an extremely cost effective and uncompromising multimedia solution. The MX86251 provides 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 engines 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 enhancements to the base functionality. All processing engines 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 enhanced to 160 MHz to enab.
