Functional Description 35Graphics ControllerThe Volari™ Z11 graphics controller incorporates a powerful 64-bitgraphics engine to enhance the performance of 2D operations.The capabilities of the graphics engine include, but are not limitedto BitBlt, Color Expansion, Enhanced Color Expansion, Line Draw-ing, Transparent BitBlt, and Rectangle Fill.For all enhanced 256 color (8 bpp), 32k & 64k hi-color (16 bpp),and 16M true color (32 bpp) graphics modes, the 2D engine sup-ports the following functions:X 256 raster operationsX Rectangle fillX Color expansionX Enhanced Color expansionX Line drawing with styled patternX Built-in bytes pattern registersX Built-in 8x8 mask registersX Rectangle Clipping Transparent BitBlt with source and des-tination keysX Source data in command queue BitbltThe engine also supports new GDI 2000 functionsPCI Bus InterfaceThe Volari™ Z11 GPU is a native PCI-E device whichconnects directly to the PCI-E bus onboard the mother-board. The Z11 decodes 32-bit addresses and configures thedevice based on the applicable control lines between the targetand initiator. The GPU can execute both I/O and memoryaccess instructions as a 32-bit device.BroadBahn™ Memory ArchitectureThe internal memory controller of the Z11 generates the timingparameters for display memory. It supports the DDRII SDRAMtiming specificationsThe frequency of the Volari™ Z11 memory controller interfaceis synchronous with the 2D engine at 125MHz with the I/O
