Functional Description 35
Graphics Controller
The Volari™ Z11 graphics controller incorporates a powerful 64-bit
graphics engine to enhance the performance of 2D operations.
The capabilities of the graphics engine include, but are not limited
to 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 operations
X
Rectangle fill
X
Color expansion
X
Enhanced Color expansion
X
Line drawing with styled pattern
X
Built-in bytes pattern registers
X
Built-in 8x8 mask registers
X
Rectangle Clipping Transparent BitBlt with source and des-
tination keys
X
Source data in command queue Bitblt
The engine also supports new GDI 2000 functions
PCI Bus Interface
The Volari™ Z11 GPU is a native PCI-E device which
connects directly to the PCI-E bus onboard the mother-
board. The Z11 decodes 32-bit addresses and configures the
device based on the applicable control lines between the target
and initiator. The GPU can execute both I/O and memory
access instructions as a 32-bit device.
BroadBahn™ Memory Architecture
The internal memory controller of the Z11 generates the timing
parameters for display memory. It supports the DDRII SDRAM
timing specifications
The frequency of the Volari™ Z11 memory controller interface
is synchronous with the 2D engine at 125MHz with the I/O
