5.19.1 2D Graphics Engine
The Volari Z11M 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 Drawing,
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 supports the following functions:
 256 raster operations
 Rectangle fill
 Color expansion
 Enhanced Color expansion
 Line drawing with styled pattern
 Built-in bytes pattern registers
 Built-in 8x8 mask registers
 Rectangle Clipping
 Transparent BitBlt with source and destination keys
 Source data in command queue Bitblt
5.19.2 Supported VGA graphics modes:
The Volari Z11M provides a 24-bit true color Digital-Analog-Converter (DAC). The maximum
frequency of the RGB is 230 MHz. The maximum resolution the DAC supports is
1600x1200@60Hz video mode (16-bit high color) or 1280x1024@85Hz video mode (true
color 32-bit).All Standard VGA modes are supported. The color palette, with 256 24-bit
entries, converts a color code that specifies the color of a pixel into three 8-bit values, one each
for red, green and blue. The 24-bit true color DAC is designed for direct color graphics mode.
It converts each digital color value to three analog voltages for red, green, and blue.
