Graphics Controller - Kontron CP6500-V User Manual

Functional Description
2.2.12

Graphics Controller

The 815-B0 includes an integrated graphics accelerator delivering high performance 3D, 2D
video capabilities. The internal graphics controller provides interfaces to a standard
progressive scan monitor. This interface is only active when running in internal graphics mode.
Integrated 2D/3D Graphics:
• 3D hyperpipelined architecture
• Full 2D hardware acceleration
• Intel 815-B0 D.V.M. Technology graphics core
• Integrated 230 MHz DAC
• Resolution up to 1600 x 1200 @ 75 Hz with 8 bits
• Integrated H/W Motion Compensation engines for software MPEG2 decode
2.2.12.1 Video Memory Usage
The 815-B0 chipset supports the new Dynamic Video Memory Technology (D.V.M.T.). This new
technology ensures the most efficient use of all available memory for maximum 3D graphics
performance. D.V.M.T. dynamically responds to application requirements allocating display
and texturing memory resources as required.
The operating system requires a minimum of 1 MB and a maximum of 6 MB of system memory
to support legacy VGA. System properties will display up to 6MB less than physical system
memory available to the operating system.
The graphics driver for the Intel 815-B0 configuration will request up to 6 MB of memory from
the OS. By reallocating memory to the system, memory is freed up for other applications when
not needed by the graphics subsystem. Thus, efficient memory usage is ensured for optimal
graphics and system memory performance.
