Integrated Graphics
The system has an SiS 6205 PCI local bus motion video playback controller and graphics
accelerator integrated on the system board. State of the art techniques are used for
optimizing performance in computer graphic intensive applications and graphical user
interfaces (GUI).
The integrated graphics controller integrates a motion video controller, a high-performance
GUI accelerator, 24-bit high frequency DAC and clock generator, VESA
®
-compliant
feature connector, and 1 MB of fast 64-bit DRAM (upgradeable to 2 MB).
Motion Video Controller
The motion video controller integrates a powerful Windows
®
GUI engine and unique
motion video playback hardware for superior performance. The graphics engine includes an
on-chip color space converter to accelerate decompression and a hardware scaler to scale
continuously from native size up to full screen at full speed. The graphics engine delivers a
full screen, smooth display of motion video data up to 30 frames per second (fps). Support
includes MPEG-1 (multimedia systems only) and Video for Windows.
