NEC VT 300i Personal Computer User Manual


 
4-16 System Board
The following graphics boards are available from NEC CSD:
ATI Minden (Rage IIC) 4-MB AGP board
This board contains 4 MB of SDRAM.
ATI XPERT98 (RagePRO) 4-MB AGP board with 4-MB upgrade
This board contains 8 MB of SDRAM.
Diamond Viper V550 TnT 16 MB AGP graphics board
This board contains 16 MB of video memory.
To view photorealistic images, enhance presentation graphics, and view
TV-quality MPEG video, connect a standard VGA-compatible monitor to the
AGP board external VGA monitor connector.
Accelerated Graphics Port
The system board contains a 132-pin accelerated graphics port (AGP) slot on the
system board that supports graphics-intensive, 3D applications. The AGP
operates independently of the PCI bus and supports 133-MHz data transfer rates,
allowing 500 MB of data to be transmitted per second.
The AGP is Plug and Play compatible and supports the ATI Minden AGP, ATI
XPERT AGP, and Diamond Viper graphics boards available from NEC CSD.
With the graphics board installed in the AGP slot, attach the display monitor to
the board’s VGA-compatible connector on the rear panel.
Graphics Controller
The graphics controller is specifically designed for graphics-intensive
operations, including 3D and 2D effects, texture mapping, text and color pixel
amplification, and video acceleration. The controller minimizes bus traffic by
off-loading the tasks normally performed by the processor, providing 64-bit,
high resolution performance for demanding True Color displays and other
sophisticated graphics functions.
Motion Video Controller
The motion video controller integrates a Windows graphical user interface
(GUI) engine and motion video playback hardware.
Support includes:
MPEG-1 or MPEG-2
Video for Windows
Active Movie (Windows 95 only).
MPEG is a compression/decompression standard developed by a professional
video group called the Motion Picture Experts Group. MPEG produces full-
screen, 30-frames-per-second (fps), broadcast-quality digital video.
