MPEG is a compression/decompression standard developed by the Motion Picture Experts
Group. MPEG produces full-screen 30 fps, broadcast-quality digital video. The video
controller architecture maximizes the motion video performance and removes bandwidth
bottlenecks to display multimedia data at its full speed.
Graphics Accelerator
The graphics accelerator is specifically designed for graphics-intensive operations, text and
color pixel amplification, and scrolling. The graphics accelerator provides 64-bit, ultra-high
performance for demanding True Color, High Color, and pseudocolor GUI and CAD
applications.
The accelerator minimizes bus traffic by off-loading the tasks normally performed by the
processor. The dedicated bit-block transfers (BitBLT) engine maximizes performance by
speeding the movement of large blocks of image data in video memory.
Video Memory
The system comes with 1 MB of on-board video DRAM, upgradeable to 2 MB. The
standard 1 MB DRAM consists of two 512 KB by 16 DRAM devices soldered to the
system board. The optional 1 MB of DRAM consists of two 512 KB by 16 modules that
install in two sockets on the system board.
With the standard 1 MB of video DRAM, the video hardware supports the following
resolutions, colors, and refresh rates:
T
1280 by 1024 pixels, 16 colors, 60 Hz
T
1024 by 768 pixels, 16/256 colors, 60 Hz, 70 Hz, 75 Hz, and 85 Hz
T
800 by 600 pixels, 16/256/64K colors, 56 Hz, 60 Hz, 72 Hz, 75 Hz, and 85 Hz
T
640 by 480 pixels, 16/256/64K/16 million colors, 60 Hz, 72 Hz, 75 Hz and 85 Hz
With 2 MB of video DRAM, the system supports the following additional resolutions,
colors, and refresh rates:
T
1280 by 1024 pixels, 256 colors, 60 Hz and 75 Hz
T
1024 by 768 pixels, 64K/16 million colors, 60 Hz, 70 Hz, 75 Hz and 85 Hz
T
800 by 600 pixels, 16 million colors, 56 Hz, 60 Hz, 72 Hz, 75 Hz, and 85 Hz
T
640 by 480 pixels, 16 million colors, 60 Hz, 72 Hz, 75 Hz, and 85 Hz.
