Technical Information 1-17
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 PowerMate Office 2513/2516 Series systems come standard with 1 MB of on-board
video EDO DRAM. The standard 1 MB EDO DRAM consists of two 256 KB by 16 EDO
DRAM devices soldered to the system board.
The system is upgradeable to 2 MB with the addition of 1 MB of EDO DRAM. The
upgrade consists of two 256 KB by 16 modules that install in two sockets on the system
board.
The system is further upgradeable to 4 MB with the addition of 2 MB of video memory on
a video memory card.
With 1 MB of video EDO DRAM, the video hardware supports the following resolutions,
colors, and refresh rates:
1024 by 768 pixels, 16/256 colors, 60 Hz, 66 Hz, 70 Hz, 72 Hz, and 75 Hz
800 by 600 pixels, 16/256/64K colors, 56 Hz, 60 Hz, 72 Hz, and 75 Hz
640 by 480 pixels, 16/256/64K/16.8 colors, 60 Hz, 72 Hz, and 75 Hz.
With 2 MB of video EDO DRAM, the system supports the following resolutions, colors,
and refresh rates:
1024 by 768 pixels, 256/64K colors, 60 Hz, 66 Hz, 70 Hz, 72 Hz, and 75 Hz
800 by 600 pixels, 256/64K/16.8 million colors, 56 Hz, 60 Hz, 72 Hz, and 75 Hz
640 by 480 pixels, 16/256/64K/16.8/32 bit million colors, 56 Hz, 60 Hz, 72 Hz,
and 75 Hz.
