Technical Information 1-17MPEG is a compression/decompression standard developed by the Motion Picture ExpertsGroup. MPEG produces full-screen 30-fps, broadcast-quality digital video. The videocontroller architecture maximizes the motion video performance and removes bandwidthbottlenecks to display multimedia data at its full speed.Graphics AcceleratorThe graphics accelerator is specifically designed for graphics-intensive operations, text andcolor pixel amplification, and scrolling. The graphics accelerator provides 64-bit, ultra-highperformance for demanding True Color, High Color, and pseudocolor GUI and CADapplications.The accelerator minimizes bus traffic by off-loading the tasks normally performed by theprocessor. The dedicated bit-block transfers (BitBLT) engine maximizes performance byspeeding the movement of large blocks of image data in video memory.Video MemoryThe PowerMate Office 2513/2516 Series systems come standard with 1 MB of on-boardvideo EDO DRAM. The standard 1 MB EDO DRAM consists of two 256 KB by 16 EDODRAM devices soldered to the system board.The system is upgradeable to 2 MB with the addition of 1 MB of EDO DRAM. Theupgrade consists of two 256 KB by 16 modules that install in two sockets on the systemboard.The system is further upgradeable to 4 MB with the addition of 2 MB of video memory ona 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.
