136 RS/6000 43P 7043 Models 150 and 260 Handbook
The GXT120P is also ideal for process control, where, in selected
configurations, up to four monitors can be operated concurrently from the
same RS/6000 system for displaying graphics and text for dozens of process
points. For decision support systems, the GXT120P provides opportunities
for rapid, simultaneous display of large amounts of critical information at high
resolution on up to four screens.
The GXT120P accelerates UMS/6000 video playback on RS/6000 systems
with up to 640 Mbps memory bandwidth. UMS/6000 is an IBM Licensed
Program Product that includes video capture, multiple window playbacks and
video scaling. Both X and Y interpolative scaling are implemented by the
accelerator for zooming and mapping to windows. It can support up to three
video streams concurrently. The video scaling feature can be used for
collaborative computing and playback of live and stored video.
The GXT120P supports screen resolutions of 640x480, 800x600, 1024x768,
and 1280x1024 all at 8-bits per pixels. It satisfies the ISO 9241 standard of
visual quality at all these resolutions, refreshing the screen at up to 85 Hz for
all resolutions, including the 1280x1024 8-bit resolution.
The GXT120P graphics accelerator is a half-length PCI card with a standard
15-pin DIN output connector.
5.2.2 POWER GXT250P (# 2851) and POWER GXT255P (# 2852)The POWER GXT250P and GXT255P graphics accelerators provide solid
graphics performance at an attractive price. These accelerators supply
excellent 2D 8-bit, 16-bit, or 24-bit graphics performance for the RS/6000 43P
Series systems. The POWER GXT250P provides a high level of 8-bit 2D
graphics performance, while the GXT255P provides 3D graphics
performance at entry 2D graphics prices. When coupled with IBM’s
Softgraphics implementation of the OpenGL, graPHIGS, and PEX 3D APIs,
these accelerators offer an exciting level of 3D performance. With
high-quality 8-bit double buffer or 24-bit single buffer performance, these
graphics accelerators help provide sharper graphical imagery on your screen.
The POWER GXT250P supports 8-bit color depth that allows simultaneous
display of up to 256 colors from a palette of approximately 16.7 million colors.
With its 3 MB of VRAM (2 MB frame buffer plus 1 MB auxiliary buffer), the
POWER GXT250P can meet the demanding needs of most popular graphics
applications.
The POWER GXT255P graphics accelerator extends the graphics capability
to 24-bit true color required in many high-tech design applications such as
