The O 2
Workstation: Combining Workstation
Performance with the Power of the Web
Silicon Graphics introduces O2
, the innovative desktop system that combines
Silicon Graphics performance with the power of a Web-integrated
user environment. O2 maximizes
the productivity and innovation of creative and engineering teams
with a new Web-integrated user interface combined with exceptional
compute, graphics, imaging, I/O, and video compression capabilities.
New Thinking Demands a New Architecture
The O2 workstation
is based on an innovative Unified Memory Architecture (UMA). Each
system resource (CPU, graphics, video, imaging, compression,
I/O) has equal access to the 2.1GB/second unified main memory
subsystem. The compute power of O2 is
based on the MIPS ® R5000 ™ and R10000 ™
processors, providing outstanding application
performance.
Interactive Graphics and Imaging
Performance
The O2 workstationís
standard 32-bit double buffered graphics, native OpenGL ®
graphics sub-system, and hardware support
for texture mapping and z-buffering gives users industry-leading
3D performance and quality. O2 has
a dedicated image processing
engine that accelerates operations such as convolutions. The texture
mapping hardware also allows real-time pan, zoom, and rotate of
large, high-resolution images.
Unmatched Video Processing
Standard video compression hardware
in O 2 enables every engineer
to be a video editor while providing the features and quality
that video professionals demand. In real time, O 2
encodes and decodes NTSC or PAL resolution
motion-JPEG video and decodes MPEG 1 video. Users can also record
video from the screen and save it in real time as a JPEG compressed
video file. Independent audio can be synchronized to video data.
O 2 supports two video
channels in and one video channel out.
Web-Integrated Desktop Environment
The O 2 workstation
is built network-ready, with Web browsing and TCP/IP network protocols
com-pletely integrated into the desktop user interface and operating
system. The file management system allows for the viewing of files,
folders, or the hier-archy of a Web site while browsing it. The
Silicon Graphics personal Web publisher is a standard feature,
allowing users to share information over company intranets with
an easy-to-use drag-and-drop interface. Each machine has simple
but powerful personal system administration and disk manage-ment
tools that leverage the Webís look-and-feel to help users
intuitively visualize and complete tasks such as printer installation.
NFS ™ 3.0, available
as an option, provides the highest throughput NFS file serving
in the industry.
High-Bandwidth I/O
The O 2 I/O
engine maximizes performance by removing bandwidth bottlenecks,
which can starve even the fastest system components. O 2
delivers peak performance on 10BaseT/100BaseTX
Ethernet ™ networks,
a dual Ultra Fast/Wide SCSI implementation, 64-bit PCI expansion
bus, and other I/O options.
