Abstract
The introduction of gigabit local area networks and the resultant
proliferation of multimedia applications will require fundamental
changes in the design of computer workstations. The workstation is
implemented as a distributed application on a local area network in
order to focus on communications issues. A single processor is dedicated
to the low-level functions of acquiring image and audio streams from the
network and sending keyboard and mouse information to the network. The
display processor receives only bitmap images of data to be displayed.
Higher level functionality, like that provided by the X-window system,
is handled by other processors in the network. To demonstrate the
feasibility of this architecture, a prototype monochrome (bilevel black
and white) workstation was built that is able to simultaneously display
several windows with 30 frame/s video, each arriving from a different
processor via a local area interconnect. The feasibility of interleaving
real-time video images across multiple disks on different processors to
provide sufficient throughput for full-motion video is demonstrated. A
simple method provides video and sound which are synchronized with each
other and which flow smoothly
