  abstract= "This paper describes Weave, a system which has been
     developed to support the use of a DS Link (IEEE 1355) based
     parallel computer architecture. Weave is an extension layer
     on IIPC (a simple transputer and UNIX parallel processing
     environment which provides dynamic process management,
     hardware transparency and message passing.) Although Weave
     is suitable for any T9000 Transputer network, it has been
     specifically designed to support the use of the AIVRU DS
     Link Vision Engine. A brief description is given of this
     machine, which processes live digital video using a mixture
     of hardware modules and software processes, all
     interconnected by DS Links. Weave provides the ability to
     make virtual link connections between processes on demand at
     run-time. These connections may be disconnected when no
     longer required, and hence the whole hardware architecture
     is dynamically reconfigured automatically to suit the
     requirements of the software application. A small functional
     interface provides processes with the ability to alter their
     own connectivity, and that of other processes. A temporal
     locking mechanism for each virtual link controls when it may
     be disconnected, and when pending connection requests can be
     fulfilled. This locking mechanism is driven by the action of
     communication over the virtual link. The Weave system
     supports transparently, the creation and destruction of
     connections between software processes and the image
     processing hardware modules (and between hardware modules
     directly). Also provided transparently by Weave is support
     for the use of hardware message replicator module(s) that
     multicast virtual link data to any number of DS Link
     recipients."
