  abstract= "Inter-processor communications play a vital role in the
     performance of distributed parallel networks. This document
     analyses various protocol options for high speed, serial,
     inter-processor communications for use in embedded
     multiprocessor systems. The protocol is used to pass
     information in a fault tolerant routing network. The work
     has resulted in a custom processor interface, which forms
     the gateway between the processing node and the distributed
     communications network, building on previous work. The role
     of the interface is to provide maximum hardware support for
     communications between the network and the processor. This
     alleviates the processor from having to oversee
     communications transactions and allows it to concentrate on
     program execution. The research focuses on protocol
     alterations aimed at improving the fault tolerant aspects of
     the design when dealing with various forms of network
     failure. By improving the fault tolerance of the network,
     communications bottlenecks can be avoided and data
     throughput can be maximised. Previously, communications
     across the network had used the OS Links protocol and,
     experimentally, DS Links. These were analysed and adapted to
     provide the current communications protocol, which is
     compared with these protocols. This protocol is more
     efficient, and helps to provide many features to ensure data
