%X 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
integrity.
