In this Master's thesis a run-time reconfiguration mechanism for multi-DSP
systems with point-to-point communication has been developed to improve
testability and maintainability. This mechanism is an extension of the
rapid prototyping system PEPSY which allows the development of data-flow
driven real-time applications. First, existing rapid prototyping systems,
data-flow models and multi-DSP operating systems are investigated and
compared. Principles of fault tolerance, test and reconfiguration are
outlined. Second, an overview of PEPSY is given and the basic functions of
the run-time reconfiguration mechanism are discussed. Subsequently,
implementational details of the mechanism and the data transfer protocol
between the host and the multi-DSP system are shown. Finally, in an
experimental evaluation the quality and temporal behavior of the
implementation are investigated.
