| 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. |
