Development of a Streaming Application Benchmark Set

Future requirements of embedded systems can only be fulfilled using multiprocessor systems. One challenge of these systems is to efficiently program applications. The DOL framework addresses this problem by allowing the specification of applications as Kahn process networks and by mapping these applications to multiprocessor architectures. This semester thesis proposes a set of benchmark applications which can be used to evaluate the peak computational performance and peak communication bandwidth of applications executing on several heterogeneous multiprocessor systems in which inter-processor communication is achieved via message passing. These applications have been designed as synchronous data flows and have been developed within the DOL framework. In a second step, several alternative configurations of them have been used to evaluate the performance of the Sony/Toshiba/IBM Cell Broadband Engine. To this end, the existing DOL code generation back-end for the CBE has been revisited and improved so that the corresponding run-time environment can be used as a reliable platform for experiments.
