Abstract:Modern streaming applications are becoming increasingly demanding, requiring higher throughput, smaller buffer sizes and execute on less resources. Synchronous dataflow (SDF) graphs are a widely used formalism for the analysis of data flow in streaming applications, for both single processor and multiprocessor applications Despite state of the art scheduling methods for SDF graphs very little visualisations options are available for people who work with SDF graphs. Interviews have shown that these tools are self made and not very matured, even though they desire to have such tools. Therefore this project has developed a visualisation tool for SDF schedules called SDF Fish. The tool can load in data files of schedules and visualise these. The visualisations exist out of a Gantt-like chart and a snapshot visualisation of the resources. Users can navigate through the schedules by time controls. Furthermore, an automatic play function is featured. In order to provide overview for bigger schedules the tool offers zoom scale and filter capabilities.
