Diplomat: Mapping of Multi-kernel Applications Using a Static Dataflow Abstraction
Bruno Bodin, Luigi Nardi, Paul H. J. Kelly, Michael O’Boyle · 2016
In this paper we propose a novel approach to heterogeneous embedded systems programmability using a task-graph based framework called Diplomat. Diplomat is a task-graph framework that exploits the potential of static dataflow modeling and analysis to deliver performance estimation and CPU/GPU mapping. An application has to be specified once, and then the framework can automatically propose good mappings. We evaluate Diplomat with a computer vision application on two embedded platforms. Using the Diplomat generation we observed a 16% performance improvement on average and up to a 30% improvement over the best existing hand-coded implementation.
