A novel approach for interactive debugging of dynamic dataflow embedded applications

In this paper, we propose a new approach for source-level dataflow debuggers. Going beyond their long-established ability to support sequential programming languages, we describe the functionalities a debugger should be able to provide to debug embedded and parallel dataflow applications. Then we demonstrate our solution to this problem with a proof-of-concept debugger targeting the dataflow framework used on an industrial MPSoC platform. We also explain the development challenges we faced during the implementation of this GDB-based debugger.
