Efficient Implementation of Heterogeneous Dataflow Models using Synchronous IO Patterns

The synthesis of distributed embedded systems based on desynchronization is attractive since it preserves the functional behavior of the synchronous model while avoiding the verification of the absence of problems like deadlocks and buffer overflows. In this paper, we improve the desynchronization process by introducing synchronous components with various input/output (IO) patterns which can then be desynchronized to a heterogeneous dataflow process network (DPN) where each node can be scheduled and executed accordingly. We further designed a synthesis tool chain that automatically synthesizes the heterogeneous DPN to the open computing language (OpenCL) based implementation which is platform-independent and can be deployed on various commercial off-the-shelf (COTS) target platforms.
