Embedded software design for MPSoC needs parallel programming. Popular programming languages such as C and C++ are not adequate for initial specification since they are designed for sequential execution. Therefore models of computations that express concurrency naturally are preferred for initial specification, among which dataflow model has been widely used to specify signal processing applications. While software generation from SDF specification has been researched extensively, data- parallelism has not been properly considered in the previous work. This paper presents data-parallel code generation technique from SDF graphs. We use OpenMP directives to specify data-parallelism and resort OpenMP compiler to obtain the final target code. Preliminary experimentation with real-life examples shows the viability of the proposed technique.
