We present here a model-driven approach for the generation of low-level control code for the arbiters, to support application implementation and scheduled execution on a multi-core segmented bus platform, SegBus. The approach considers Model-Driven Architecture as a key to model the application at two different abstraction levels, namely as Packet-Synchronous Dataflow and Platform Specific Model, using the SegBus platform's Domain Specific Language. Both models are transformed into Extensible Markup Language schemes, and then utilized by an emulator program to generate the “application-dependent” VHDL code, the so-called “snippets”. The obtained code is inserted in a specific section of the platform arbiters. We present an example of a simplified stereo MP3 decoder where the methodology is employed to generate the control code of arbiters.
