An automated control code generation approach for the SegBus platform

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.
