Code Generation for PTIDES Models

PTIDES is a programming model for distributed real-time embedded systems. PTIDES builds on Discrete-Event (DE) semantics and leverages a global notion of time throughout distributed platforms. Applications expressed in PTIDES models can be designed without any knowledge about the hardware platform upon which it is implemented, thus completely decoupling the design from the implementation. To bridge this gap, a code generator is implemented to automatically generate platformspecific C code from PTIDES models designed in Ptolemy II [1] to a particular hardware platform. This paper present our approach in generating C code from PTIDES models, and statically link them against the PtidyOS scheduling libraries to produce a realtime executable we call PtidyOS.
