Abstract

Synchronous programming models capture concurrency in computation quite naturally, especially in its dataflow multi-clock (polychronous) flavor. With the rising importance of multi-core processors in safety-critical embedded systems or cyber-physical systems (CPS), there is a growing need for model-driven generation of multi-threaded code for multi-core systems. This paper proposes a build method of timepredictable system on multi-core, based on synchronous-model development. At the modeling level, the synchronous abstraction allows deterministic time semantics. Thus synchronous programming is a good choice for time-predictable system design. At the compiler level, the verified compiler from the synchronous language SIGNAL to our intermediate representation (S-CGA, a variant of guarded actions) and to multi-threaded code, preserves the time predictability. At the platform level, we propose a time-predictable multi-core architecture model in AADL (Architecture Analysis and Design Language), and then we map the multi-threaded code to this model. Therefore, our method integrates time predictability across several design layers.
