Abstract

We present a layered end-to-end approach for the design and implementation of embedded software on a distributed platform. The approach comprises a high-level modeling and simulation layer (Simulink), a middle-level programming and validation layer (SCADE/Lustre) and a low-level execution layer (TTA). We provide algorithms and tools to pass from one layer to the next. First, a translator from Simulink to Lustre. Second, a set of real-time and code-distribution extensions to Lustre. Third, implementation techniques for decomposing a Lustre program into tasks and messages, scheduling the tasks and messages on the processors and the bus, distributing the Lustre code on the execution platform, and generating the necessary "glue" code.
