Combining multiple models of computation for scheduling and allocation

Many applications include a variety of functions from different domains. Therefore, they are best modeled with a combination of different modeling languages. For a sound design process and improved design space utilization, these different input models should be mapped to a common representation. In this paper, we present a common internal representation that integrates the aspects of several models of computation and is targeted to scheduling and allocation. The representation is explained using an example combining a classical process model as used in real-time operating systems (RTOS) with the synchronous data flow model (SDF).
