Abstract:
Many systems consist of a signal processing and a control dominated part. The interaction of the data processing functions and a large variety of system-level control functions are often complex and with far reaching consequences. Thus, an early analysis and assessment of this interaction in a system level model is desirable. We propose a heterogeneous cosimulation environment with Matlab for the signal processing parts and SDL for the control-dominated parts. We describe a communication and synchronisation technique that allows the natural usage of Matlab vectors, which often represent data samples over time periods, rather than single events at time instances. This makes the technique both natural to use and efficient in the simulation. We describe two modes of synchronisation, head synchronisation and tail synchronisation, and the conditions under which they can be used together. 1.
