Dataflow analysis techniques are key to reduce the number of design iterations
and shorten the design time of real-time embedded network based multiprocessor
systems that process data streams. With these analysis techniques the worstcase
end-to-end temporal behavior of hard real-time applications can be derived
from a dataflow model in which computation, communication and arbitration
is modeled. For soft real-time applications these static dataflow analysis techniques
are combined with simulation of the dataflow model to test statistical
assertions about their temporal behavior. The simulation results in combination
with properties of the dataflow model are used to derive the sensitivity of design
parameters and to estimate parameters like the capacity of data buffers.
