A Predictable Multiprocessor Design Flow for Streaming Applications with Dynamic Behaviour

—The design of new embedded systems is getting more and more complex as more functionality is integrated into these systems. To deal with the design complexity, a predictable design flow is needed. The result should be a system that guarantees that an application can perform its own tasks within strict timing deadlines, independent of other applications running on the system. Synchronous Dataflow Graphs (SDFGs) provide predictability and are often used to model time-constrained streaming applications that are mapped onto a multiprocessor platform. However, the model s from the dynamic application behaviour which may lead to a large overestimation of its resource requirements. We present a design flow that takes the dynamic behaviour of applications into account when mapping them onto a multiprocessor platform. The design flow provides throughput guarantees for each application independent of the other applications while taking into account the available processing capacity, memor...
