Cyber-Physical Systems (CPS) are tightly coupled with the environment, and therefore it is important that interactions with the surroundings like Human-Computer-Interactions are performed very responsive. Since CPS are often embedded without traditional input devices, like in medical or automotive contexts, gesture recognition approaches are emerging. As those algorithms are computationally complex...
The timed dataflow model of computation is a useful performance analysis tool for Electronic System Level Design automation and embedded software synthesis. Its determinism gives it strong analysability properties. It is expressive enough to cover a large class of applications and platforms. The trend however, in both embedded applications and their platforms is to become more dynamic, reaching the...
Latest trends in embedded platform architectures show a steady shift from high frequency single core platforms to lower-frequency but highly-parallel execution platforms. Scheduling applications with stringent latency requirements on such multiprocessor platforms is challenging. Our work is motivated by the scheduling challenges faced by ASML, the world's leading provider of wafer scanners. A wafer...
Various dataflow formalisms have been used for capturing the potential parallelism in streaming applications to realise distributed (multi-core) implementations as well as for analysing key properties like absence of deadlock, throughput and buffer occupancies. The recently introduced formalism of Scenario-Aware Dataflow (SADF) advances these abilities by appropriately capturing the dynamism in modern...
Embedded multimedia and wireless applications require a model-based design approach in order to satisfy stringent quality and cost constraints. The Model-of-Computation (MoC) should appropriately capture system dynamics, support analysis and synthesis, and allow low-overhead model-driven implementations. This combination poses a significant challenge. The Scenario-Aware DataFlow (SADF) MoC has been...
Increasingly more MPSoC platforms are being developed to meet the rising demands from concurrently executing applications. These systems are often heterogeneous with the use of dedicated IP blocks and application domain specific processors. While there is a host of research done to provide good performance guarantees and to analyze applications for preemptive uniprocessor systems, the field of heterogeneous,...
