  2. 36. Low-power embedded Internet system design

    Author : Linus Svensson; Luleå tekniska universitet; []
    Keywords : ;

    Abstract : Small mobile wireless sensors are used in many different areas, and they are expected to become even more common in the future as the miniaturisation of electronics continues. The current trend of connecting sensors into networks, or wireless sensor networks, is expected to continue and it has the potential to revolutionise our capability to monitor the physical world.

  4. 37. Infinite Structures in Timed Systems

    Author : Pavel Krcal; Wang Yi; Joel Ouaknine; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical computer science; Teoretisk datalogi; Datalogi; Computing Science;

    Abstract : Real time systems distinguish themselves by explicitly stating timing constraints in the system specification. This requires specific methods and tools in system design to ensure such constraints. We focus on one of the methods applied in the validation phase, namely formal verification. READ MORE

  5. 38. Scheduling techniques to improve the worst-case execution time of real-time parallel applications on heterogeneous platforms

    Author : Petros Voudouris; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel applications; global; work-conserving; federated; heterogeneous multiprocessors; response time; Hard real-time systems; unrelated model; DAG; makespan;

    Abstract : The key to providing high performance and energy-efficient execution for hard real-time applications is the time predictable and efficient usage of heterogeneous multiprocessors. However, schedulability analysis of parallel applications executed on unrelated heterogeneous multiprocessors is challenging and has not been investigated adequately by earlier works. READ MORE

  6. 39. Hierarchical scheduling for predictable execution of real-time software components and legacy systems

    Author : Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Moris Behnam; Giuseppe Lipari; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; component integration and reuse; hierarchical scheduling; multicore; Computer Science; datavetenskap;

    Abstract : This dissertation presents techniques to achieve predictable execution of coarse-grained software components and for preservation of temporal properties of components during their integration and reuse.The dissertation presents a novel concept runnable virtual node (RVN) which interaction with the environment is bounded both by a functional and a temporal interface, and the validity of its internal temporal behaviour is preserved when integrated with other components or when reused in a new environment.

  7. 40. Resource Sharing in Real-Time Systems on Multiprocessors

    Author : Farhang Nemati; Thomas Nolte; James H Anderson; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Science; datavetenskap;

    Abstract : In recent years multiprocessor architectures have become mainstream, and multi-core processors are found in products ranging from small portable cell phones to large computer servers. In parallel, research on real-time systems has mainly focused on traditional single-core processors. READ MORE
