  1. 1. Synthesis of Safety-Critical Real-Time Systems

    Författare :Yuanbin Zhou; Zebo Peng; Petru Ion Eles; Soheil Samii; Luis Almeida; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Safety-Critical Systems; Real-Time Systems; Time-Sensitive Networking; Mixed-Criticality Systems;

    Sammanfattning : Modern safety-critical real-time systems are becoming more and more complex, due to sophisticated applications such as advanced driving assistance, automated driving, advanced infotainment, and applications involving machine learning and deep learning. This has led to increased requirements for the communication infrastructures. LÄS MER

  3. 2. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

    Författare :Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-time systems; Scheduling; Schedulability analysis; Preemptions; Preemption delays; Embedded Systems; Preemptive scheduling; Response-time analysis; Cache-related preemption delay; Timing analysis; Worst-case execution time analysis; Limited-preemptive scheduling; Fixed preemption points; Computer Science; datavetenskap;

    Sammanfattning : Schedulability analysis of real-time systems under preemptive scheduling may often lead to false-negative results, deeming a schedulable taskset being unschedulable. This is the case due to the inherent over-approximation of many time-related parameters such as task execution time, system delays, etc. LÄS MER

    Sammanfattning : Ubiquitous deployment of embedded systems is having a substantial impact on our society, since they interact with our lives in many critical real-time applications. Typically, embedded systems used in safety or mission critical applications (e.g. LÄS MER

  5. 4. Real-Time Services in Packet-Switched Networks for Embedded Applications

    Författare :Xing Fan; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded systems; real-time communication; packet-switching; swithed Ethernet; FCFS and EDF scheduling; schedulability analysis; active networking; protocol overhead; Computer science; Datalogi; Computer science; Datavetenskap;

    Sammanfattning : Embedded applications have become more and more complex, increasing the demands on the communication network. For reasons such as safety and usability, there are real-time constraints that must be met. Also, to offer high performance, network protocols should offer efficient user services aimed at specific types of communication. LÄS MER

  7. 5. Hierarchical scheduling for predictable execution of real-time software components and legacy systems

    Författare :Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Moris Behnam; Giuseppe Lipari; Mälardalens högskola; []
    Nyckelord :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;

    Sammanfattning : 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.
