1. 1. Methods for Efficient and Adaptive Scheduling of Next-Generation Time-Triggered Networks

   Författare :Francisco Manuel Pozo Pérez; Guillermo Rodriguez-Navas; Hans Hansson; Petru Eles; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

   Sammanfattning : Real-time networks play a fundamental role in embedded systems. To meet timing requirements, provide low jitter and bounded latency in such networks the time-triggered communication paradigm is frequently applied in such networks. In this paradigm, a schedule specifying the transmission times of all the traffic is synthesized a priori. LÄS MER

3. 2. Scheduling and Communication Synthesis for Distributed Real-Time Systems

   Författare :Paul Pop; Petru Eles; Zebo Peng; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed embedded systems; hard real-time systems; time-triggered protocol; scheduling; schedulability analysis; communication synthesis; control dependencies; Computer science; Datavetenskap;

   Sammanfattning : Embedded systems are now omnipresent: from cellular phones to pagers, from microwave ovens to PDAs, almost all the devices we use are controlled by embedded systems. Many embedded systems have to fulfill strict requirements in terms of performance and cost efficiency. LÄS MER

4. 3. On the Design and Validation of Fault Containment Regions in Distributed Communication Systems

   Författare :Håkan Sivencrona; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault handling and membership agreement; Byzantine faults; asymmetric faults; fault injection; time-triggered protocol; fault containment regions; slightly-out-of-specification faults; validation;

   Sammanfattning : This thesis has a two fold focus where the first is an evaluation of a time-triggered communication protocol implementation, TTP-C1, which was stressed by use of heavy-ion fault injection. The gathered result showed a novel type of failures, earlier known only from theory, so-called slightly-out-of-specification faults, that manifested as Byzantine failures with resulting system inconsistence.

5. 4. Scheduling and Optimisation of Heterogeneous Time/Event-Triggered Distributed Embedded Systems

   Författare :Traian Pop; Petru Eles; Zebo Peng; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; embedded computer systems; safety-critical applications; real-time behavior; time-triggered TT ; event-triggered ET ; Computer science; Datavetenskap;

   Sammanfattning : Day by day, we are witnessing a considerable increase in number and range of applications which entail the use of embedded computer systems. This increase is closely followed by the growth in complexity of applications controlled by embedded systems, often involving strict timing requirements, like in the case of safety-critical applications.

7. 5. Analysis and Optimisation of Distributed Embedded Systems with Heterogeneous Scheduling Policies

   Författare :Traian Pop; Petru Ion Eles; Zebo Peng; Luis Almeida; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed embedded systems; Real-time analysis; Scheduling; Design optimisation; FlexRay; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : The growing amount and diversity of functions to be implemented by the current and future embedded applications (like, for example, in automotive electronics) have shown that, in many cases, time-triggered and event-triggered functions have to coexist on the computing nodes and to interact over the communication infrastructure. When time-triggered and event-triggered activities have to share the same processing node, a natural way for the execution support can be provided through a hierarchical scheduler. LÄS MER
