1. 6. Parametric WCET Analysis

   Författare :Stefan Bygde; Björn Lisper; Raimund Kirner; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WCET Analysis; parametric WCET Analysis; WCET; Timing; Computer Science; datavetenskap;

   Sammanfattning : In a real-time system, it is crucial to ensure that all tasks of the system hold their deadlines. A missed deadline in a real-time system means that the system has not been able to function correctly. If the system is safety critical, this could potentially lead to disaster. LÄS MER

3. 7. Towards Aspectual Component-Based Real-Time System Development

   Författare :Aleksandra Tešanović; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aspect-oriented software development; component-based software development; real-time systems; embedded systems; database systems; aspects; components; worst-case execution time; Computer science; Datavetenskap;

   Sammanfattning : Increasing complexity of real-time systems and demands for enabling their configurability and tailorability are strong motivations for applying new software engineering principles such as aspect-oriented and component-based software development. The integration of these two techniques into real-time systems development would enable: (i) efficient system configuration from the components in the component library based on the system requirements, (ii) easy tailoring of components and/or a system for a specific application by changing the behavior (code) of the component by aspect weaving, and (iii) enhanced flexibility of the real-time and embedded software through the notion of system configurability and component tailorability.

4. 8. Developing Reusable and Reconfigurable Real-Time Software using Aspects and Components

   Författare :Aleksandra Tešanović; Jörgen Hansson; Heinz W. Schmidt; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; embedded systems; software components; aspect-oriented software; quality of service; worst-case execution time; database systems; Software engineering; Programvaruteknik;

   Sammanfattning : Our main focus in this thesis is on providing guidelines, methods, and tools for design, configuration, and analysis of configurable and reusable real-time software, developed using a combination of aspect-oriented and component-based software development. Specifically, we define a reconfigurable real-time component model (RTCOM) that describes how a real-time component, supporting aspects and enforcing information hiding, could efficiently be designed and implemented.

5. 9. Analysis and Optimisation of Real-Time Systems with Stochastic Behaviour

   Författare :Sorin Manolache; Petru Eles; Zebo Peng; Xiaobo Hu; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded systems; Real-time systems; System level design and optimisation; Stochastic execution times; Performance analysis; Networks-on-chip; Computer science; Datavetenskap;

   Sammanfattning : Embedded systems have become indispensable in our life: household appliances, cars, airplanes, power plant control systems, medical equipment, telecommunication systems, space technology, they all contain digital computing systems with dedicated functionality. Most of them, if not all, are real-time systems, i.e. LÄS MER

7. 10. Scheduling Garbage Collection in Embedded Systems

   Författare :Roger Henriksson; Institutionen för datavetenskap; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; memory management; garbage collection; real-time; embedded systems; hard deadlines; run-time systems; Systems engineering; scheduling analysis; Data- och systemvetenskap; computer technology;

   Sammanfattning : The complexity of systems for automatic control and other safety-critical applications grows rapidly. Computer software represents an increasing part of the complexity. As larger systems are developed, we need to find scalable techniques to manage the complexity in order to guarantee high product quality. LÄS MER
