4. 2. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

   Author : Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Computer Science with specialization in Real Time Systems; Datavetenskap med inriktning mot realtidssystem;

   Abstract : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. READ MORE

5. 3. On robust and optimal control : with real time aspects

   Author : Torbjörn Norlander; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

   Abstract : This thesis deals with several issues in realistic design of control systems, both from a practical and a theoretical point of view. This is done in three papers which are preceded by an introduction and a short discussion on future research on time-varying delays. The first paper discusses the importance of reliable sensors in control systems. READ MORE

6. 4. Automatic memory management for flexible real-time systems

   Author : Sven Robertz; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; feedback scheduling; embedded systems; real-time; memory management; garbage collection; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll;

   Abstract : In a flexible real-time system, the constraints in available CPU time and memory lead to resource management problems, which must be handled carefully in order to maximize quality of service while avoiding overload. Managing CPU time -- scheduling -- is well studied and dynamic scheduling is widely accepted in the real-time industry. READ MORE

7. 5. Energy-Centric Scheduling for Real-Time Systems

   Author : Flavius Gruian; Institutionen för datavetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; numerisk analys; Datalogi; Computer science; numerical analysis; System-Level Synthesis; Variable Speed Processors; Dynamic Voltage Scaling; Real-Time Scheduling; Energy Efficient Systems; control; systems; system; kontroll;

   Abstract : Energy consumption is today an important design issue for all kinds of digital systems, and essential for the battery operated ones. An important fraction of this energy is dissipated on the processors running the application software. To reduce this energy consumption, one may, for instance, lower the processor clock frequency and supply voltage. READ MORE
