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

   Author : Filip Marković; Jan Carlson; Radu Dobrin; Björn Lisper; Enrico Bini; Mälardalens högskola; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Multi-Threaded Distributed System Simulations : Using Bi-Lateral Delay Lines

   Author : Robert Braun; Petter Krus; Asko Ellman; Linköpings universitet; []
   Keywords : ;

   Abstract : As the speed increase of single-core processors keeps declining, it is important to adapt simulation software to take advantage of multi-core technology. There is a great need for simulating large-scale systems with good performance. READ MORE

5. 3. LQG-Based Real-Time Scheduling and Control Codesign

   Author : Yang Xu; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LQG control; Real-time system; Scheduling; Time-delay system;

   Abstract : Having multiple control tasks concurrently running on a single computing platform increases the processor utilization but degrades the control performance due to delay and jitter. In scheduling and control codesign, the objective is to optimize the combined performance of all the controllers, subject to a schedulability constraint. READ MORE

6. 4. Dynamic Programming and Time-Varying Delay Systems

   Author : Bo Lincoln; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control engineering; Automatiska system; robotteknik; reglerteknik; robotics; Automation; Stability analysis; Time-varying delays; Dynamic programming; Switched linear systems;

   Abstract : This thesis is divided into two separate parts. The first part is about Dynamic Programming for non-trivial optimal control problems. The second part introduces some useful tools for analysis of stability and performance of systems with time-varying delays. READ MORE

7. 5. Improving the Schedulability of Real Time Systems under Fixed Preemption Point Scheduling

   Author : Filip Markovic; Jan Carlson; Radu Dobrin; Björn Lisper; Sebastian Altmeyer; José Javier Gutiérrez; Christian Berger; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Limited Preemptive Scheduling; Fixed Preemption Points Scheduling; Probabilistic response time analysis; Cache-Related Preemption Delay Analysis; Computer Science; datavetenskap;

   Abstract : During the past decades of research in Real-Time systems, non-preemptive scheduling and fully preemptive scheduling have been extensively investigated, as well as compared with each other. However, it has been shown that none of the two scheduling paradigms dominates over the other in terms of schedulability. READ MORE
