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. !secure(system) <=?=> !safe(system) : On Security and Safety of Industrial Software Systems

   Author : Marcus Lindner; Per Lindgren; Valeriy Vyatkin; Knut Åkesson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; hard real-time; concurrency; model of computation; safety-critical; safety; security; industrial automation; RTFM; real-time for the masses; Embedded Systems; Inbyggda system;

   Abstract : The focus of our research work is on readily accessible, embedded, real-time development with concurrency support. To this end, we develop the Real-Time For the Masses (RTFM) programming framework with a model of computation based on tasks and resources and that stipulates a timing semantics. 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. 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

7. 5. Scheduling and Communication Synthesis for Distributed Real-Time Systems

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

   Abstract : 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. READ MORE
