2. 1. !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

4. 2. Configurable Hardware Support for Single Processor Real-Time Systems

   Author : Susanna Nordström; Lars Asplund; Kristina Lundqvist; Krzysztof Kuchcinski; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; FPGA; real-time system; real-time kernel; RTOS; real-time operating system; vhdl; embedded system; Computer engineering; Datorteknik; Datavetenskap;

   Abstract : This thesis describes a further development of a building block for programmable devices in embedded systems handling real-time functionality.Embedded systems are included in a variety of products within different technical areas such as industrial automation, consumer electronics, automotive industry, and communication-, and multimedia systems.

5. 3. 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

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. Security-Driven Design of Real-Time Embedded Systems

   Author : Ke Jiang; Zebo Peng; Petru Eles; Axel Jantsch; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Security; Embedded System; Real-Time System; Design; Optimization;

   Abstract : Real-time embedded systems (RTESs) have been widely used in modern society. And it is also very common to find them in safety and security critical applications, such as transportation and medical equipment. READ MORE
