1. 6. Programming Language Primitives and Tools for Integrated Real-Time Systems Development

   Författare :Saranya Natarajan; David Broman; Haibo Zeng; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Real-Time System; Programming Language; Compiler; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The correctness of real-time systems depends on both its logical and temporal correctness. Typically, real-time systems are developed in several steps. First, the application is divided into a number of recurrent tasks and implemented using a programming language. LÄS MER

3. 7. Hierarchical scheduling for predictable execution of real-time software components and legacy systems

   Författare :Rafia Inam; Mikael Sjödin; Jukka Mäki-Turja; Moris Behnam; Giuseppe Lipari; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; real-time systems; component integration and reuse; hierarchical scheduling; multicore; Computer Science; datavetenskap;

   Sammanfattning : This dissertation presents techniques to achieve predictable execution of coarse-grained software components and for preservation of temporal properties of components during their integration and reuse.The dissertation presents a novel concept runnable virtual node (RVN) which interaction with the environment is bounded both by a functional and a temporal interface, and the validity of its internal temporal behaviour is preserved when integrated with other components or when reused in a new environment.

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

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

   Sammanfattning : 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. LÄS MER

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

   Författare :Marcus Lindner; Per Lindgren; Valeriy Vyatkin; Knut Åkesson; Luleå tekniska universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

7. 10. Embedded real-time software using TinyTimber : reactive objects in C

   Författare :Johan Eriksson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inbyggda system; Embedded System;

   Sammanfattning : Embedded systems are often operating under hard real-time constraints. Such systems are naturally described as time-bound reactions to external events, a point of view made manifest in the high-level programming and systems modeling language Timber. LÄS MER
