1. 1. Parametric WCET Analysis

   Författare :Stefan Bygde; Björn Lisper; Raimund Kirner; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WCET Analysis; parametric WCET Analysis; WCET; Timing; Computer Science; datavetenskap;

   Sammanfattning : In a real-time system, it is crucial to ensure that all tasks of the system hold their deadlines. A missed deadline in a real-time system means that the system has not been able to function correctly. If the system is safety critical, this could potentially lead to disaster. LÄS MER

3. 2. Timing parenthood : Independence, family and ideals of life

   Författare :Disa Bergnéhr; Gunilla Halldén; Ann Phoenix; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; fertility; postponed parenthood; timing parenthood; family formation; ideals of life; independence; belonging; risk; discourse analysis; focus group method.; fertilitet; uppskjutet barnafödande; tid för föräldraskap; familjebildning; livsideal; oberoende; tillhörighet; risk; diskursanalys; fokusgruppsmetod.; Children; Barn;

   Sammanfattning : Föreliggande arbete är en kvalitativ studie som behandlar valet att bli förälder. Det som undersöks är svenska unga vuxnas samtal kring när tiden är rätt för att bli förälder, livet som förälder kontra livet utan barn, det ideala livet, det goda föräldraskapet och en bra barndom.

4. 3. Enabling Timing Analysis of Complex Embedded Software Systems

   Författare :Johan Kraft; Christer Norström; Anders Wall; Ian Broster; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded-systems; Real-time-systems; Timing-analysis; Simulation; Simulation-optimization; Simulation-Model-Extraction; Source-code-analysis; Run-time-monitoring; Model-validation; Computer science; Datavetenskap; Computer Science; datavetenskap;

   Sammanfattning : Cars, trains, trucks, telecom networks and industrial robots are examples of products relying on complex embedded software systems, running on embedded computers. Such systems may consist of millions of lines of program code developed by hundreds of engineers over many years, often decades. LÄS MER

5. 4. Preemption-Delay Aware Schedulability Analysis of Real-Time Systems

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

   Sammanfattning : 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. LÄS MER

7. 5. A WCET Analysis Method for Pipelined Microprocessors with Cache Memories

   Författare :Thomas Lundqvist; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; data cache; infeasible paths; pipeline; instruction cache; dynamically scheduled processor; worst-case execution time; timing analysis; path analysis; timing anomaly;

   Sammanfattning : When constructing real-time systems, safe and tight estimations of the worst case execution time (WCET) of programs are needed. To obtain tight estimations, a common approach is to do path and timing analyses. LÄS MER
