  2. 6. 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. 7. Static Timing Analysis of Parallel Systems Using Abstract Execution

    Author : Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; Nan Guan; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

    Abstract : The Power Wall has stopped the past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism.Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. READ MORE

  5. 8. Timing Analysis of Distributed Embedded Systems with Stochastic Workload and Realiability Constraints

    Author : Bogdan Tanasa; Petru Eles; Zebo Peng; Unmesh Dutta Bordoloi; Lucia Lo Bello; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; embedded systems; perfomance analysis; real-time systems; distributed systems; fault tolerance; probabilistic analysis;

    Abstract : Today's distributed embedded systems are exposed to large variations in workload due to complex software applications and sophisticated hardware platforms. Examples of such systems are automotive and avionics applications.The tasks running on computational units have variable execution times. READ MORE

    Abstract : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. READ MORE

  7. 10. On the Design and Analysis of Consensus Protocols for Automotive Electronic Systems

    Author : Negin Fathollah Nejad Asl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication Failures; Consensus; Distributed Algorithms; Automotive Systems; Probabilistic Analysis;

    Abstract : This thesis deals with the fundamental problem of reaching agreement on a value in a distributedcomputing system in the presence of faults. We address this problem in the contextof safety-critical distributed automotive applications, such as virtual traffic lights. READ MORE
