1. 16. Architectural Techniques for Improving Performance in Networks on Chip

   Författare :Mikael Millberg; Axel Jantsch; Marcello Coppola; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The main aim of this thesis is to propose enhancing techniques for the performance in Networks on Chips. In addition, a concrete proposal for a protocol stack within our NoC platform Nostrum is presented. Nostrum inherently supports both Best Effort as well as Guaranteed Throughput traffic delivery.

3. 17. The Impact of Application and Architecture Properties on Real-Time Multiprocessor Scheduling

   Författare :Jan Jonsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time scheduling; multiprocessor architectures; architecture properties; application properties; performance evaluation; predictability;

   Sammanfattning : Guaranteeing the temporal correctness of a real-time system is a very challenging problem since application and architecture properties may be hard to model accurately. For example, modern computer architectures are typically equipped with mechanisms, such as cache memories and instruction pipelines, whose behavior are by nature stochastic. LÄS MER

4. 18. Low-Power Multi-GHz Circuit Techniques for On-chip Clocking

   Författare :Martin Hansson; Atila Alvandpour; Per Larsson-Edefors; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; low-power; high-performance; flip-flop; clocking; leakage-compensation; process-variation; Electronics; Elektronik;

   Sammanfattning : The impressive evolution of modern high-performance microprocessors have resulted in chips with over one billion transistors as well as multi-GHz clock frequencies. As the silicon integrated circuit industry moves further into the nanometer regime, three of the main challenges to overcome in order for continuing CMOS technology scaling are; growing standby power dissipation, increasing variations in process parameters, and increasing power dissipation due to growing clock load and circuit complexity.

5. 19. Statistical Methods for Computational Markets : Proportional Share Market Prediction and Admission Control

   Författare :Thomas Sandholm; Magnus Boman; Mark Baker; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Grid Computing; Performance Analysis; Workload Modeling; Middleware; Quality of Service; Prediction; Admission Control; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : We design, implement and evaluate statistical methods for managing uncertainty when consuming and provisioning resources in a federated computational market. To enable efficient allocation of resources in this environment, providers need to know consumers' risk preferences, and the expected future demand. LÄS MER

7. 20. Analysis and Optimisation of Real-Time Systems with Stochastic Behaviour

   Författare :Sorin Manolache; Petru Eles; Zebo Peng; Xiaobo Hu; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Embedded systems; Real-time systems; System level design and optimisation; Stochastic execution times; Performance analysis; Networks-on-chip; Computer science; Datavetenskap;

   Sammanfattning : Embedded systems have become indispensable in our life: household appliances, cars, airplanes, power plant control systems, medical equipment, telecommunication systems, space technology, they all contain digital computing systems with dedicated functionality. Most of them, if not all, are real-time systems, i.e. LÄS MER
