  1. 16. Securing concurrent programs with dynamic information-flow control

    Författare :Pablo Buiras; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dynamic; lazy evaluation; LIO; Haskell; information-flow control; cache; covert channels; covert timing channels; concurrency;

    Sammanfattning : The work presented in this thesis focusses on dealing with timingcovert channels in dynamic information-flow control systems,particularly for the LIO library in Haskell.Timing channels are dangerous in the presence ofconcurrency. LÄS MER

  3. 17. A dynamic programming approach to optimal retargetable code generation for irregular architectures

    Författare :Andrzej Bednarski; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Sammanfattning : In this thesis we address the problem of optimal code generation for irregular architectures such as Digital Signal Processors (DSPs). Code generation consists mainly of three tasks: instruction selection, instruction scheduling and register allocation. LÄS MER

  4. 18. Embedded Languages for Data-Parallel Programming

    Författare :Joel Bo Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphics Processing Units; Data-parallelism; Functional Programming; Embedded languages;

    Sammanfattning : Computers today are becoming more and more parallel. General purpose processors (CPUs) have multiple processing cores and Single Instruction Multiple Data (SIMD) units for data-parallelism. Graphics processors (GPUs) bring massive parallelism at the cost of being harder to program than CPUs. LÄS MER

  5. 19. Design of Energy-Efficient High-Performance ASIP-DSP Platforms

    Författare :Andréas Karlsson; Dake Liu; Andreas Ehliar; Jarmo Takala; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the last ten years, limited clock frequency scaling and increasing power density has shifted IC design focus towards parallelism, heterogeneity and energy efficiency. Improving energy efficiency is by no means simple and it calls for a reevaluation of old design choices in processor architecture, and perhaps more importantly, development of new programming methodologies that exploit the features of modern architectures.

  7. 20. Escaping 'death by GPS' : foundations for adaptive navigation assistance

    Författare :Fateme Teimouri; Kai-Florian Richter; Henrik Björklund; Sabine Timpf; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wayfinding; navigation systems; navigation complexity; prominent locations; route generalization; spatial cognition; mental models; route learning; direction giving; Human-centered study.;

    Sammanfattning : Navigating through physical environments has evolved over time from using stars and maps to support the wayfinding, to employing Global Positioning Systems and navigation services. Turn-by-turn guidance of navigation services is an effective way to support wayfinding, but it may not align with the way humans naturally navigate. LÄS MER
