  1. 16. Graceful Degradation of Adaptive Multiprocessor Systems on a Chip

    Författare :Stavros Tzilis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design space exploration; runtime management; graceful degradation; system optimization; Defect and fault tolerance;

    Sammanfattning : This thesis explores the potential for using existing flexibility in order to allow Multiprocessor Systems on a Chip to function in the presence of permanent faults and to prolong their lifetime. Technology scaling in accordancewith Moore’s law brings up reliability challenges and forces the use of potentially unreliable hardware components. LÄS MER

  3. 17. Towards Low-Complexity Scalable Shared-Memory Architectures

    Författare :Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

    Sammanfattning : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. LÄS MER

  4. 18. Strategies to Reduce Energy and Resources in Chip Multiprocessor Systems

    Författare :Magnus Ekman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : A new architectural style known as chip multiprocessor (CMP) has recently emerged, where two or more processor cores are manufactured on the same die. This architectural style comes with many promises such as high performance for applications with much thread-level parallelism (TLP) and shorter design times due to its modularized design. LÄS MER

  5. 19. New Techniques for Building Timing-Predictable Embedded Systems

    Författare :Nan Guan; Wang Yi; Lothar Thiele; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; WCET analysis; cache analysis; abstract interpretation; multiprocessor scheduling; fixed-priority scheduling; EDF; multi-core processors; response time analysis; utilization bound; real-time calculus; scalability; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Sammanfattning : Embedded systems are becoming ubiquitous in our daily life. Due to close interaction with physical world, embedded systems are typically subject to timing constraints. At design time, it must be ensured that the run-time behaviors of such systems satisfy the pre-specified timing constraints under any circumstance. LÄS MER

  7. 20. Techniques to Improve Energy Efficiency on Heterogeneous Multiprocessors under Timing and Quality Constraints

    Författare :Muhammad Waqar Azhar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thread throttling; Energy Efficiency; Dynamic Voltage Frequency Scaling DVFS ; Quality of Service; Heterogeneous multiprocessor; Soft real time systems.; Resource management; Core migration;

    Sammanfattning : Traditionally, applications are executed without the notion of a computational deadline and often use all available system resources, which leads to higher energy consumption. User specification of Quality of Service (QoS) constraints, in terms of completion time and solution quality, opens up for allocation of just enough resources to an application to finish just in time and thereby save energy.
