  1. 21. Techniques to Save Energy in Heterogeneous Multicore Architectures under QoS Constraints

    Författare :Muhammad Waqar Azhar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DVFS; Heterogeneous Multicores; Energy Efficiency; Resource Management; Core Migration; Quality-of-Service QoS ;

    Sammanfattning : Typically, applications are run with available system resources leading to over-provisioning of resources which can lead to high energy consumption. If the computational demand is specified, in terms of a Quality of Service (QoS) contract, it is possible to devote just enough resources to applications and thereby reduce energy consumption.

  3. 22. Storage-Centric System Architectures for Networked, Resource-Constrained Devices

    Författare :Nicolas Tsiftes; Thiemo Voigt; Per Gunningberg; Chenyang Lu; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Internet of Things; wireless sensor networks; resource-constrained devices; file system; database management system; virtual machine; data compression; reprogramming; checkpointing; Datavetenskap; Computer Science;

    Sammanfattning : The emergence of the Internet of Things (IoT) has increased the demand for networked, resource-constrained devices tremendously. Many of the devices used for IoT applications are designed to be resource-constrained, as they typically must be small, inexpensive, and powered by batteries. LÄS MER

  4. 23. Programming of coarse-grained reconfigurable architectures

    Författare :Zain Ul-Abdin; Bertil Svensson; Veronica Gaspes; Dag Stranneby; Mario Porrmann; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY; TEKNIKVETENSKAP; Computer science; Datavetenskap; Datalogi; Computer and Systems Science;

    Sammanfattning : Coarse-grained reconfigurable architectures, which offer massive parallelism coupled with the capability of undergoing run-time reconfiguration, are gaining attention in order to meet not only the increased computational demands of high-performance embedded systems, but also to fulfill the need of adaptability to functional requirements of the application. This thesis focuses on the programming aspects of such coarse-grained reconfigurable computing devices, including the relevant computation models that are capable of exposing different kinds of parallelism inherent in the application and the ability of these models to capture the adaptability requirements of the application.

  5. 24. Self-Reliance for the Internet of Things: Blockchains and Deep Learning on Low-Power IoT Devices

    Författare :Christos Profentzas; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Deep Neural Networks; Blockchain; Smart Contracts; Internet of Things; TinyML;

    Sammanfattning : The rise of the Internet of Things (IoT) has transformed common embedded devices from isolated objects to interconnected devices, allowing multiple applications for smart cities, smart logistics, and digital health, to name but a few. These Internet-enabled embedded devices have sensors and actuators interacting in the real world. LÄS MER

  7. 25. Three Specialized Computer Architectures for Functional Program Execution

    Författare :Jonas Vasell; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; computer architectures; G-machine; programming languages; program compilation techniques; VLSI implementation; performance; array architecture;

    Sammanfattning : Functional programming languages offer a new programming paradigm with many advantages over the more conventional imperative or procedural programming languages. However, these new languages are not as well adapted to the existing computers as the conventional languages, which results in low performance. LÄS MER
