    Abstract : Wireless communication is a key enabler for connecting billions of Internet of Things devices. For networked embedded devices operating on limited energy resources, wireless communication dominates the power consumption. READ MORE

  4. 2. Rethinking Dynamic Instruction Scheduling and Retirement for Efficient Microarchitectures

    Author : Mehdi Alipour; David Black-Schaffer; Stefanos Kaxiras; Mikko H. Lipasti; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Out-of-Order Processors; Energy-Efficient; High-Performance; Instruction Scheduling; Computer Science; Datavetenskap;

    Abstract : Out-of-order execution is one of the main micro-architectural techniques used to improve the performance of both single- and multi-threaded processors. The application of such a processor varies from mobile devices to server computers. READ MORE

  5. 3. Optimizing Performance in Highly Utilized Multicores with Intelligent Prefetching

    Author : Muneeb Khan; Erik Hagersten; David Black-Schaffer; Bengt Jonsson; Per Stenström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Performance; Optimization; Prefetching; multicore; memory hierarchy; Computer Science; Datavetenskap;

    Abstract : Modern processors apply sophisticated techniques, such as deep cache hierarchies and hardware prefetching, to increase performance. Such complex hardware structures have helped improve performance in general, however, their full potential is not realized as software often utilizes the memory hierarchy inefficiently. READ MORE

  6. 4. Seamless Integration of Battery-Free Communications in Commodity Wireless Networks

    Author : Carlos Pérez-Penichet; Thiemo Voigt; Frederik Hermans; James Gross; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Backscatter communications; battery-free communications; battery-less devices; RFID; backscatter;

    Abstract : Ubiquitous sensing applications have countless potential benefits to society. However, batteries have long been an obstacle to their full development. Harvesting energy from the environment is a promising alternative to battery power, but traditional radio transceivers consume too much for most harvesters. READ MORE

  7. 5. Improving Energy-Efficiency of Multicores using First-Order Modeling

    Author : Vasileios Spiliopoulos; Stefanos Kaxiras; Lieven Eeckhout; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; DVFS; Cache Resizing; Interval modeling; Power modeling; Computer Science; Datavetenskap;

    Abstract : In the recent decades, power consumption has evolved to one of the most critical resources in a computer system. In the form of electricity bill in data centers, battery life in mobile devices, or thermal constraints in desktops and laptops, power consumption imposes several limitations in today’s processors and improving power and energy efficiency is one of the most urgent research topics of Computer Architecture.
