  2. 1. Approximation and Compression Techniques to Enhance Performance of Graphics Processing Units

    Author : Alexandra Angerd; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compression; Approximate Computing; Register File; Machine Learning; Floating-Point Precision; Microarchitecture; GPU;

    Abstract : A key challenge in modern computing systems is to access data fast enough to fully utilize the computing elements in the chip. In Graphics Processing Units (GPUs), the performance is often constrained by register file size, memory bandwidth, and the capacity of the main memory. READ MORE

  4. 2. Performance and Energy Efficient Building Blocks for Network-on-Chip Architectures

    Author : Sriram R. Vangal; Atila Alvandpour; Viktor Öwall; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Network-on-Chip Architectures; floating-point units; tiled-architectures; crossbar routers; multi-processor interconnection; Computer engineering; Datorteknik;

    Abstract : The ever shrinking size of the MOS transistors brings the promise of scalable Network-on-Chip (NoC) architectures containing hundreds of processing elements with on-chip communication, all integrated into a single die. Such a computational fabric will provide high levels of performance in an energy efficient manner. READ MORE

  5. 3. An Automated and Controlled Numerical Precision Reduction Framework for GPUs

    Author : Alexandra Angerd; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microarchitecture; Floating-Point Precision; Approximate Computing; Register File; GPU;

    Abstract : Reducing the precision of floating-point values is an effective approach to achieve higher performance as well as higher energy-efficiency. This is especially true for GPUs, since many of its common tasks are inherently insensitive to precision-reduction. READ MORE

    Abstract : Filtering is a fundamental operation in image science in general and in medical image science in particular. The most central applications are image enhancement, registration, segmentation and feature extraction. READ MORE

  7. 5. Performance and Energy Efficient Network-on-Chip Architectures

    Author : Sriram Vangal; Atila Alvandpour; Wim Dehaene; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chips; MOS transistors; Network-on-Chip NoC ; process technology; FPMAC; Electrical engineering; Elektroteknik;

    Abstract : The scaling of MOS transistors into the nanometer regime opens the possibility for creating large Network-on-Chip (NoC) architectures containing hundreds of integrated processing elements with on-chip communication. NoC architectures, with structured on-chip networks are emerging as a scalable and modular solution to global communications within large systems-on-chip. READ MORE
