  1. 1. Statistical Compression Cache Designs

    Författare :Angelos Arelakis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cache; Floating-point compression; Data Compression; Huffman Coding; Statistical Compression; Value Locality; Memory; Hybrid Compression;

    Sammanfattning : On-chip caches are essential as they bridge the growing speed-gap between off-chip memory and processors. To this end, processing cores are sacrificed for more cache space in the chip's real estate, possibly affecting the cache access time and power dissipation. LÄS MER

  3. 2. Reducing Memory Traffic with Approximate Compression

    Författare :Albin Eldstål-Ahrens; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory Compression; Memory Systems; Compression; Computer Architecture; Lossy Compression; Approximate Computing;

    Sammanfattning : Memory bandwidth is a critical resource in modern systems and has an increasing demand. The large number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates. In addition, new emerging data-intensive applications further increase memory traffic. LÄS MER

  4. 3. Wood fibre deformation in combined shear and compression

    Författare :Federica De Magistris; Anders Eriksson; Ola Dahlblom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arcan; compression; density; energy; finite element analysis; Iosipescu; Picea abies; shear; wood; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : Mechanical pulping for producing pulps from softwood suitable for printing grade papers, like news, is a highly energy-intensive process consuming around 2000 kWh/t in electrical energy. Due to increasing energy costs and environmental issues there is a high demand for decreasing this energy consumption. LÄS MER

  5. 4. Lossy and Lossless Compression Techniques to Improve the Utilization of Memory Bandwidth and Capacity

    Författare :Albin Eldstål-Ahrens; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Approximate Computing; Compression; Memory Systems;

    Sammanfattning : Main memory is a critical resource in modern computer systems and is in increasing demand. An increasing number of on-chip cores and specialized accelerators improves the potential processing throughput but also calls for higher data rates and greater memory capacity. LÄS MER

  7. 5. Compression Mechanics of Powders and Granular Materials Probed by Force Distributions and a Micromechanically Based Compaction Equation

    Författare :Foad Mahmoodi; Göran Frenning; Bruno Hancock; Uppsala universitet; []
    Nyckelord :compression; powder; mechanical properties; pellet; tablet; compaction equation; force distribution;

    Sammanfattning : The internal dynamics of powder systems under compression are as of yet not fully understood, and thus there is a necessity for approaches that can help in further clarifying and enhancing the level of understanding on this subject. To this end, the internal dynamics of powder systems under compression were probed by means of force distributions and a novel compaction equation. LÄS MER
