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. Compression Techniques for Improved Bandwidth and Static Code Size in Computer Systems

   Författare :Martin Thuresson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; instruction decoding; data link compression; code compression; Computer architecture;

   Sammanfattning : Technological improvements in integrated circuits have for a longtime allowed the performance of computer chips to growexponentially, allowing for more and more advancedsystems. Unfortunately, the I/O-pins connecting the processorcore/cores with memory and other devices have not seen the samerate of improvement. LÄS MER

4. 3. Compression Techniques for Code Size and Data Bandwidth Reduction

   Författare :Martin Thuresson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; static code compression; high performance; Computer architecture; data link compression;

   Sammanfattning : A challenge in the design of high performance computer systems is how to transferdata efficiently between main memory and the faster and smaller memory located onthe processor chip. Main memory holds both the program to be executed and the datait needs to perform its tasks. LÄS MER

7. 5. Clinical and morphological aspects of metastatic spinal cord compression

   Författare :Johan Wänman; Sead Crnalic; Lukas Bobinski; Pawel Grabowski; Pernilla Wikström; Anders Bergh; Elin Thysell; Helena Brisby; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone metastasis; metastatic spinal cord compression; surgery for spinal metastases; Spinal Instability Neoplastic Score; prostate cancer; Orthopaedics; ortopedi; Orthopaedics; ortopedi;

   Sammanfattning : Background: Metastatic spinal cord compression (MSCC) is a serious complication of cancer leading to demyelination and axonal damage of the spinal cord with a risk of para/tetraplegia. It is most common in patients with known cancer but may also be the initial manifestation of malignancy (IMM). LÄS MER
