2. 1. Synchoros VLSI Design Style

   Author : Dimitrios Stathis; Ahmed Hemani; Anders Lansner; Christian Weis; Dimitrios Soudris; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VLSI; ASIC; CGRA; hardware architectures; synchoros VLSI; SiLago; eBrain; BCPNN; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Computers have become essential to everyday life as much as electricity, communications and transport. That is evident from the amount of electricity we spend to power our computing systems. According to some reports it is estimated to be ≈ 7% of the total consumption worldwide. READ MORE

4. 2. Dynamically Reconfigurable Resource Array

   Author : Muhammad Ali Shami; Ahmed Hemani; S.K Nandy; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DRRA; CGRA; FPGA; VLSI; ASIC; Embedded systems; Coarse grain reconfigurable architecture; reconfigurable computing;

   Abstract : The goals set by the International Technology Roadmap for Semiconductors (ITRS) for the consumer portable category, to be realized by 2020, are 1000X improvement in performance with only 40\% increase in power budget and no increase in design team size. To meet these goals, the challenges facing the VLSI community are gaps in architecture efficacy, design productivity and battery capacity. READ MORE

5. 3. A Segmented Silicon Strip Detector for Photon-Counting Spectral Computed Tomography

   Author : Cheng Xu; Hans Bornefalk; Mats Danielsson; Ami Altman; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; photon counting; spectral computed tomography; silicon strip detector; ASIC; energy resolution; cadmium telluride; charge sharing; Monte Carlo simulation; synchrotron;

   Abstract : Spectral computed tomography with energy-resolving detectors has a potential to improve the detectability of images and correspondingly reduce the radiation dose to patients by extracting and properly using the energy information in the broad x-ray spectrum. A silicon photon-counting detector has been developed for spectral CT and it has successfully solved the problem of high photon flux in clinical CT applications by adopting the segmented detector structure and operating the detector in edge-on geometry.

6. 4. Cross-Correlator Implementations Enabling Aperture Synthesis for Geostationary-Based Remote Sensing

   Author : Erik J Ryman; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-custom; signal processing; synthetic aperture; Cross-correlation; interferometric imaging; ASIC; remote sensing;

   Abstract : An ever-increasing demand for weather prediction and high climate modelling accuracy drives the need for better atmospheric data collection. These demands include better spatial and temporal coverage of mainly humidity and temperature distributions in the atmosphere. READ MORE

7. 5. Techniques for Efficient Implementation of FIR and Particle Filtering

   Author : Syed Asad Alam; Oscar Gustafsson; Kent Palmkvist; Yajun Yu; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; FIR filter; Particle filter; architecture; ASIC; FPGA;

   Abstract : FIR filters occupy a central place many signal processing applications which either alter the shape, frequency or the sampling frequency of the signal. FIR filters are used because of their stability and possibility to have linear-phase but require a high filter order to achieve the same magnitude specifications as compared to IIR filters. READ MORE
