1. 36. Low-Power Multi-GHz Circuit Techniques for On-chip Clocking

   Författare :Martin Hansson; Atila Alvandpour; Per Larsson-Edefors; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; low-power; high-performance; flip-flop; clocking; leakage-compensation; process-variation; Electronics; Elektronik;

   Sammanfattning : The impressive evolution of modern high-performance microprocessors have resulted in chips with over one billion transistors as well as multi-GHz clock frequencies. As the silicon integrated circuit industry moves further into the nanometer regime, three of the main challenges to overcome in order for continuing CMOS technology scaling are; growing standby power dissipation, increasing variations in process parameters, and increasing power dissipation due to growing clock load and circuit complexity.

3. 37. Exploring Massively Parallel Models and Architectures for Efficient Computation of Evolutionary Algorithms

   Författare :Sven Eklund; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; distributed population models; evolutionary algorithms; symbolic function regression; genetic programming; linear machine code; Diffusion Model; time series forecasting; FPGA; VHDL;

   Sammanfattning : 'Evolutionary algorithms' is the collective name for a group of relatively new stochastic search algorithms that have several unique and interesting properties. However, as with all search algorithms, evolutionary algorithms also have disadvantages. LÄS MER

4. 38. Aspects of system-on-chip design for FPGAs

   Författare :Andreas Ehliar; Lars Svensson; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : Due to the increasing NRE costs of recent ASICs, the use of FPGAs is expected to continue to increase. While the first FPGAs were limited devices useful mainly for glue logic, todays FPGAs are highly capable devices used in many different application areas including telecommunication, multimedia, medical, and automotive.

5. 39. Multidimensional Piecewise Regular Arrays

   Författare :Toomas P. Plaks; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polytopes; commutativity; systolic arrays; associativity; space-time mapping; piecewise regular arrays;

   Sammanfattning : Regular arrays, particularly systolic arrays, have been the subject of continuous interest for the past 15 years. One reason is that they present an excellent example of the unity between hardware and software, especially for application-specific computations. LÄS MER

7. 40. Controllable Multi-dimensional Filters and Models in Low-Level Computer Vision

   Författare :Mats T. Andersson; Gösta Granlund; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This thesis concerns robust estimation of low-level features for use in computer vision systems. The presentation consists of two parts.The first part deals with controllable filters and models. A basis filter set is introduced which supports a computationally efficient synthesis of filters in arbitrary orientations. LÄS MER
