  1. 11. Dynamically Reconfigurable Architectures for Real-time Baseband Processing

    Författare :Chenxin Zhang; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable Computing; Coarse-Grained Architecture; Dynamic Reconfiguration; SIMD; VLIW; ASIP; Vector Processor; Baseband Processing; OFDM; MIMO; Channel Estimation; Symbol Detection.;

    Sammanfattning : Motivated by challenges from today's fast-evolving wireless communication standards and soaring silicon design cost, it is important to design a flexible hardware platform that can be dynamically reconfigured to adapt to current operating scenarios, provide seamless handover between different communication networks, and extend the longevity of advanced systems. Moreover, increasingly sophisticated baseband processing algorithms pose stringent requirements of real-time processing for hardware implementations, especially for power-budget limited mobile terminals.

  3. 12. Optimizing Fault Tolerance for Real-Time Systems

    Författare :Dimitar Nikolov; Erik Larsson; Elena A. Troubitsyna; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : For the vast majority of computer systems correct operation is defined as producing the correct result within a time constraint (deadline). We refer to such computer systems as real-time systems (RTSs). LÄS MER

  4. 13. Size Estimation of Real-Time Software Components - A System Perspective

    Författare :Kenneth Lind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; COSMIC Function Points; software code size; Functional Size Measurement; software components; system architecture.;

    Sammanfattning : The demands and expectations on the system architectures of contemporary consumer products like cars are increasing for each product generation. New features using new sensors and actuators, with different variants on different markets, and that interact with other features, create additional complexity in the system. LÄS MER

  5. 14. Adaptive Real-time Monitoring for Large-scale Networked Systems

    Författare :Alberto Gonzalez Prieto; Rolf Stadler; George Pavlou; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Large-scale networked systems, such as the Internet and server clusters, are omnipresent today. They increasingly deliver services that are critical to both businesses and the society at large, and therefore their continuous and correct operation must be guaranteed. LÄS MER

  7. 15. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications

    Författare :Petros Voudouris; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling; Multiprocessor; WCET; Uniform; Hard; multicore; Related; DAG; Real-Time; Dynamic; Unrelated; Makespan; Homogeneous; Parallel; Identical;

    Sammanfattning : To use multiprocessors in hard real-time systems, schedulability analysis is needed to provide formally proven guarantees for the timing behavior of the system. Programming models for parallel applications, such as OpenMP, use pragmas to specify parts of the application as parallel tasks, for example, a function or a body of a loop. LÄS MER
