  2. 1. System Design for DSP Applications with the MASIC Methodology

    Author : Abhijit Kumar Deb; KTH; []
    Keywords : System design methodology; Signal processing systems; Design decision; Communication; Computation; Model development; Transaction level model; System design language; Grammar; MASIC.;

    Abstract : The difficulties of system design are persistentlyincreasing due to the integration of more functionality on asystem, time-to-market pressure, productivity gap, andperformance requirements. To address the system designproblems, design methodologies build system models at higherabstraction level. READ MORE

  4. 2. Reconfigurable Architectures for Embedded Systems

    Author : Henrik Svensson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reconfigurable Architectures; Run-time Reconfiguration; Reconfigurable Computing; Embedded Systems; System Level Modeling; Design Exploration;

    Abstract : Application-specific circuits are used to migrate computer systems from workstations to handheld devices that need real-time performance within the budget for physical size and energy dissipation. However, these circuits are inflexible as any modification requires redesign and refabrication, which is both expensive and time-consuming considering the complexity of recent embedded platforms.

  5. 3. Scaling Distributed Hierarchical File Systems Using NewSQL Databases

    Author : Salman Niazi; Jim Dowling; Seif Haridi; Seif Haridi; Rui Oliveira; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : For many years, researchers have investigated the use of database technology to manage file system metadata, with the goal of providing extensible typed metadata and support for fast, rich metadata search. However, earlier attempts failed mainly due to the reduced performance introduced by adding database operations to the file system’s critical path. READ MORE

  6. 4. Virtual Full Replication for Scalable Distributed Real-Time Databases

    Author : Gunnar Mathiason; Sten F. Andler; Sang H. Son; Hans Hansson; Alejandro Buchmann; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database; Computer science; Datalogi; Information technology; Informationsteknik; Teknik;

    Abstract : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

  7. 5. Towards Accurate and Resource-Efficient Cache Coherence Prediction

    Author : Jim Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cache coherence protocols; performance evaluation; computer architecture; memory systems; shared memory multiprocessors;

    Abstract : The increasing speed gap between processor microarchitectures and memory technologies can potentially slow down the historical performance growth of computer systems. Parallel applicationns on shared memory multiprocessors that experience cache misses due to communication are extra susceptible to this speed difference. READ MORE
