    Article
    Accés obert
    The recent upsurge in the available amount of health data and the advances in next-generation sequencing are setting the ground for the long-awaited precision medicine. To process this deluge of data, bioinformatics workloads ...
  • Symbolic analysis of bounded Petri nets 

    Pastor Llorens, Enric; Cortadella, Jordi; Roig Mansilla, Oriol (Institute of Electrical and Electronics Engineers (IEEE), 2001-05)
    Article
    Accés obert
    This paper presents a symbolic approach for the analysis of bounded Petri nets. The structure and behavior of the Petri net is symbolically modeled by using Boolean functions, thus reducing reasoning about Petri nets to ...
  • Decomposition and technology mapping of speed-independent circuits using Boolean relations 

    Cortadella, Jordi; Kishinevsky, Michael; Kondratyev, Alex; Lavagno, Luciano; Pastor Llorens, Enric; Yakovlev, Alex (1999-09)
    Article
    Accés obert
    This paper presents a new technique for decomposition and technology mapping of speed-independent circuits. An initial circuit implementation is obtained in the form of a netlist of complex gates, which may not be available ...
  • Auto-tuned OpenCL kernel co-execution in OmpSs for heterogeneous systems 

    Pérez, Borja; Stafford, Esteban; Bosque Orero, José Luis; Beivide Palacio, Ramon; Mateo Bellido, Sergi; Teruel García, Xavier; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (2019-03-01)
    Article
    Accés obert
    The emergence of heterogeneous systems has been very notable recently. The nodes of the most powerful computers integrate several compute accelerators, like GPUs. Profiting from such node configurations is not a trivial ...
  • Structural methods for the synthesis of speed-independent circuits 

    Pastor Llorens, Enric; Cortadella, Jordi; Kondratyev, Alex; Roig Mansilla, Oriol (1998-11)
    Article
    Accés obert
    Asynchronous circuits can be modeled as concurrent systems in which events are interpreted as signal transitions. The synthesis of concurrent systems implies the analysis of a vast state space that often requires computationally ...
  • Towards mobile cloud computing with single sign-on access 

    Lordan Gomis, Francesc-Josep; Jensen, J. K.; Badia Sala, Rosa Maria (2017-10-30)
    Article
    Accés obert
    The low computing power of mobile devices impedes the development of mobile applications with a heavy computing load. Mobile Cloud Computing (MCC) has emerged as the solution to this by connecting mobile devices with the ...
  • Evaluation of A+B=K conditions without carry propagation 

    Cortadella, Jordi; Llaberia Griñó, José M. (Institute of Electrical and Electronics Engineers (IEEE), 1992-11)
    Article
    Accés obert
    The response time of parallel adders is mainly determined by the carry propagation delay. The evaluation of conditions of the type A+B=K is addressed. Although an addition is involved in the comparison, it is shown that ...
  • Constant-time sliding window framework with reduced memory footprint and efficient bulk evictions 

    Villalba Navarro, Álvaro; Berral García, Josep Lluís; Carrera Pérez, David (2018-09-06)
    Article
    Accés obert
    The fast evolution of data analytics platforms has resulted in an increasing demand for real-time data stream processing. From Internet of Things applications to the monitoring of telemetry generated in large data centers, ...
