    Cross-layer reliability is becoming the preferred solution when reliability is a concern in the design of a microprocessor-based system. Nevertheless, deciding how to distribute the error management across the different ...
  • 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 ...
  • Testing the performance of sensors for ozone pollution monitoring in a citizen science approach 

    Ripoll Ruiz, Aleix; Viana, Mar; Padrosa, Marc; Querol Carceller, Xavier; Minutolo, Andrea; Hou, Kun Mean; Barceló Ordinas, José María; García Vidal, Jorge (Elsevier, 2019-02-15)
    Article
    Accés obert
    Tropospheric ozone (O3) is an environmental pollutant of growing concern, especially in suburban and rural areas where the density of air quality monitoring stations is not high. In this type of areas citizen science ...
  • Learning from the optical spectrum: failure detection and identification [Invited] 

    Behnam Shariati, Mohammad; Ruiz Ramírez, Marc; Comellas Colomé, Jaume; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2018-07-23)
    Article
    Accés obert
    The availability of coarse-resolution cost-effective Optical Spectrum Analyzers (OSA) allows its widespread deployment in operators’ networks. In this paper, we explore several machine learning approaches for soft-failure ...
  • Machine learning for network automation: Overview, architecture, and applications [invited tutorial] 

    Rafique, Danish; Velasco Esteban, Luis Domingo (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    Article
    Accés obert
    Networks are complex interacting systems involving cloud operations, core and metro transport, and mobile connectivity all the way to video streaming and similar user applications. With localized and highly engineered ...
  • 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 ...
