    • Accelerating Halide on an FPGA 

      Granell Escalfet, Sergi (Universitat Politècnica de Catalunya, 2023-05-15)
      Projecte Final de Màster Oficial
      Accés obert
      Realitzat a/amb:   Kyūshū Daigaku
      Image processing and, more generally, array processing play an essential role in modern life: from applying filters to the images that we upload to social media to running object detection algorithms on self-driving cars. ...

    • Computing size-independent matrix problems on systolic array processors 

      Navarro Guerrero, Juan José; Llaberia Griñó, José M.; Valero Cortés, Mateo (1985)
      Report de recerca
      Accés obert
      A methodology to transform dense to banded matrices is presented in this paper. This transformation, is accomplished by triangular blocks partitioning, and allows the implementation of silutions to problems with any given ...

    • Estudio del impacto del formato de almacenamiento sobre el rendimiento de la operación matriz dispersa por vector 

      Pasarín Soler, Marc (Universitat Politècnica de Catalunya, 2010-11)
      Projecte/Treball Final de Carrera
      Accés obert
      El objetivo principal de este proyecto es estudiar diversos formatos de almacenamiento para matrices dispersas de forma que se permita un mejor rendimiento de la operación SpMV en arquitecturas multicore, como son las ...

    • Hierarchical stack filtering: a bitplane-based algorithm for massively parallel processors 

      Frías Velazquez, Andres; Morros Rubió, Josep Ramon; García Molina, Mario; Philips, Wilfried (2019-10)
      Article
      Accés obert
      With the development of novel parallel architectures for image processing, the implementation of well-known image operators needs to be reformulated to take advantage of the so-called massive parallelism. In this work, we ...

    • Multi-antenna 3D pattern design for millimeter-wave vehicular communications 

      Ballesteros Sánchez, Christian; Montero Bayo, Luca; Ramírez Arroyave, Germán Augusto; Jofre Roca, Lluís (Elsevier, 2022-06)
      Article
      Accés obert
      The transformation of the automotive industry towards ubiquitous connection of vehicles with all kind of external agents (V2X) motivates the use of a wide range of frequencies for several applications. Millimeter-wave ...

    • On the classification of self-triggered versus other-triggered lightning flashes 

      Sunjerga, A.; Mostajabi, A.; Pineda Rüegg, Nicolau; Romero Durán, David; Van der Velde, Oscar Arnoud; Montanya, Joan; Azadifar, M.; Rubinstein, M.; Diendorfer, Gergard (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      We present in this paper lightning current measurements and LMA (Lightning Mapping Array) data associated with upward flashes observed at the Sàntis Tower during Summer 2017. The LMA network consists of six stations located ...

    • Real-time 3D multi-person tracking using Monte Carlo surface sampling 

      Canton Ferrer, Cristian; Casas Pla, Josep Ramon; Pardàs Feliu, Montse (2010)
      Text en actes de congrés
      Accés obert
      The current paper presents a low-complexity approach to the problem of simultaneous tracking of several people in low resolution sequences from multiple calibrated cameras. Redundancy among cameras is exploited to ...

    • Solving matrix problems with no size restriction on a systolic array processor 

      Navarro Guerrero, Juan José; Llaberia Griñó, José M.; Valero Cortés, Mateo (1986)
      Report de recerca
      Accés obert
      In this paper we propose several data structures partitioning and transformation schemes, in order to get an efficient execution of various matrix algorithms without any size resriction. The following matrix operations are ...
