    Developing parallel applications that can harness and efficiently use future many-core architectures is the key challenge for scalable computing systems. We contribute to this challenge by presenting a parallel implementation ...
  • Parallel H.264 decoding on an embedded multicore processor 

    Azevedo, Arnaldo; Meenderinck, Cor; Juurlink, Ben; Terechko, Andrei; Hoogerbrugge, Jan; Álvarez Mesa, Mauricio; Ramírez Bellido, Alejandro (Springer-Verlag, Berlin, Heidelberg,, 2009-01-28)
    Conference report

    In previous work the 3D-Wave parallelization strategy was proposed to increase the parallel scalability of H.264 video decoding. This strategy is based on the observation that inter-frame dependencies have a limited spatial ...
  • Parallel scalability of video decoders 

    Meenderinck, Cor; Azevedo, Arnaldo; Juurlink, Ben; Álvarez Mesa, Mauricio; Ramírez Bellido, Alejandro (2009-11)
    Article
    Restricted access - publisher's policy
    An important question is whether emerging and future applications exhibit sufficient parallelism, in particular thread-level parallelism, to exploit the large numbers of cores future chip multiprocessors (CMPs) are ...
  • Performance evaluation of macroblock-level parallelization of H.264 decoding on a cc-NUMA multiprocessor architecture 

    Álvarez Mesa, Mauricio; Ramírez Bellido, Alejandro; Valero Cortés, Mateo; Azevedo, Arnaldo; Meenderinck, Cor; Juurlink, Ben (2009-04-23)
    Conference report

  • Scalability of Macroblock-level parallelism for H.264 decoding 

    Álvarez Mesa, Mauricio; Ramírez Bellido, Alejandro; Azevedo, Arnaldo; Meenderinck, Cor; Juurlink, Ben; Valero Cortés, Mateo (IEEE Computer Society Publications, 2009-12-11)
    Conference report
    Open Access
    This paper investigates the scalability of MacroBlock(MB) level parallelization of the H.264 decoder for High Definition (HD) applications. The study includes three parts. First, a formal model for predicting the maximum ...
  • The SARC architecture 

    Gaydadjiev, Georgi; Isaza, Sebastian; Ramírez Bellido, Alejandro; Cabarcas, Felipe; Juurlink, Ben; Álvarez Mesa, Mauricio; Sánchez Castaño, Friman; Azevedo, Arnaldo; Meenderinck, Cor; Ciobanu, Catalin (2010-10)
    Article
    Open Access
    The SARC architecture is composed of multiple processor types and a set of user-managed direct memory access (DMA) engines that let the runtime scheduler overlap data transfer and computation. The runtime system automatically ...
