  • Scalability of broadcast performance in wireless network-on-chip 

    Abadal Cavallé, Sergi; Mestres Sugrañes, Albert; Nemirovsky, Mario; Lee, Heekwan; González Colás, Antonio María; Alarcón Cot, Eduardo José; Cabellos Aparicio, Alberto (2016-12-01)
    Article
    Accés obert
    Networks-on-Chip (NoCs) are currently the paradigm of choice to interconnect the cores of a chip multiprocessor. However, conventional NoCs may not suffice to fulfill the on-chip communication requirements of processors ...
  • Shared resource aware scheduling on power-constrained tiled many-core processors 

    Jha, Sudhanshu Shekhar; Heirman, Wim; Falcón Samper, Ayose Jesus; Tubella Murgadas, Jordi; González Colás, Antonio María; Eeckhout, Lieven (2017-02-01)
    Article
    Accés restringit per política de l'editorial
    Power management through dynamic core, cache and frequency adaptation is becoming a necessity in today’s power-constrained many-core environments. Unfortunately, as core count grows, the complexity of both the adaptation ...
  • Impact of parameter variations on circuits and microarchitecture 

    Unsal, Osman Sabri; Tschanz, James W.; Bowman, Keith; De, Vivek; Vera Rivera, Francisco Javier; González Colás, Antonio María; Ergin, Oguz (2006-12)
    Article
    Accés obert
    Parameter variations, which are increasing along with advances in process technologies, affect both timing and power. Variability must be considered at both the circuit and microarchitectural design levels to keep pace ...
  • Improving latency tolerance of multithreading through decoupling 

    Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (2001-10)
    Article
    Accés obert
    The increasing hardware complexity of dynamically scheduled superscalar processors may compromise the scalability of this organization to make an efficient use of future increases in transistor budget. SMT processors, ...
  • Hypercube algorithms on mesh connected multicomputers 

    Díaz de Cerio Ripalda, Luis Manuel; Valero García, Miguel; González Colás, Antonio María (2002-12)
    Article
    Accés obert
    A new methodology named CALMANT (CC-cube Algorithms on Meshes and Tori) for mapping a type of algorithm that we call CC-cube algorithm onto multicomputers with hypercube, mesh, or torus interconnection topology is proposed. ...
  • AGAMOS: A graph-based approach to modulo scheduling for clustered microarchitectures 

    Aleta Ortega, Alexandre; Codina Viñas, Josep M.; Sánchez Navarro, F. Jesús; González Colás, Antonio María; Kaeli, D (2009-06)
    Article
    Accés obert
    This paper presents AGAMOS, a technique to modulo schedule loops on clustered microarchitectures. The proposed scheme uses a multilevel graph partitioning strategy to distribute the workload among clusters and reduces the ...
  • An energy-efficient memory unit for clustered microarchitectures 

    Bieschewski, Stefan; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (2016-08-01)
    Article
    Accés obert
    Whereas clustered microarchitectures themselves have been extensively studied, the memory units for these clustered microarchitectures have received relatively little attention. This article discusses some of the inherent ...
  • Assisting static compiler vectorization with a speculative dynamic vectorizer in an HW/SW codesigned environment 

    Kumar, Rakesh; Martínez, Alejandro; González Colás, Antonio María (2016-01-01)
    Article
    Accés obert
    Compiler-based static vectorization is used widely to extract data-level parallelism from computation-intensive applications. Static vectorization is very effective in vectorizing traditional array-based applications. ...
  • A case for acoustic wave detectors for soft-errors 

    Upasani, Gaurang; Vera, Xavier; González Colás, Antonio María (2016-01-01)
    Article
    Accés restringit per política de l'editorial
    The continuing decrease in dimensions and operating voltage of transistors has increased their sensitivity against radiation phenomena, making soft errors an important challenge in future microprocessors. New techniques ...
  • Lifetime-sensitive modulo scheduling in a production environment 

    Llosa Espuny, José Francisco; Ayguadé Parra, Eduard; González Colás, Antonio María; Valero Cortés, Mateo; Eckhardt, Jason (2001-03)
    Article
    Accés restringit per política de l'editorial
    This paper presents a novel software pipelining approach, which is called Swing Modulo Scheduling (SMS). It generates schedules that are near optimal in terms of initiation interval, register requirements, and stage count. ...
