    General purpose computer designers have recently begun adding cores to their processors in order to increase performance. For example, Intel has adopted a homogeneous quad-core processor as a base for general purpose ...
  • Implementing a hybrid SRAM / eDRAM NUCA architecture 

    Lira Rueda, Javier; Molina Clemente, Carlos; Brooks, David; González Colás, Antonio María (2010-08-27)
    External research report
    Open Access
    In this paper, we propose a hybrid cache architecture that exploits the main features of both memory technologies, speed of SRAM and high density of eDRAM. We demonstrate, that due to the high locality found in emerging ...
  • Improving the prefetching performance through code region profiling 

    Torrents Lapuerta, Martí; Martínez, Raul; Molina Clemente, Carlos (Barcelona Supercomputing Center, 2015-05-05)
    Conference report
    Open Access
    In this work, we propose a new technique to improve the performance of hardware data prefetching. This technique is based on detecting periods of time and regions of code where the prefetcher is not working properly, ...
  • Last Bank: dealing with address reuse in non-uniform cache architecture for CMPs 

    Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (2009-01-16)
    External research report
    Open Access
    In response to the constant increase in wire delays, Non-Uniform Cache Architecture (NUCA) has been introduced as an effective memory model for dealing with growing memory latencies. This architecture divides a large memory ...
  • LRU-PEA: A smart replacement policy for non-uniform cache architectures on chip multiprocessors 

    Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (2009-05-14)
    External research report
    Open Access
    The increasing speed-gap between processor and memory and the limited memory bandwidth make last-level cache performance crucial for CMP architectures. Non Uniform Cache Architectures (NUCA) has been introduced to deal ...
  • Microarchitectural Techniques to Exploit Repetitive Computations and Values 

    Molina Clemente, Carlos (Universitat Politècnica de Catalunya, 2005-07-10)
    Doctoral thesis
  • OLSRp: predicting control information to achieve scalability in OLSR ad hoc networks 

    Medina Medina, Esunly; Meseguer Pallarès, Roc; Molina Clemente, Carlos; Royo Vallés, María Dolores (2010)
    Conference report
    Open Access
    Scalability is a key design challenge that routing protocols for ad hoc networks must properly address to maintain the network performance when the number of nodes increases. We focus on this issue by reducing the amount ...
  • Performance analysis of non-uniform cache architecture policies for chip-multiprocessors using the Parsec v2.0 Benchmark Suite 

    Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (2009-09)
    Conference report
    Restricted access - publisher's policy
    Non-Uniform Cache Architectures (NUCA)have been proposed as a solution to overcome wire delays that will dominate on-chip latencies in Chip Multiprocessor designs in the near future. This novel means of organization divides ...
  • Reducing energy consumption in human-centric wireless sensor networks 

    Meseguer Pallarès, Roc; Molina Clemente, Carlos; Ochoa, Sergio; Santos, Rodrigo (2012)
    Conference report
    Restricted access - publisher's policy
    Energy consumption is a main research issue in wireless sensor networks; and particularly in those where nodes collaborate to reach a goal. This article explores the energy consumption in mobile devices participating ...
  • The Auction: optimizing banks usage in non-uniform cache architectures 

    Lira Rueda, Javier; Molina Clemente, Carlos; González Colás, Antonio María (Association for Computing Machinery (ACM), 2010)
    Conference report
    Restricted access - publisher's policy
    The growing influence of wire delay in cache design has meant that access latencies to last-level cache banks are no longer constant. Non-Uniform Cache Architectures (NUCAs)have been proposed to address this problem. ...
