      Power density has become the limiting factor in technology scaling as power budget restricts the amount of hardware that can be active at the same time. Reducing supply voltage to ultra-low voltage ranges close to the ...
    • Compression-aware and performance-efficient insertion policies for long-lasting hybrid LLCs 

      Escuín Blasco, Carlos; Ali Khan, Asif; Ibáñez, Pablo Enrique; Monreal Arnal, Teresa; Castrillón, Jerónimo; Viñals Yúfera, Victor (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Conference report
      Open Access
      Emerging non-volatile memory (NVM) technologies can potentially replace large SRAM memories such as the last-level cache (LLC). However, despite recent advances, NVMs suffer from higher write latency and limited write ...
    • Concertina: Squeezing in cache content to operate at near-threshold voltage 

      Ferrerón, Alexandra; Suárez Gracia, Darío; Alastruey, Jesús; Monreal Arnal, Teresa; Ibáñez, Pablo (2016-03-01)
      Article
      Open Access
      Scaling supply voltage to values near the threshold voltage allows a dramatic decrease in the power consumption of processors; however, the lower the voltage, the higher the sensitivity to process variation, and, hence, ...
    • Delaying physical register allocation trought virtual-physical registers 

      Monreal Arnal, Teresa; González Colás, Antonio María; Valero Cortés, Mateo; González González, José; Viñals Yufera, Víctor (Institute of Electrical and Electronics Engineers (IEEE), 1999)
      Conference report
      Open Access
      Register file access time represents one of the critical delays of current microprocessors, and it is expected to become more critical as future processors increase the instruction window size and the issue width. This ...
