    • Control speculation for energy-efficient next-generation superscalar processors 

      Aragón, Juan Luis; González González, José; González Colás, Antonio María (2006-03)
      Article
      Open Access
      Conventional front-end designs attempt to maximize the number of "in-flight" instructions in the pipeline. However, branch mispredictions cause the processor to fetch useless instructions that are eventually squashed, ...

    • DTM-NUCA: dynamic texture mapping-NUCA for energy-efficient graphics rendering 

      Corbalán Navarro, David; Aragón, Juan Luis; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference report
      Open Access
      Modern mobile GPUs integrate an increasing number of shader cores to speedup the execution of graphics workloads. Each core integrates a private Texture Cache to apply texturing effects on objects, which is backed-up by a ...

    • Improving the energy efficiency of the graphics pipeline by reducing overshading 

      Corbalán Navarro, David; Aragón, Juan Luis; Anglada Sánchez, Martí; de Lucas Casamayor, Enrique; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (2021)
      Conference report
      Open Access
      The most common task of GPUs is to render images in real time. When rendering a 3D scene, a key step is determining which parts of every object are visible in the final image. There are different approaches to solve the ...

    • Power-aware control speculation through selective throttling 

      Aragón, Juan Luis; González González, José; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2003)
      Conference report
      Open Access
      With the constant advances in technology that lead to the increasing of the transistor count and processor frequency, power dissipation is becoming one of the major issues in high-performance processors. These processors ...

    • Rendering elimination: early discard of redundant tiles in the graphics pipeline 

      Anglada Sánchez, Martí; de Lucas Casamayor, Enrique; Parcerisa Bundó, Joan Manuel; Aragón, Juan Luis; Marcuello Pascual, Pedro; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Restricted access - publisher's policy
      GPUs are one of the most energy-consuming components for real-time rendering applications, since a large number of fragment shading computations and memory accesses are involved. Main memory bandwidth is especially taxing ...

    • Selective branch prediction reversal by correlating with data values and control flow 

      Aragón, Juan Luis; González, José; García Carrasco, José M.; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2001)
      Conference report
      Open Access
      Branch prediction is one of the main hurdles in the roadmap towards deeper pipelines and higher clock frequencies. This work presents a new approach to enhancing current branch predictors: Selective Branch Prediction ...

    • TCOR: a tile cache with optimal replacement 

      Joseph, Diya; Aragón, Juan Luis; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2022)
      Conference report
      Open Access
      Cache Replacement Policies are known to have an important impact on hit rates. The OPT replacement policy [27] has been formally proven as optimal for minimizing misses. Due to its need to look far ahead for future memory ...
