  • A content aware integer register file organization 

    González García, Rubén; Cristal Kestelman, Adrián; Ortega Fernández, Daniel; Veidenbaum, Alex; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2004)
    Conference report
    Open Access
    A register file is a critical component of a modern superscalar processor. It has a large number of entries and read/write ports in order to enable high levels of instruction parallelism. As a result, the register file's ...
  • A novel architecture for large windows processors 

    González, Isidro; Galluzzi, Marco; Veidenbaum, Alex; Ramírez, Marco Antonio; Cristal Kestelman, Adrián; Valero Cortés, Mateo (2007-11)
    External research report
    Open Access
    Several processor architectures with large instruction windows have been proposed. They improve performance by maintaining hundreds of instructions in flight to increase the level of instruction parallelism (ILP). Such ...
  • Direct instruction wakeup for out-of-order processors 

    Ramírez, Marco Antonio; Cristal Kestelman, Adrián; Veidenbaum, Alex; Villa, Luis A; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2004)
    Conference report
    Open Access
    Instruction queues consume a significant amount of power in high-performance processors, primarily due to instruction wakeup logic access to the queue structures. The wakeup logic delay is also a critical timing parameter. ...
  • Fast speculative address generation and way caching for reducing L1 data cache energy 

    Nicolaescu, Dan; Salamat, Babak; Veidenbaum, Alex; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2006)
    Conference report
    Open Access
    L1 data caches in high-performance processors continue to grow in set associativity. Higher associativity can significantly increase the cache energy consumption. Cache access latency can be affected as well, leading to ...
  • Power-aware load balancing of large scale MPI applications 

    Etinski, Maja; Corbalán González, Julita; Labarta Mancho, Jesús José; Valero Cortés, Mateo; Veidenbaum, Alex (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Conference report
    Open Access
    Power consumption is a very important issue for HPC community, both at the level of one application or at the level of whole workload. Load imbalance of a MPI application can be exploited to save CPU energy without penalizing ...
