    Accés obert
    In this paper, we address the design of a future high-speed router that supports line rates as high as OC-3072 (160 Gb/s), around one hundred ports and several service classes. Building such a high-speed router would raise ...
  • DLP+TLP processors for the next generation of media workloads 

    Corbal San Adrián, Jesús; Espasa Sans, Roger; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2001)
    Text en actes de congrés
    Accés obert
    Future media workloads will require about two levels of magnitude the performance achieved by current general purpose processors. High uni-threaded performance will be needed to accomplish real-time constraints together ...
