(English) Despite groundbreaking technological innovations, the disparity between processor and memory speeds (known as Memory Wall) is still a major performance obstacle for modern systems. Hardware prefetching is a ...
Pericàs Gleim, Miquel (Date of defense: 2008-12-09)
Diversos motius expliquen l'estancament en el que es troba el desenvolupament del processador tradicional dissenyat per maximitzar el rendiment d'un únic fil d'execució. Per una banda, técniques agressives com la supersegmentacó ...
Salami, Behzad (Date of defense: 2018-11-19)
In this work, we evaluate aggressive undervolting, i.e., voltage underscaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by ...
Moncusí Mercadé, Maria Angels (Date of defense: 2005-12-21)
La evolución de los procesadores siempre ha consistido en ir aumentando el rendimiento de estos, fijando como medida de este aumento de rendimiento la velocidad de proceso en la ejecución de las distintas aplicaciones. Sin ...
Jiménez González, Daniel (Date of defense: 2004-07-02)
En esta tesis analizamos y presentamos algoritmos de ordenación secuencial y paralelo que explotan la jerarquía de memoria del computador usado y/o reducen la comunicación de los datos. Sin embargo, aunque los objetivos ...
