The increasing demand for new functionalities in current and future hard real-time embedded systems, like the ones deployed in automotive and avionics industries, is driving an increment in the performance required in ...
Increasingly High-Performance Computing (HPC) applications run on heterogeneous multi-core platforms. The basic reason of the growing popularity of these architectures is their low power consumption, and high throughput ...
Internet security poses complex challenges at different levels, where even the basic requirement of availability of Internet connectivity becomes a conundrum sometimes. Recent Internet service disruption events have made ...
En los últimos años, las nuevas aplicaciones de Internet tales como aplicaciones multimedia, video a demanda, etc, requieren progresivamente mayor capacidad y garantías de calidad de servicio. En ese sentido el modelo de ...
Vehicular Ad-Hoc NETworks (VANETs) are an emerging technology which aims to improve road safety by preventing and reducing traffic accidents. While VANETs offer a great variety of promising applications, such as, safety-related ...
(English) In this thesis, we study the challenges preventing ASR deployment on edge devices and propose innovations to tackle them, hopefully moving the technology a step forward to the future. First, we characterize ...
Today there are two main vector processors design trends. On the one hand, we have vector processors designed for long vectors lengths such as the SX-Aurora TSUBASA which implements vector lengths of 256 elements (16384-bits). ...
(English) Deep Neural Networks (DNNs) have become ubiquitous in a wide range of application domains. Despite their success, training DNNs is an expensive task which has motivated the use of reduced numerical precision ...
El creixement experimentat tant per la web com per Internet en els últims anys ha potenciat l'introducció de servidors d'aplicacions dins de la majoria d'entorns d'execució distribuits. El servidors d'aplicacions web porten ...
Technology in the twenty-first century is rapidly developing and driving us into a new smart computing world, and emerging lots of new computing architectures. Fog-to-Cloud (F2C) is among one of them, which emerges to ...
Les últimes dècades el rendiment dels processadors i de les memòries ha millorat a diferent ritme, limitant el rendiment dels processadors i creant el conegut memory gap. Sol·lucionar aquesta diferència de rendiment és un ...
Uno de los mayores retos que debe ser afrontado por los diseñadores de micro-procesadores es el de mitigar la gran latencia de las instrucciones de carga de datos en registros. Esta tesis analiza una de las posibles ...
Network monitoring has always been a topic of foremost importance for both network operators and researchers for multiple reasons ranging from anomaly detection to tra c classi cation or capacity planning. Nowadays, as ...
Today, vast streams of structured and unstructured data have been incorporated in databases, and analytical processes are applied to discover patterns, correlations, trends and other useful relationships that help to take ...
(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 ...
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 ...
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 ...
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 ...
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 ...
During many years, people and governments have been warned about the increasing levels of pollution and greenhouse gases (GHG) emissions that are endangering our lives on this planet. The Information and Communication ...
