Nowadays, by increasing the number of connected devices to Internet rapidly, cloud computing cannot handle the real-time processing. Therefore, fog computing was emerged for providing data processing, filtering, aggregating, ...
There are new mechanisms to sequence and process the genomic code, discovering thus diagnostic tools and treatments. The file for a sequenced genome can reach hundreds of gigabytes. Thus, for further studies, we need new ...
The ever increasing demand for wireless data services has given a starring role to dense small cell (SC) deployments for mobile networks, as increasing frequency re-use by reducing cell size has historically been the most ...
In recent years parallel computing has become ubiquitous. Lead by the spread of commodity multicore processors, parallel programming is not anymore an obscure discipline only mastered by a few.<br/>Unfortunately, the amount ...
Distributed Computing is the paradigm where the application execution is distributed across different computers connected by a communication network. Distributed Computing platforms have evolved very fast during the las ...
SIMD instruction sets are a key feature in current general purpose and high performance architectures. SIMD instructions apply in parallel the same operation to a group of data, commonly known as vector. A single SIMD/vector ...
Since the early 2000s, computer systems have seen a transition from single-core to multi-core systems. While single-core systems included only one processor core on a chip, current multi-core processors include up to tens ...
(Català) A mesura que augmenta el nombre de transistors integrables en un xip, problemes com el desfasament del senyal de rellotge esdevenen cada cop més crítics. Altres avantatges com un consum més baix, una velocitat ...
(English) Sensor Networks (SN) will play an integral role in Beyond 5G (B5G) ecosystems, especially for highly-distributed use cases and services such as Digital Twins (DT). Thus, the underlying transport network needs to ...
Future Critical Real-Time Embedded Systems (CRTES), like those is planes, cars or trains, require more and more guaranteed performance in order to satisfy the increasing performance demands of advanced complex software ...
Las memorias caché fueron incorporadas en los microprocesadores ya desde los primeros tiempos, y representan la solución más común para tratar la diferencia de velocidad entre el procesador y la memoria. Sin embargo, muchos ...
The sustained drive to downsize the transistors has reached a point where device sensitivity against transient faults due to neutron and alpha particle strikes a.k.a soft errors has moved to the forefront of concerns for ...
Despite the fact that the most viable L1 memories in processors are caches, on-chip local memories have been a great topic of consideration lately. Local memories are an interesting design option due to their many benefits: ...
(English) Machine Learning (ML) systems allow the efficient implementation of functionalities that can be hard to program by traditional software due to the high spectrum of inputs that hinder the definition of a specific ...
The worldwide utilization of mobile devices makes the segment of low power mobile processors leading in the entire computer industry. Customers demand low-cost, high-performance and energy-efficient mobile devices, which ...
This work is motivated by the growing intricacy of high performance computing infrastructures. For example, supercomputer MareNostrum (installed in 2005 at BSC) has 10240 processors and currently there are machines with ...
En esta tesis se estudia el modelo de ejecución de los procesadores multithreaded especulativos así como los requisitos necesarios para su implementación. El modelo de ejecución se basa en la inserción de instrucciones de ...
Traditional vector architectures have been shown to be very effective in executing regular codes in which the compiler can detect data-level parallelism, i.e. repeating the same computation over different elements in the ...
This thesis presents novel methods based on a combination of well-known statistical techniques for faster estimation of memory yield and their application in the design of energy-efficient subthreshold memories. The emergence ...
Uno de los problemas más complejos en redes de computadores es el de proporcionar garantías de calidad y confiabilidad a las comunicaciones de datos entre entidades que se encuentran en dominios distintos. Esto se debe a ...
