Recently, high performance processor designs have evolved toward Chip-Multiprocessor (CMP) architectures to deal with instruction level parallelism limitations and, more important, to manage the power consumption that is ...
Amaral, Marcelo (Date of defense: 2019-04-29)
In recent years there has been an extraordinary growth of the Internet of Things (IoT) and its protocols. The increasing diffusion of electronic devices with identification, computing and communication capabilities is ...
Radojković, Petar (Date of defense: 2013-07-19)
This thesis presents cross-domain approaches that improve the effective use of multithreaded architectures. The contributions of the thesis can be classified in three groups. First, we propose several methods for thread ...
Jiménez Pérez, Víctor Javier (Date of defense: 2016-10-20)
Increasing processors' clock frequency has traditionally been one of the largest drivers of performance improvements for computing systems. In the first half of the 2000s, however, it became clear that continuing to increase ...
Karakostas, Vasileios (Date of defense: 2016-04-18)
Virtual memory improves programmer productivity, enhances process security, and increases memory utilization. However, virtual memory requires an address translation from the virtual to the physical address space on every ...
Jalle Ibarra, Javier (Date of defense: 2016-07-18)
Critical Real-Time Embedded Systems (CRTES) follow a verification and validation process on the timing and functional correctness. This process includes the timing analysis that provides Worst-Case Execution Time (WCET) ...
