The continuous improvements offered by the silicon technology enables the integration of always increasing number of cores on a single chip. Following this trend, it is expected to approach microprocessor architectures composed of thousands of cores (i.e., kilo-core architectures) in the next future. To cope with the increasing demand for high performance(More)
Evolution of Electronic System Level design meth-odologies, allows a wider use of Transaction-Level Modeling (TLM). TLM is a high-level approach to modeling digital systems that emphasizes on separating communications among modules from the details of functional units. This paper explores different functional testing approaches for the implementation of(More)
—Nowadays, Systems-On-Chip are commonly equipped with reconfigurable hardware. The use of hybrid architectures based on a mixture of general purpose processors and reconfigurable components has gained importance across the scientific community allowing a significant improvement of computational performance. Along with the demand for performance, the great(More)
Large synchronization and communication overhead will become a major concern in future extreme-scale machines (e.g., HPC systems, supercomputers). These systems will push upwards performance limits by adopting chips equipped with one order of magnitude more cores than today. Alternative execution models can be explored in order to exploit the high(More)
Gas chemical sensors are strongly affected by drift, i.e., changes in sensors' response with time, that may turn statistical models commonly used for classification completely useless after a period of time. This paper presents a new classifier that embeds an adaptive stage able to reduce drift effects. The proposed system exploits a state-of-the-art(More)

Future exascale machines will require multi--/ many-core architectures able to efficiently run multi-threaded applications. Data-flow execution models have demonstrated to be capable of improving execution performance by limiting the synchronization overhead. This paper proposes to augment cores with a minimalistic set of hardware units and dedicated(More)
—The trend to develop increasingly more intelligent systems leads directly to a considerable demand for more and more computational power. Programming models that aid to exploit the application parallelism with current multi-core systems exist but with limitations. From this perspective, new execution models are arising to surpass limitations to scale up(More)
