There exist algorithms, also called "fast" algorithms, which exploit the special structure of Toeplitz matrices so that, e.g., allow to solve a linear system of equations in O(n2) flops. However, some implementations of ...

[EN] The input and output signals of a digital signal processing system can often be represented by a rectangular matrix as it is the case of the beamformer algorithm, a very useful particular algorithm that allows extraction ...

Tablets and smart phones are nowadays equipped with low-power processor architectures such as the ARMv7 and the ARMv8 series. These processors integrate powerful SIMD units to exploit the intrinsic data-parallelism of ...

[EN] In this work we introduce new rational-polynomial Hermite matrix expansions which allow us to obtain a new accurate and efficient method for computing the matrix cosine. This method is compared with other state-of-the-art ...

[ES] El trabajo realizado en este TFM ha consistido en realizar una aplicación que mediante el análisis de datos de los datos recopilados mediante la plataforma API APP CIUDAD obtenga unos resultados y los proporcione ...

Large-scale distributed systems (e.g., datacenters, HPC systems, clouds, large-scale networks, etc.) con- sume and will consume enormous amounts of energy. Therefore, accurately monitoring the power dissipation and energy ...

Auto-tuning techniques have been used in the design of routines in recent years. The goal is to develop routines which automatically adapt to the conditions of the computational system in such a way that efficient executions ...

[ES] El software de visión/expulsión MVS de la empresa MultiScan Technologies controla el funcionamiento de las máquinas que produce esta compañía. Este software ha sido desarrollado y mejorado con el paso de los años por ...

[EN] This paper presents an implementation of one of the most up-to-day algorithms proposed to compute the matrix trigonometric functions sine and cosine. The method used is based on Taylor series approximations which ...
