[EN] Numerous signal processing applications are emerging on both mobile and high-performance computing systems. These applications are subject to responsiveness constraints for user interactivity and, at the same time, ...
Fusella, Edoardo; Flich Cardo, José; Cilardo, Alessandro(Institute of Electrical and Electronics Engineers, 2017-05-01)
[EN] Future many-core systems will require energy-efficient, high-throughput and low-latency communication architectures. Silicon Photonics appears today a promising solution towards these goals. The inability of photonics ...
[EN] More than 10 years of research related to the development of efficient GPU routines for the sparse matrix-vector product (SpMV) have led to several realizations, each with its own strengths and weaknesses. In this ...
Martínez Zaldívar, Francisco José; Vidal Maciá, Antonio Manuel; González Salvador, Alberto; Almenar Terré, Vicenç(Springer Verlag (Germany), 2011-12)
[EN] In this paper, we describe a parallel algorithm for LDPC (Low Density Parity Check codes) decoding on a GPU (Graphics Processing Unit) using CUDA (Compute Unified Device Architecture). The strategy of the kernel grid ...
López Espín, José Juan; Vidal Maciá, Antonio Manuel; Giménez ., Domingo(Elsevier, 2012-09)
This paper analyzes the solution of simultaneous equations models. Efficient algorithms for the two-stage least squares method using QR-decomposition are developed and studied. The reduction of the execution time when the ...
