Application of Multi-core and GPU Architectures on Signal Processing: Case Studies
González, Alberto; BELLOCH, JOSE A.; Piñero, Gema; Lorente, Jorge; Ferrer, Miguel; Roger, Sandra; Roig, Carles; Martínez, Francisco J.; De Diego, María; Alonso-Jordá, Pedro; García, Víctor M.; Quintana-Orti, Enrique S.; Remón Gómez, Alfredo; Vidal, Antonio M. Universidad Politécnica de Valencia (2010)In this article part of the techniques and developments we are carrying out within the INCO2 group are reported. Results follow the interdisciplinary approach with which we tackle signal processing applications. Chosen ... -
Fast block QR update in digital signal processing
Alventosa, Fran J.; Alonso-Jordá, Pedro; Vidal, Antonio M.; Piñero, Gema; Quintana-Orti, Enrique S. Springer (2019-03)The processing of digital sound signals often requires the computation of the QR factorization of a rectangular system matrix. However, sometimes, only a given (and probably small) part of the system matrix varies from the ... -
On the performance of multi-GPU-based expert systems for acoustic localization involving massive microphone arrays
BELLOCH, JOSE A.; González, Alberto; Vidal, Antonio M.; Cobos, Maximo Elsevier (2015)Sound source localization is an important topic in expert systems involving microphone arrays, such as automatic camera steering systems, human–machine interaction, video gaming or audio surveillance. The Steered Response ... -
Solving weighted least squares (WLS) problems on arm-based architectures
BELLOCH, JOSE A.; Bank, Balázs; Igual, Francisco; Quintana-Orti, Enrique S.; Vidal, Antonio M. Springer (2016-11)The Weighted Least Squares algorithm (WLS) is applied to numerous optimization problems, but requires the use of high computational resources, especially when complex arithmetic is involved. This work aims to accelerate ... -
The Impact of the Multi-core Revolution on Signal Processing
González, Alberto; BELLOCH, JOSE A.; Martínez, Francisco J.; Alonso-Jordá, Pedro; García, Víctor M.; Quintana-Orti, Enrique S.; Remón Gómez, Alfredo; Vidal, Antonio M. Universidad Politécnica de Valencia (2010)This paper analyzes the influence of new multi- core and many-core architectures on Signal Processing. The article covers both the architectural design and the programming models of current general-purpose multi-core ...
