Boosting Backward Search Throughput for FM-Index Using a Compressed Encoding
Herruzo-Ruiz, Jose Manuel
; Gonzalez-Navarro, Sonia; Ibáñez, Pablo; Viñals, Victor; Alastruey-Benedé, Jesús; Plata-Gonzalez, Oscar Guillermo[et al.] (2019-04-11)
The rapid development of DNA sequencing technologies has demanded for com- pressed data structures supporting fast pattern matching queries. FM-index is a widely-used compressed data structure that also supports fast ... -
Fast HUB Floating-point Adder for FPGA
Villalba-Moreno, Julio; Hormigo-Aguilar, Javier; Gonzalez-Navarro, Sonia (2018-10-17)
Several previous publications have shown the area and delay reduction when implementing real number computation using HUB formats for both floating-point and fixed-point. In this paper, we present a HUB floating-point ... -
Genome sequence alignment in processing-In-memory architectures
Herruzo-Ruiz, Jose Manuel (UMA Editorial, 2021-01-27)
La combinación de la aparición de un cuello de botella en el acceso a los datos y la creciente importancia de las aplicaciones de procesamiento intensivo de datos, muy limitadas por el sistema de memoria, crea un importante ... -
New Results on Non-normalized Floating-point Formats
Gonzalez-Navarro, Sonia; Hormigo-Aguilar, Javier (IEEE Computer Society, 2019)
Compulsory normalization of the represented numbers is a key requirement of the floating-point standard. This requirement contributes to fundamental characteristics of the standard, such as taking the most of the precision ... -
Normalizing or not normalizing? An open question for floating-point arithmetic in embedded systems
Gonzalez-Navarro, Sonia; Hormigo-Aguilar, Javier (IEEE, 2017-07-24)
Emerging embedded applications lack of a specific standard when they require floating-point arithmetic. In this situation they use the IEEE-754 standard or ad hoc variations of it. However, this standard was not designed ... -
TraTSA: A Transprecision Framework for Efficient Time Series Analysis
Fernández-Vega, Iván; Quislant-del-Barrio, Ricardo; Gonzalez-Navarro, Sonia; Gutierrez-Carrasco, Eladio Damian; Plata-Gonzalez, Oscar Guillermo (Elsevier, 2022-09)
Time series analysis (TSA) comprises methods for extracting information in domains as diverse as medicine, seismology, speech recognition and economics. Matrix Profile (MP) is the state-of-the-art TSA technique, which ... -
Unbiased Rounding for HUB Floating-point Addition
Villalba-Moreno, Julio; Hormigo-Aguilar, Javier; Gonzalez-Navarro, Sonia (2018-06-28)
Half-Unit-Biased (HUB) is an emerging format based on shifting the represented numbers by half Unit in the Last Place. This format simplifies two’s complement and roundto- nearest operations by preventing any carry ... -
Variable radix online decimal arithmetic
(UMA Editorial, 2017-06-30)En esta tesis se estudia la unión de la aritmética decimal y la artimética online para obtener un sistema online para operar con dígitos decimales usando la codificación RBCD que cumple con los requisitos de ambas aritméticas. ...
