• Boosting Backward Search Throughput for FM-Index Using a Compressed Encoding 

      Herruzo Ruiz, José Manuel; Gonzalez-Navarro, Sonia; Ibáñez, Pablo; Viñals, Victor; Alastruey-Benedé, Jesús; [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, José 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 ...
    • 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 

      Garcia Vega, Carlos (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. ...
