  • Bandwidth of crossbar and multiple-bus connections for multiprocessors 

    Lang, Tomás; Valero Cortés, Mateo; Alegre de Miguel, Ignasi (1982-12)
    Article
    Open Access
    In this paper we compare the effective bandwidth in a multiprocessor with shared memory using as interconnection networks the crossbar or the multiple-bus. We consider a system with N processors and N memory modules, in ...
  • Division with speculation of quotient digits 

    Cortadella, Jordi; Lang, Tomás (Institute of Electrical and Electronics Engineers (IEEE), 1993)
    Conference report
    Open Access
    The speed of SRT-type dividers is mainly determined by the complexity of the quotient-digit selection, so that implementations are limited to low-radix stages. A scheme is presented in which the quotient-digit is speculated ...
  • Extension of the working-zone-encoding method to reduce the energy on the microprocessor data bus 

    Lang, Tomás; Musoll Cinca, Enric; Cortadella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 1998)
    Conference report
    Open Access
    The energy at the I/O pins is a significant part of the overall consumption of a chip. To reduce this energy, this work extends to the data bus the working zone encoding method originally applied to encoding an external ...
  • Individual flip-flops with gated clocks for low power datapaths 

    Lang, Tomás; Cortadella, Jordi; Musoll Cinca, Enric (Institute of Electrical and Electronics Engineers (IEEE), 1997-06)
    Article
    Open Access
    Energy consumption has become one of the important factors in digital systems, because of the requirement to dissipate this energy in high-density circuits and to extend the battery life in portable systems such as devices ...
  • Reduction of connections for multibus organization 

    Lang, Tomás; Valero Cortés, Mateo; Fiol Mora, Miquel Àngel (1983-08)
    Article
    Open Access
    The multibus interconnection network is an attractive solution for connecting processors and memory modules in a multiprocessor with shared memory. It provides a throughput which is intermediate between the single bus and ...
  • Synchronized access to streams in multiprocessors 

    Peiron Guàrdia, Montse; Valero Cortés, Mateo; Ayguadé Parra, Eduard; Lang, Tomás (Institute of Electrical and Electronics Engineers (IEEE), 1993-10)
    Article
    Open Access
    The synchronized and simultaneous access to several vectors that form a single stream occurs in SIMD vector multiprocessors as well as in MIMD superscalar multiprocessors with decoupled access. In this paper we propose a ...
  • Working-zone encoding for reducing the energy in microprocessor address buses 

    Musoll Cinca, Enric; Lang, Tomás; Cortadella, Jordi (1998-12)
    Article
    Open Access
    The energy consumption due to input-output pins is a substantial part of the overall chip consumption. To reduce this energy, this work presents the working-zone encoding (WZE) method for encoding an external address bus, ...
