Bandwidth of crossbar and multiple-bus connections for multiprocessors
Lang, Tomás; Valero Cortés, Mateo; Alegre de Miguel, Ignasi (1982-12)
Article
Accés obertIn 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)
Text en actes de congrés
Accés obertThe 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 ... -
Exploiting the locality of memory references to reduce the address bus energy
Musoll Cinca, Enric; Lang, Tomás; Cortadella, Jordi (Association for Computing Machinery (ACM), 1997)
Text en actes de congrés
Accés obertThe energy consumption at the I/O pins is a significant part of the overall chip consumption. This paper presents a method for encoding an external address bus which lowers its activity and, thus, decreases the energy. ... -
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)
Text en actes de congrés
Accés obertThe 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
Accés obertEnergy 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
Accés obertThe 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
Accés obertThe 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
Accés obertThe 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, ...
