    • Elasticity and Petri nets 

      Cortadella, Jordi; Kishinevsky, Michael; Bufistov, Dmitry; Carmona Vargas, Josep; Julvez Bueno, Jorge Emilio (2008-01)
      Article
      Open Access
      Digital electronic systems typically use synchronous clocks and primarily assume fixed duration of their operations to simplify the design process. Time elastic systems can be constructed either by replacing the clock with ...
    • Event-driven optimization-based control of hybrid systems with integral continuous-time dynamics 

      Di Cairano, S.; Bemporad, A; Julvez Bueno, Jorge Emilio (2009-05)
      Article
      Restricted access - publisher's policy
      In this paper we introduce a class of continuous-time hybrid dynamical systems called integral continuous-time hybrid automata (icHA) for which we propose an event-driven optimization-based control strategy. Events include ...
    • On the performance evaluation of multi-guarded marked graphs with single-server semantics 

      Julvez Bueno, Jorge Emilio; Cortadella, Jordi; Kishinevsky, Michael (2010-09)
      Article
      Open Access
      In discrete event systems, a given task can start executing when all the required input data are available. The required input data for a given task may change along the evolution of the system. A way of modeling this ...
    • Performance optimization of elastic systems using buffer resizing and buffer insertion 

      Bufistov, Dmitry; Julvez Bueno, Jorge Emilio; Cortadella, Jordi (Institute of Electrical and Electronics Engineers (IEEE), 2008)
      Conference report
      Open Access
      Buffer resizing and buffer insertion are two transformation techniques for the performance optimization of elastic systems. Different approaches for each technique have already been proposed in the literature. Both techniques ...
    • Performance-preserving clustering of elastic controllers 

      Carmona Vargas, Josep; Julvez Bueno, Jorge Emilio; Cortadella, Jordi; Kishinevsky M. (2008-02-15)
      External research report
      Open Access
      Asynchronous and latency-insensitive circuits offer a similar form of elasticity that tolerates variations in the delays or the latencies of the computation and communication resources of a system. This flexibility comes ...
    • Retiming and recycling for elastic systems with early evaluation 

      Bufistov, Dmitry; Cortadella, Jordi; Galcerán Oms, Marc; Julvez Bueno, Jorge Emilio; Kishinevsky, Mike (2009-04)
      External research report
      Open Access
      Retiming and recycling are two transformations used to optimize the performance of latency-insensitive (a.k.a. synchronous elastic) systems. This paper presents an approach that combines these two transformations for ...
    • Scheduling synchronous elastic designs 

      Carmona Vargas, Josep; Julvez Bueno, Jorge Emilio; Cortadella, Jordi; Kishinevsky, Mike (2009)
      Conference report
      Open Access
      Asynchronous and latency-insensitive circuits offer a similar form of elasticity that tolerates variations in the delays of communication resources of a system. This flexibility comes at the expense of including a control ...
