  • Boosting Guaranteed Performance in Wormhole NoCs with Probabilistic Timing Analysis 

    Slijepcevic, Mladen; Hernandez, Carles; Abella, Jaume; Cazorla, Francisco J. (IEEE, 2017-09-28)
    Conference lecture
    Open Access
    Wormhole-based NoCs (wNoCs) are widely accepted in high-performance domains as the most appropriate solution to interconnect an increasing number of cores in the chip. However, wNoCs suitability in the context of critical ...
  • Design and implementation of a fair credit-based bandwidth sharing scheme for buses 

    Slijepcevic, Mladen; Hernandez, Carles; Abella, Jaume; Cazorla, Francisco J. (Institute of Electrical and Electronics Engineers (IEEE), 2017-05-15)
    Conference lecture
    Open Access
    Fair arbitration in the access to hardware shared resources is fundamental to obtain low worst-case execution time (WCET) estimates in the context of critical real-time systems, for which performance guarantees are essential. ...
  • DTM: degraded test mode for fault-aware probabilistic timing analysis 

    Slijepcevic, Mladen; Kosmidis, Leonidas; Abella Ferrer, Jaume; Quiñones, Eduardo; Cazorla Almeida, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2013)
    Conference report
    Restricted access - publisher's policy
    Existing timing analysis techniques to derive Worst-Case Execution Time (WCET) estimates assume that hardware in the target platform (e.g., the CPU) is fault-free. Given the performance requirements increase in current ...

    Conference lecture
    Open Access
    The use of increasingly complex hardware and software platforms in response to the ever rising performance demands of modern real-time systems complicates the verification and validation of their timing behaviour, which ...
  • pTNoC: Probabilistically time-analyzable tree-based NoC for mixed-criticality systems 

    Slijepcevic, Mladen; Fernández, Mikel; Hernández, Carles; Abella, Jaume; Quiñones, Eduardo; Cazorla Almeida, Francisco Javier (Institute of Electrical and Electronics Engineers (IEEE), 2016)
    Conference report
    Open Access
    The use of networks-on-chip (NoC) in real-time safety-critical multicore systems challenges deriving tight worst-case execution time (WCET) estimates. This is due to the complexities in tightly upper-bounding the contention ...
  • Time-analysable non-partitioned shared caches for real-time multicore systems 

    Slijepcevic, Mladen; Kosmidis, Leonidas; Abella Ferrer, Jaume; Quiñones, Eduardo; Cazorla Almeida, Francisco Javier (Association for Computing Machinery (ACM), 2014)
    Conference report
    Restricted access - publisher's policy
    Shared caches in multicores challenge Worst-Case Execution Time (WCET) estimation due to inter-task interferences. Hard-ware and software cache partitioning address this issue although they complicate data sharing among ...
