Exploring average-case and probabilistic worst-case performance of time randomised caches and their associated overheads
(Universitat Politècnica de Catalunya, 2016-01)
Master thesis
Open AccessIn this work we focus on the analysis of performance in the context of Probabilistic Timing Analysis (PTA) from different angles. First, we model and evaluate average performance of time-randomised caches used in the context ... -
Increasing the Reliability of Software Timing Analysis for Cache-Based Processors
(IEEE, 2019-06-01)
Article
Open AccessReal-time systems are witnessing a significant increase in critical software's size, complexity, and performance needs, which can only be satisfied with high-performance hardware features. Cache memories, pervasively used ... -
Measurement-based cache representativeness on multipath programs
(Association for Computing Machinery (ACM), 2018-06)
Conference lecture
Open AccessAutonomous vehicles in embedded real-time systems increase critical-software size and complexity whose performance needs are covered with high-performance hardware features like caches, which however hampers obtaining WCET ... -
Modelling probabilistic cache representativeness in the presence of arbitrary access patterns
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Open AccessMeasurement-Based Probabilistic Timing Analysis (MBPTA) is a promising powerful industry-friendly method to derive worst-case execution time (WCET) estimates as needed for critical real-time embedded systems. MBPTA performs ... -
On the assessment of probabilistic WCET estimates reliability for arbitrary programs
(2017-04-11)
Article
Open AccessMeasurement-Based Probabilistic Timing Analysis (MBPTA) has been shown to be an industrially viable method to estimate the Worst-Case Execution Time (WCET) of real-time programs running on processors including several ... -
On the limits of probabilistic timing analysis
(Universitat Politècnica de Catalunya, 2019-12-18)
Doctoral thesis
Open AccessOver the last years, we are witnessing the steady and rapid growth of Critica! Real-Time Embedded Systems (CRTES) industries, such as automotive and aerospace. Many of the increasingly-complex CRTES' functionalities that ... -
On uses of extreme value theory fit for industrial-quality WCET analysis
(IEEE, 2017-07-31)
Conference lecture
Open AccessOver the last few years, considerable interest has arisen in measurement-based probabilistic timing analysis. The term MBPTA has been used to indistinctly refer to a variety of different applications of Extreme Value Theory ... -
Software Time Reliability in the Presence of Cache Memories
(Springer International Publishing, 2017-05-30)
Conference lecture
Open AccessThe use of caches challenges measurement-based timing analysis (MBTA) in critical embedded systems. In the presence of caches, the worst-case timing behavior of a system heavily depends on how code and data are laid out ... -
Validating the reliability of WCET estimates with MBPTA
(Barcelona Supercomputing Center, 2015-05-05)
Conference report
Open AccessEstimating the worst-case execution time (WCET) of tasks in a system is an important step in timing verification of critical real-time embedded systems. Measurement-Based Probabilistic Timing Analysis (MBPTA) is a novel ...
