Near-optimal Deployment of Dataflow Applications on Many-core Platforms with Real-time Guarantees

Safe and optimal deployment of data-streaming applications on many-core platforms requires the realistic estimation of task Worst-Case Execution Time (WCET). On the other hand, task WCET depends on the deployment solution, due to the varying number of inte ...

Safe and Efficient Deployment of Data-Parallelisable Applications on Many-Core Platforms: Theory and Practice

Giovanni De Micheli, Federico Angiolini, Alena Simalatsar, Stefanos Skalistis

The safe and, at the same time, efficient deployment of parallelisable applications on many-core platforms is a challenging task. Theoretical Models of Computation (MoC) require the realistic estimation of task Worst-Case Execution Time (WCET ...

Efficient Adaptive Hard Real-time Multi-processor Systems

Stefanos Skalistis

Modern computing systems are based on multi-processor systems, i.e. multiple cores on the same chip. Hard real-time systems are required to perform particular tasks within certain amount of time; failure to do so characterises an unaccepted behavior. Hard ...

Assessment of Image Quality vs. Computation Cost for Different Parameterizations of Ultrasound Imaging Pipelines

Jean-Philippe Thiran, Giovanni De Micheli, Federico Angiolini, Marcel Arditi, Alena Simalatsar, Stefanos Skalistis, Aya Mohamed Naguib Ahmed Ibrahim

Ultrasound imaging is a technique widely used in medicine to visualize organs and other body structures, capturing their position, size, morphology and any pathological lesions. Its use is unfortunately limited to specialized centers with trained personnel ...

Modeling of Reconfigurable Medical Ultrasonic Applications in BIP

Alena Simalatsar, Stefanos Skalistis

Medical ultrasonic imaging applications require high quality of images produced in real-time often with limited resources available. Deadlock-freedom and confluency must be guaranteed to ensure the correctness of the applications, while feasibility and opt ...
