Modelling and Verifying an Evolving Distributed Control System Using an Event-Based Approach [chapter]

Christian Attiogbé
2014 Lecture Notes in Computer Science  
The components of the systems are software components or physical components but their abstract models are considered with the aim of modelling and reasoning.  ...  The proposed approach is first presented, then the CCTV case study is introduced and modelled. The resulting model is structured as a B abstract machine.  ...  The reconfiguration of the system architecture for example does not impact on the modelling and the control of the system.  ...

Resource estimation methodology for multimedia applications

Hari Kalva, Ravi Shankar, Tuhina Patel, Camilo Cruz, Roger Zimmermann, Carsten Griwodz
2007 Multimedia Computing and Networking 2007  
The resources required to decode H.264 video are estimated based on a measure of the complexity of the H.264 bitstreams and the target architecture.  ...  These resource estimates and video bitstream complexity are used in developing a parametric model for resource estimation based on bitstream complexity.  ...  A resource estimation model that combines Bitstream Abstraction, Decoder Abstraction, and target architecture dependencies can be used to quickly determine resource requirements.  ...

2004 Software engineering notes  
However, the behaviour models required are those for the full generality of the system architecture, and not the simplified architecture used for scenarios.  ...  Constructing rigorous models for analysing the behaviour of concurrent and distributed systems is a complex task. Our aim is to facilitate model construction.  ...  ACKNOWLEDGMENTS The authors acknowledge that this research was supported in part by the STATUS ESPIRIT project (IST-2001-32298) and EPSRC grant READS GR/S03270/01.  ...

Model-based Decoder Specifications for the Long-Term Preservation of Video Content

Christian Schenk
2016 International Conference on Software Technologies: Applications and Foundations  
This way, it is ensured that most commonly used formats can also be decoded on future architectures.  ...  Common video formats are quite complex, and the conversion of digital video content without risking any loss of authenticity or information is usually not possible.  ...  Efficiency mostly is accompanied by system-dependence, and that is why modern serialization formats are commonly tailored to current architectures.  ...
