A proposed design environment for dependable embedded systems (1997)
Presentation / Conference Contribution

Proposals for an integrated design environment to ease the design of complex embedded systems are presented. Embedded systems are computer-based systems which must respond to external stimuli within time scales determined by the external environment....

Experimental comparison of voting algorithms in cases of disagreement (1997)
Presentation / Conference Contribution

Voting algorithms are used to mask erroneous results from redundant subsystems (variants) in fault tolerant systems. While voting algorithms are well known and widely used, the authors are not aware of any detailed investigation of voter behaviour in...

Testing fault-tolerant systems using a unified error model (1997)
Presentation / Conference Contribution

This paper presents a method of designing test data based around a unified error model. The model allows error 'surfaces' to be defined for a given application, and used to define a test region(s) that give a measure of test coverage. The paper appli...

Error model for computer control systems (1996)
Presentation / Conference Contribution

This paper presents an error model that is intended to allow the dependability of computer control systems, with fault tolerant mechanisms included, to be evaluated. The model allows error `surfaces' to be defined for a given application, and used to... Read More about Error model for computer control systems.

The development framework: Work in progress towards a real-time control system design environment (1996)
Presentation / Conference Contribution

This paper describes work in progress on two extensions to the environment of a Development Framework for the design of control system software; hybrid system design and design of dependable systems. The Development Framework automatically converts a... Read More about The development framework: Work in progress towards a real-time control system design environment.

Intelligent voting strategies for dependable real-time control systems (1995)
Presentation / Conference Contribution

An intelligent and dependable voting mechanism for use in real-time control applications is presented. Strategies proposed by current safety standards advocate N-version software to minimise the effects from undetected software design faults (bugs)....

Dependability modelling in a prototype Development Framework (1995)
Presentation / Conference Contribution

The Development Framework provides a highly automatic translation from a specification to an implementation. The specification is in a popular, graphical control engineering notation typically representing a system with stringent reliability requirem...

Prototype framework of design tools for computer-aided control engineering (1994)
Presentation / Conference Contribution

This paper introduces a framework of tools which allow the design of distributed, potentially fault-tolerant, real-time control software. This framework takes a system specified in the control engineering domain and translates this application-orient...

Voting Software for Fault-Tolerant Aircraft Flight Control Systems (1992)
Presentation / Conference Contribution

An intelligent and robust voting service is proposed. The novel voting service, is capable of forming a consensus based on performance of redundant applications in the value, time and reliability domains. The voter is distributed using a hot backup a...
