Applying Real-Time UML

Analysing and Formalising System Requirements:

• Scenarios and use cases
• System scope and direct and indirect actors.
• Modelling actor-system interactions graphically

Defining System and Software Requirements:

• The system use case model
• The system interaction model
• The system scope model
• The system dynamic model
• The software use case model

Developing Larger Systems:

• Developing the subsystem model
• Packages and components
• Interfacing to the real-world; device-software interactions

Developing the Ideal Object model:

• Object relationships, communication and control in an ideal environment

Developing the Specification Model:

• Mismatches between the ideal and the implementation models
• Composite structures, ports and provided/required interfaces

Concurrent Systems and Task-based Design:

• Problems with abstract software design
• Fundamentals of multitasking design

Implementation Modelling - The Tasking Model:

• Mapping the specification model to the implementation one
• Issues of inter-task communication

Implementation Modelling - The Practical Sequential Model:

• Controlling the collective behaviour of objects in sequential code: the coordinator object
• Specifying algorithmic (processing) operations using activity diagrams

Code-related Issues:

• Logical and physical models
• Software - constructs and artefacts
• Structuring and packaging of software
• Implementation modelling.

Distributed and Multi-computer Systems:

• Multi-computer architectures for real-time systems
• Criteria for mapping software onto hardware
• A practical design technique

Case Study:

• The case study, which is an integral part of the course, is based on developing software for an embedded application.
