Real-Time UML: Developing Efficient Objects for Embedded Systems (Addison-wesley Object Technology Series)

The increasing complexity of embedded and real-time systems requires a more premeditated and sophisticated design approach for successful implementation. The object-based Unified Modeling Language (UMQ can describe the structural and behavioral aspects critical to real-time systems, and has come to the fore as an outstanding medium for effective design. Like its best-selling predecessor, Real-Time UML, Second Edition, provides an overview of the essentials of real-time systems and an introduction to UML that focuses on its use in design and development. The book examines requirements analysis, the definition of object structure and object behavior, architectural design, mechanistic design, and more detailed designs that encompass data structure, operations, and exceptions. Numerous figures help illustrate UML design techniques, and detailed, realworld examples show the application of those techniques to embedded systems. This edition features version 1.3 of the UML standard and includes extensive coverage of the action semantics metamodel and statecharts, as well as further descriptions and demonstrations of how to effectively apply use cases and capture object models and state behavior. Real-Time UML, Second Edition, also introduces an elaboration on the author's proven product development process, Rapid Object-Oriented Process for Embedded Systems (ROPES), and a new appendix on the UML extension process. Key topic coverage includes: • Specifying external events • Identifying use cases • Response time • Concurrent collaboration diagrams • Key strategies for object identification • Defining object state behavior • UML state diagrams • Orthogonal components and concurrency • Implementing state machines • Representing physical architecture in UML • Safety and reliability patterns • Concurrent state diagrams • Assigning priorities • State behavior patterns
