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 (UML) 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 predecessors, Real Time UML, Third Edition, provides an overview of the essentials of real-time systems and an introduction to UML that focuses on the use of the ever-evolving standard in design and development. This accessible book examines requirements analysis, the definition of object structure and behavior, architectural and mechanistic design, and more detailed designs that encompass data structure, operations, and exceptions. Numerous figures help illustrate UML design techniques, and detailed, real-world examples show the application of those techniques to embedded systems. This significantly revised edition features the new UML 2.0 standard, which dramatically improves the clarity of the UML for capturing architectures and improving its scalability. Real Time UML, Third Edition, also introduces the UML Profile for Schedulability, Performance, and Time (STP Profile). The STP Profile provides a standardized way to capture schedulability and performance constraints of systems. This allows analysis tools to read and analyze UML models.
