Real-Time Embedded Systems: Design Principles and Engineering Practices

This book integrates new ideas and topics from real time systems, embedded systems, and software engineering to give a complete picture of the whole process of developing software for real-time embedded applications. You will not only gain a thorough understanding of concepts related to microprocessors, interrupts, and system boot process, appreciating the importance of real-time modeling and scheduling, but you will also learn software engineering practices such as model documentation, model analysis, design patterns, and standard conformance. . This book is split into four parts to help you learn the key concept of embedded systems; Part one introduces the development process, and includes two chapters on microprocessors and interrupts---fundamental topics for software engineers; Part two is dedicated to modeling techniques for real-time systems; Part three looks at the design of software architectures and Part four covers software implementations, with a focus on POSIX-compliant operating systems. With this book you will learn:. . The pros and cons of different architectures for embedded systems . POSIX real-time extensions, and how to develop POSIX-compliant real time applications . How to use real-time UML to document system designs with timing constraints. The challenges and concepts related to cross-development . Multitasking design and inter-task communication techniques (shared memory objects, message queues, pipes, signals). How to use kernel objects (e.g. Semaphores, Mutex, Condition variables) to address resource sharing issues in RTOS applications . The philosophy underpinning the notion of "resource manager" and how to implement a virtual file system using a resource manager . The key principles of real-time scheduling and several key algorithms
