This book covers the basic concepts and principles of operating systems, showing how to apply them to the design and implementation of complete operating systems for embedded and real-time systems. It includes all the foundational and background information on ARM architecture, ARM instructions and programming, toolchain for developing programs, virtual machines for software implementation and testing, program execution image, function call conventions, run-time stack usage and link C programs with assembly code. Embedded and Real-Time Operating Systems describes the design and implementation of a complete OS for embedded systems in incremental steps, explaining the design principles and implementation techniques. For Symmetric Multiprocessing (SMP) embedded systems, the author examines the ARM MPcore processors, which include the SCU and GIC for interrupts routing and interprocessor communication and synchronization by Software Generated Interrupts (SGIs).

This Second Edition covers ARM64 architecture and programming. These include exception levels, vector tables and exceptions handling, GICv3 programming and interrupt processing. It covers virtual to physical address mappings in ARMv8, and shows a 64-bit OS with kernel space in EL1 and separate user spaces in EL0. It also covers ARM TrustZone technology and secure systems. These include hardware and software architectures for secure and normal worlds, interactions and switching between the two worlds. It shows a secure world comprising a secure monitor in EL3 to provide service functions, and a normal world comprising processes in non-secure EL1, which use SMC to access service functions in the secure world. Throughout the book, complete working sample systems demonstrate the design principles and implementation techniques.

The objective of this book is to provide a suitable platform for teaching and learning the theory and practice of embedded and real-time operating systems. It covers embedded systems architecture, embedded systems programming, basic concepts and principles of operating systems (OS), and real-time systems. It shows how to apply these principles and programming techniques to the design and implementation of real OS for both embedded and real-time systems. This book is intended for computer science students and computer professionals, who wish to study the internal details of embedded and real-time operating systems. It is suitable as a textbook for courses on embedded and real-time systems in technically oriented computer science/engineering curricula that strive for a balance between theory and practice. The book’s evolutional style, coupled with detailed example code and complete working sample systems, makes it especially suitable for self-study by computer enthusiasts.

The book covers the entire spectrum of software design for embedded and real-time systems, ranging from simple super-loop and event-driven control programs for uniprocessor (UP) systems to complete symmetric multiprocessing (SMP) operating systems on multicore systems. It is also suitable for advanced study of embedded and real-time operating systems.
