Embedded Operating Systems

Introduction
Basic services of operating systems, using operating systems in embedded environment. Operating system selection guidelines.

Simple operating systems
The architecture and services of the uCOS-II and the FreeRTOS operating systems. Scheduling algorithm, task registry, supported services, intertask communication.

GNU/Linux operating system
The history and the general features of GNU/Linux operating system. The main components of the Kernel related to real-time operation: scheduling, memory management, interrupt handling. The structure of the Linux operating systems. Most commonly used Unix commands, and the BASH shell command interpreter and programming. Security and authorization is Linux, simple regular expressions, process management.

Embedded Linux
The structure and the components of a minimal x86 based Linux system in details. Common configuration services.
Cross-platform Linux system generation for ARM devices. Automatic embedded Linux system generation tools: Buildroot, OpenEmbedded, Yocto Project. The structure and the usage of the  Yocto Project.

Application development for Linux platform
Getting familiar with the development tools: compiler toolchain(gcc), libraries, Makefile, debug tools (gdb, malloc debugs, valgrind, strace), integrated development environments
File abstraction, file handling system calls, i-node handling functions. Concurrent programming: processes, interprocess communication, synchronization. I/O multiplexing and the ioctl system call. Developing real-time applications. Network communication using the Berkley socket API.

Development of Linux kernel modules
The basics of the kernel development. Using, writing and compiling kernel modules. Parameter passing to kernel modules. Structure of a character based device driver. Device driver registration procedure. Handling concurrency in the kernel: atomic operations, spinlock, semaphore, mutex, reader/writer constructions. I/O port and interrupt handling in practice.

Embedded Windows operating systems
Windows in the world of embedded systems. The architecture and the services of Windows Embedded and the Windows Embedded Compact. Scheduling, synchronization objects, interrupt handling. BSP implementation, driver models. Native WinAPI application development.

QNX operating system
The structure of QNX. Kernel services, scheduling, interrupt mechanism, network handling. Creating embedded systems using QNX. QNX from the view of an end user. Application development for QNX operating system.
