Subject aims expressed by acquired skills and competences
The aim of the course is to introduce students to advanced programming techniques in operating systems. In the course, students will get a practical introduction to the implementation of the basic elements of operating systems and file system mechanisms. Upon completion of the course, they will be able to design their programs efficiently to maximize the use of available operating system resources.
Upon completion of the course, students will be able to:
- Identify the different layers of an operating system and describe the main functions.
- Describe the internal processes of an OS with respect to the process life cycle.
- Create applications running directly on a specific system without the support of extension runtime libraries.
- Modify software development practices to enable better use of system resources.

Lectures
- Operating system architecture, characteristics of mobile and embedded systems.
- Internal structure of operating systems, implementation of system calls and modules.
- Implementation of process management, concurrent processing. Signal handling and processing.
- Features of process schedulers, their setup, real-time (RT) processes.
- Power management, power saving and power planning techniques.
- Implementation of device drivers, communication with peripherals.
- Working with files and I/O devices. Memory mapped files.
- I/O operations synchronous and asynchronous; blocking vs. non-blocking mode.

- Implementation of a simple HTTP server.
- Multi-threaded server with interprocess/inter-thread synchronization.
- Implementation of a custom process scheduler with priorities and prevention of process starvation.
- Runtime monitoring of Round-robin (RR) and Lottery Scheduling (LS) schedulers, their comparison.
- Processes, signals and their capture and masking.
- Implementation of a simple file system (FS) in read-only mode.
- Extending the FS implementation to include writing, formatting and possible consistency checking.
- Monitoring of I/O device data flows and network interfaces.
