Advances in Operating Systems
A.Y. 2021/2022
Learning objectives
The purpose of this course is to allow the student to understand and be able to manage the mechanisms underlying the operation and implementation of an operating system: levels of abstraction, synchronous / asynchronous event management, clock management, peripheral management, communication, concurrency primitives, management and communication between processes, security of hardware components.
The "theoretical" exposure of the various topics will be accompanied by laboratory lessons during which students will have the opportunity to experience the concepts acquired on a commercial micro controller (STM32 Nucleo) made available to students, for the duration of the course only, by the ST Microelectronics company.
The laboratory lessons will also represent an opportunity for students to:
deepen C programming, learn how to use an integrated development environment for a commercial embedded system, master the FreeRTOS operating system.

Prerequisites for admission
Knowledge of the C language can speed-up the comprehension of some of the arguments which will be treated in the course.
Teaching methods
The teaching will be carried out in the presence, the lessons will alternate the theory part with the laboratory activity.
The laboratory part will be carried out with the aid of an STM32 micro controller based on an ARM Cortex-M processor, and related development environment. The micro controller will be made available to students, who must undertake to return it intact at the end of the course. As the laboratory activity will take place in the classroom, students must be equipped with a PC on which the development environment for the micro controller must be installed.
There will also be seminars and interventions by experts from the world of work and research.

Assessment methods and Criteria
The final exam will consist of the development of a project that can be carried out in groups of at most 2 people.
The project will consist of a feasibility study as well as the practical realization of a system "driven" by an STM32 board or other micro controller chosen by the student. The project can be carried out both in bare programming or with the support of FreeRTOS.
The project will be evaluated following the following criteria:
10 points for the originality of the project
15 points for the complexity in terms of code size and implementation difficulties that had to be overcome
5 points completeness of the documentation presented to support the project
3 points effectiveness of the project exposure
