The course focuses on the basics of the operating systems architecture, with a particular emphasis on operating systems for embedded systems, along with their corresponding development frameworks. The course will also cover issues related with real-time embedded systems and their communication with dedicated hardware components.
Risultati di apprendimento attesi
• Knowledge of the kernel structure and organization of an operating system
• Knowledge of virtual memory mechanism
• Knowledge of process scheduling and parallel execution threads
• Skill for using system calls for the creation, synchronization and termination of processes and threads
• Skill to understand device drivers
• Skill to understand and implement programs based on system calls
• Skill for using embedded systems development tools: cross-compilers, emulators, debuggers, profilers, virtualizers.

The slides used for the course will be made available to the students, through the official page of the course on the web site.

The textbooks are the following:

• Tanenbaum, Bos, "Modern Operating Systems", 4th Edition, Pearson, 2015
Criteri, regole e procedure per l'esame
The examination consists of a written test and an oral verification.

The written test (duration of 120 minutes with closed books) consists of two parts:
• 4 exercises/questions on the topics of the lectures (4 points each exercise)
• the solution to a problem using threads or concurrent programming in C language (16 points).
Students can access to the oral exam only if the evaluation of the written exam is higher than 17.
The oral verification will be on the topics of the lectures and on the verification of the program developed at the written exam. For the verification of the program, the student will have to provide the debugged and running code.
The oral exam contributes to the final grade modifying the evaluation of the written exam in a range of ±4 points.
The verification will be organized as a discussion in front of a PC where the student will be asked to:
– Compile/Build the software
– Run the software
– Explain a piece of code taken at random from the source files
– Possibly explain how and where to modify the code to change one of the program functionalities
– Discuss the results.
