The course is taught in English. This course is part of the Master Degree in Computer Engineering, focused on Embedded Systems, and it is eligible course for the Master Degree in Mechatronic Engineering. The course aims at deepening the concepts acquired during the Operating Systems course, describing the peculiarities of embedded systems, of the dedicated development tools, and outlining the peculiarities of some operating systems for embedded systems that are particularly relevant (process scheduler, OSEK/VDX, AUTOSAR, Linux). The course will also deepen the concepts of real-time embedded systems, and the issues of communications with ad-hoc hardware components.

- Concept of embedded system. - Understanding of the development tools for embedded systems: cross-compiler, emulator, debug tools, profiling tools, virtualization tools. - Concept of real-time embedded systems. - Understanding of examples of operating systems for embedded systems. - Skill for the development of modules for the communication with ad-hoc hardware components.

- Ability to develop programs in C language. - Knowledge of the architecture of computer-based systems: in particolar knowledge of processor architecture and memory organization. - Knowledge of the interrupt mechanisms, and basic knowledge of assembly programming.

Introduction to Embedded Systems (0.5 CFU) - Classification with respect to desktop systems. - Memory technology device. Development tools (0.5 CFU) - Cross-compiler. - Emulator. - Debugger. - Profiler. - Virtual platforms. Operating Systems for Embedded Systems (4 CFU) - Real time and process scheduling. - Analysis of the architecture and services offered by operating systems for embedded: process scheduler, VxWorks, OSEK/VDX, AUTOSAR, Linux. - Anatomy of an operating system for embedded systems. Programming of an embedded OSEK/VDX system (1 CFU): - I/O management, and device drivers. - Use of an evaluation board. - Building a OSEK/VDX operating system for embedded systems: how to use development tools. - Design and development of device drivers for custom devices.

The course is organized in lectures and exercises in class, and practical exercises in laboratory. The topics are presented during formal lectures/exercises in class, and then are addressed from the practical point of view in the following week.

... Exam Written exam lasting 60 minutes, closed books, composed of questions on the exam content, and numerical exercises to apply the theory presented in class. The maximum score for this part is 33. Assignment Students will be asked to deliver a group assignment (2 persons per group) to be developed during the semester, describing the activities done in lab. The maximum score for this part is 33. The final grade is obtained using the following weights: 70% for the written exam, 30% for the assignment. In case the final grade is 33/30, 30L will be recorded.
