The course aims at introducing basic concepts of hardware and firmware architectures of computing systems, starting from digital circuit fundamentals up to the description of behavior and structure of the main parts of a computing system and its programming in machine language.
Expected learning outcomes
The student will have to demonstrate understanding of role and behavior of basic elements related to structure and functioning of a computer. The student will have also to be able to translate simple algorithms into the machine language of the reference processor adopted in the course.
Lesson period: Second four month period

Assessment methods and Criteria
The exam is constituted by a written test (requiring solution of application exercises and answer to theoretical questions) evaluated in thirtieths, and by the coding (in computer lab) of a program written in LC2 Assembly language that - if correct - may lead to a maximum increment of 2 thertieths of the grade obtained in the written test.
