Computer Architecture
A.Y. 2024/2025
Learning objectives
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
Students are expected to master information encoding techniques, Boolean algebra, and key notions of logic circuits. They will have to demonstrate understanding of role and behavior of basic elements related to structure and functioning of a computer. Students will have also to be able to translate simple algorithms into the machine language of the reference processor adopted in the course.
Lesson period: First semester
Assessment methods: Esame
Assessment result: voto verbalizzato in trentesimi

Assessment methods and Criteria
The exam consists in
* a 60-minutes written test (evaluated in thirtieths) without possibility of consulting books or other didactic supports, with 3 open-answer questions aiming at evaluating the understanding and the personal rethinking of all topics presented in lectures, as well as all logical connections among the various, technological, functional and implementation dependent aspects of the computer architecture;
* a 60-minutes practical test in a PC lab (that - if correct - may lead to a maximum increment of 2 thirtieths of the grade obtained in the written test) requiring implementation and testing of a program written in LC2 Assembly language, to verify the understanding of the machine-level behavior of the computer.
Results will be publiched on the Ariel course website.
