Computer Architecture I
A.Y. 2025/2026
Learning objectives
The course introduces the principles at the base of a computer; simple logic gates are first presented, and then combined, thought a succession of intermediate abstraction layers, into the design of ALU firmware and of a MIPS architecture, capable of executing programs with a core machine language.
Expected learning outcomes
The student will be familiar with the basic principles underlying the processing of digital information. In particular, (s)he will have the skills needed to understand, analyze and design
combinatorial and sequential circuits.

Course syllabus
For the theory part:
- introduction to the course topics, objectives, and organization;
- representation and logical processing of information: binary representation for natural, integer, and real numbers, binary functions, and Boolean algebra;
- physical representation and processing of information: logic gates and truth tables;
- synthesis of binary functions with combinational circuits, building an arithmetic-logic unit (ALU);
- storing information: sequential logic elements (bistable, latch, clock synchronization);
- synthesis of sequential circuits, finite state machines;
- design of a single-cycle CPU and outline of the multi-cycle case;
For the laboratory part, besides an introductory tutorial on the adopted software tools, sessions will cover:
- binary coding;
- combinatorial logic (canonical forms, critical path);
- advanced combinatorial logic (multiplication, ALU);
- sequential logic (Memories, finite state machines);
The theory and laboratory parts are carried out in parallel. The beginning of the lab sessions is usually delayed of one/two weeks.

None.
Teaching methods
The theory part is given with frontal lectures where slides are presented. Slides are made available in PDF format through the Ariel platform.
The laboratory part proposes guided exercising sessions at the PC. The adopted software tools and the exercises (instructions and selected solutions) are made available through the Ariel platform.
Attendance is recommended for both the theory and the laboratory part.

Teaching Resources
Course website on the myAriel platform.
Slides, exercises, and other supplementary materials will be provided.
Both the theory and the laboratory part are based on the topics covered in: "Computer Organization & Design: The Hardware/Software Interface" by David A. Patterson and John L. Hennessy, Morgan Kaufmann Publishers.

Assessment methods and Criteria
For the theory part, there will be a written test lasting 3 hours at most where the resolution of an adequate number of exercises is proposed. Each exercise involves the application of the principles and techniques presented during the lectures. During the exam, consulting any material is forbidden.
For the laboratory part, the exam consists of carrying out some proposed exercises on the PC and lasts about 1 hour. Each exercise involves the construction of a digital circuit according to specific functional requirements. During the exam, specific material approved by the teacher can be consulted.
Both tests, theory, and laboratory result in a grade out of thirty which is communicated through the Ariel platform (optionally also by email). If both grades are greater than or equal to 18, the exam is passed with a grade equal to the weighted average of the theory grade (weight 2/3) and the laboratory grade (weight 1/3). The two tests can be passed in different exam sessions but in a time span of at most 6 months or three successive exam sessions (choosing the less restrictive of the two).
The assessments will take into account: confidence in applying techniques, correctness, and elegance of the solutions, clarity of presentation. The tests and their assessments will not be differentiated on the basis of attendance.
