Learning Objectives

The course has two goals.

It introduces the knowledge of the technologies and methodologies for the design of digital systems at different levels of abstraction. The student learns to design combinatorial and sequential circuits and to design digital systems using HDL languages.

The second objective is the knowledge of the organization of a computing system, the architecture of the instruction set, and the techniques for an efficient implementation. In this context the student learns to evaluate the performance of a computer and the impact of architectural choices on performance. Moreover, the student lerns to program in the Assembly language of an educational processor.


Course Structure

The course will be organized in lectures, exercises, practical experiences and presentation of use cases.
