The course is organized in two modules: 24-hour lecture and 24-hour codesign lab tutorials (lecture room 24, on mondays and wednesdays, 3-5 pm)

Acquisition of the subject concepts and methods is supported by:

• attendance to lectures and problem solving
• participation to lab experiences
• study of reference readings
• consultation of supplementary readings
• experience with software tools and development platforms for embedded systems
• working out solutions to proposed problems and exercises, see Test area
• writing reports on lab experiences, in the same area
• interaction with teacher, weekly schedule:
  • G. Scollo: room 325 (I block, II floor) [phone]ext.: [095738]3007
    on mondays and wednesdays, 1-3 pm
• collaborative interaction with colleagues and teacher

Lectures: the study of the recommended readings sets the methodological grounds for effective application of a technology-transverse, result-unitary design approach:

• versatile design of systems with optimal figure of merit that are dedicated to perform highly specialized tasks

Exercises: starting from a specification of the abstract functionalities of the system, the first problem which is often faced with is to select an architecture wherein to map them out, in order to further proceed to the synthesis of all components: hardware, software, communication interfaces. The proposed exercises deal with the different parts of this process.

Codesign lab: it is envisaged the use of development boards and platforms to implement embedded applications, ranging from on-board configuration to FPGA-based synthesis of components, up to System-on-chip (SoC) implementation. Reports on lab experiences may be outcomes of collaborative group work.

Seminars: as an experimental feature, some lectures (max. 1/5 of the total) take the form of seminars that are prepared and delivered by students; planning of the seminars is carried out as part of a lab tutorial.

Oral exam, project (optional)

• evaluation objectives
  • oral exam:
    assessment of the achievement of educational goals
  • optional project:
    assessment of conceptual and scientific maturity exhibited in the practice of the subject
• oral colloquies
  • assessment of critical learning of the subject
  • evaluation of individual contribution to lab experience reports
  • (optional) colloquy on individual use of subject concepts and methods within an original lab project, previously agreed with the teacher, that may be the outcome of a collaborative group effort
• exam schedule

Exam success yields the acquisition of 6 credits.
