    Teaching methodology

    The subject has laboratory classes only. A brief lecture lasting about 20 minutes is given at the start of each class. The lecture is designed to remind students of concepts learnt in previous subjects and to present the task to be carried out in the laboratory in detail.
    Laboratory classes are held once a week.

    In the autumn semester (S1) the embedded system prototype is designed and built, details on which will be given in the lecture, with the help of a microcontroller development environment and prototype implementation techniques.

    In the spring semester (S2) the processor shown in the lectures is implemented in an FPGA development board in the laboratory using professional development tools.

    The implementations and designs are done in groups of two.

    Evaluation methodology

    (S1) - Embedded system design and implementation project

    The final mark (NF) is the sum of the following three components:

    NF = 20% NP1 + 40% NP2 + 40% NP3
    · The NP1 mark is for the tasks carried out in the project's specification stage (initial stage of the project).
    · The NP2 mark is for the implementation and integration of the system's hardware and software (intermediate and advanced stages of the project).
    · The NP3 mark is for the results obtained compared with the specifications and objectives stated at the start of the course (final stage of the project).

    The marks for cross-disciplinary competencies are based on the following.
    Entrepreneurship and innovation: initiative in finding innovative solutions and the originality of these solutions.

    Teamwork: coordination of the work group and coordination among groups when shared design and implementation decisions are taken.

    Effective oral and written communication: the project report and its oral presentation. The oral presentation takes place outside class hours (in hours for directed activities) at the end of the course.



    (S2) - Processor implementation project

    The final mark (NF) is the sum of the following three components:

    NF = 5% NP1 + 75% NP2 + 20% NP3
    · The NP1 mark is for the tasks carried out in the tools and techniques learning stage (initial stage of the project).
    · The NP2 mark is for the implementation of the processor (intermediate and advanced stages of the project).
    · The NP3 mark is for the proposal and implementation of processor improvements (final stage of the project).

    Each of the NP2 and NP3 marks will be based on the submission and demonstration of the design implemented and the submission of a report on the project.

    The marks for cross-disciplinary competencies in entrepreneurship and innovation and teamwork are based on the proposals presented in the advanced stage of the project and the results obtained.

    The marks for cross-disciplinary competencies in effective oral and written communication are for a written assignment on the topics covered and a brief oral presentation. The presentation takes place outside class hours (in hours for directed activities) at the end of the course.

    The following grades will be awarded for the cross-disciplinary competencies: A, B, C or D (Excellent, Good, Pass or Fail, respectively).
