An embedded system is a system designed specifically for controlling purposes, fulfilling requirements of cost, size, consumption, validations and other features that make it suitable to be immersed in a required environment .

The objective of this course is to show what an embedded system is, specifying the functional requirements of an embedded system and how to evaluate it. The subject will give an introduction to design and develop systems, applications and services in embedded systems and ubiquitous. The aims is to provide enough elements of judgement to select the most appropriate hardware and software platforms that meet the specified requirements.

Teaching methodology

There will be no distinction between theory and problem classes, the theoretical classes will be reinforced with examples showing possible alternatives and solutions to the problems posed.
Self-assessment exercises will be proposed in the different topics so that the student can be aware of his progress, and can request help from the teacher in the event that he detects any deficiency.
The practical sessions will be held in the department's teaching laboratory. It is an essential requirement to have carried out previous work that will be specified for each of the practices.

Evaluation methodology

During the course, 2 theory and problem assessable tests will be carried out, corresponding to different parts of the course. They will be carried out individually. A theory grade (NT) will be obtained from the weighted average of the assessments.

* Only exceptionally will a final exam be taken, from which the grade NT will be obtained. The student who wishes to be assessed through a final exam must request it in writing to the subject coordinator before the first assessment test.

* The NL laboratory grade is obtained from the average of the individual assessments of the practices. 5 assessable practices will be carried out during the course. Repeating students who have passed the practices can validate the practices with NL=5.

* Throughout the development of the subject, students must present a work proposal, a pre-project and a design of an embedded system chosen by the group members. This design will be defended by the group in an act open to the entire class. The grade for these three acts will be NPF.

* The final grade (NF) of the subject is obtained from the theory grade NT, the laboratory grade NL and the final presentation grade NPF.

NF = 0.4 NT + 0.4 NL + 0.2 NPF.

* It is a necessary condition to pass the subject to carry out and present the laboratory practices in the form and within the established deadline.
