Intended learning outcomes (Knowledges, skills and competencies to be developed by the students)

Introduction to embedded systems programming, particularly in real-time systems (i.e., where temporal requirements are on par with functional requirements), with emphasis on those having limited computing resources.
Concurrent and parallel programming.
Role of the operating system (multitasking) in developing concurrent programming.
Software state machines: universal acceptors and timed automata.
Scheduling.
Importance of scheduling in meeting temporal requirements.
Computer platforms used: personal computer for prototyping and development, and Single Board Computer for deploying, with Linux OS, in C++.

Syllabus

Enbedded systems: definition, concepts, characteristics, security, robustness, autonomy.
Program organization for embedded systems: polled superloop, state driven, event dirven time triggered.
Sistemas embebidos de tempo real.
Realtime embedded systems.
Definition of realtime, task, multitask, priority, schedulling (in particular rate monotonic), comunication and synchronizations among threads, hardware for realtime systems, realtime operating systems, PThreads.
State machines: universal acceptor and timed automata.

Demonstration of the syllabus coherence with the UC intended learning outcomes

The laboratory works are about varied subjects whose nature allows to train the materials, in particular the state machines, the concurrent programming and the parallel programming.

Teaching methodologies

Theoretical-practical classes are intended for the exposition of the subject, resorting to the explanation of practical cases whenever possible.
In the laboratory classes students develop projects that allow them to train their acquired knowledge and develop their autonomous work capacities.

Demonstration of the teaching methodologies coherence with the curricular unit's intended learning outcomes

The UC is based on the permission that knowledge is apprehended when put into practice.
The work done within the laboratory component meets the characteristics and requirements necessary for the main themes of the UC to be trained.

Assessment methodologies and evidences

Distributed evaluation with tests and final exam.
Final grade = 50% laboratory work + 50% exam
Since:
Minimum exam mark or test mean = 9.5.
Minimum note of any laboratory work = 9.5.
Minimum final mark = 10.
Works: development of a solution in hardware and software, a report and a defense of the work done.

Attendance system

The CTSP student regulation applies.
