The goal of this course is introducing the student the main concepts related to the design and implementation of systems with time requirements, that is to say real-time systems. In order to achieve this goal, the student has to acquire a set of general competences, knowledge, capacities, and attitudes, Basic Competences: CB1.- Students have demonstrated knowledge and understanding in a study area of the base of general secondary education, and is typically at a level that, whilst supported by advanced textbooks, includes some aspects that implies knowledge of the state of the art of their field of study. Specific Competences for Computing Engineering Mention CEIC2.- Ability to develop specific processors, embedded systems and software development/optimization of such systems. Along with the following program outcomes: a, c, d, e, g, i, j, k General/transversal competences: - Analysis and synthesis capacities. (PO a) - Abilities to organize and plan. (PO a) - Problem solving abilities. (PO c) - Teamwork. (PO d) - Capacity to apply theoretical concepts. (PO a, c) Specific competences: - Cognitive (Knowledge) (PO a) 1. To understand the specific concepts and problems related to real¿time systems and the differentiated aspects with other computational systems. 2. To know the most important methods used to implement real-time systems, to know the way their software is organized, and to understand the principles and the deployment process. 3. To know scheduling aspects in real-time systems. 4. To know the functionality in real-time systems, their architecture and inner behavior. 5. To know some important tools (programming languages, and operating systems) suitable for developing real-time systems. 6. To know the existing alternatives for building microprocessor-based systems for embedded environments. 7. To know the techniques for developing against specific processors and for embedded systems. 8. To know the methods to analyze, evaluate and select the embedded and real-time hardware/software platforms. - Procedimental /Instrumental (Know how) (PO e, g, j, k) 1. To design and to evaluate a real-time systems. 2. Capacity to analyze Cyclic real-time schedulers and rate monotonic priority-based real-time schedulers and to check the correctness of a real-time application. 3. To design and to implement real-time applications by using real-time operating systems. 4. Capacity to design and to build microprocessor-based systems for embedded environments and real-time systems. 5. Capacity to design and to implement systems using specific processors and embedded systems. 6. Capacity to analyze, to evaluate and to select the embedded and real-time hardware/software platforms. 7. To use tools (programming languages and operating systems) suitable for developing distributed real-time systems, checking their temporal correctness - Attitudinal (PO c, i) 1. Capacity to generate new ideas (creativity) 2. Critical attitude towards the internal architecture of current real-time systems. 3. Concern for the quality of the real-time system. 4. Motivation to investigate for solutions to new problems related to the design of operating systems. 5. Learning capacity and achivement motivation.

Learning activities and methodology
Theoretical lectures: 1.5 ECTS. To achieve the specific cognitive competences of the course. They present the knowledge that students should acquire. In order to take advantage of these lectures, students will have the and the list of basic books used as bibliography. Thus, students could complete the information given in lectures and take a deeper vision those materials they are interesting in. (CB1, CEIC2 and POs a, j) Practical lectures: 1.5 ECTS. To develop the specific instrumental competences and most of the general competences such as teamwork, capacity to apply theoretical concepts, planning and organizing, analysis and synthesis. Besides, to develop the specific attitudinal competences. During the practical lectures, a real-time application is designed and developed using cyclic task scheduling and priority task scheduling. Also some embedded environments are evaluated. They are developed by groups of students and on computer classrooms, with a teacher tutoring the classes (CB1, CEIC2 and POs a, c, d, e ,g , i, j, k) Guided academic activities (present teacher): 1 ECTS (CB1, CEIC2 and POs a, c, d, e, g, i, j, k) - By solving exercises and case of studies in a participatory way. It can include the study of examples of real-time operating systems, collaborative resolution of exercises, collaborative answers corrections, presentation of works, etc. Student¿s work: 1.5 ECTS. (CB1, CEIC2 and POs a, i, j) - Exercises and complementary text reading proposed by the teacher. - Personal study. Exercises and examination: 0.5 ECTS. It goal is to influence and complement the development of the cognitive specific capacities and procedural skills. (CB1, CEIC2 and POs a, c, e, g)
