Course detail

Real-Time Systems (in English)

FIT-RTSaAcad. year: 2023/2024

Lectures of the course do present the problem of developing a real-time system complexly, in its full breadth and depth. They pay a special attention to comprehensibility and practical applicability of presented topics as well as to linking fundamental knowledge together. The topics are supported by case studies of real-time systems from various application domains (automotive, avionics, defense, vision, robotics, power and energy etc.), case studies of timed development means (specification and verification means and tools, platforms, programming languages, operating systems) as well as problems, their causes and solutions. Students will become acquainted with fundamentals and complexity of such a development and will be able to cope with typical development problems. Dedicated exercises allow students to gain basic skills to solve such problems. Students can deepen their skills further, through the semestral project.

  • Following activities are monitored: the attendance and activity during lectures, exercises and the progress of project-related works.
  • A prospective reimbursement of absences caused by an obstacle in the study is going to be realized according to the nature of the obstacle and lessons involved, e.g. by setting a substitute term or assigning a separate (homework) task. A solution to other kind of absence is not arranged herein, i.e., it is neither excluded nor guaranteed.

Aims

To introduce and explore concepts, principles, methods and instruments as well as problems related to development of real-time systems, from their specification to their practical application. To provide students with a theoretical background and an understanding of the practical engineering issues raised by the development of real-time systems. To support the taught facts by real-world case studies, to motivate students to understand causes of problems and to discuss solutions of the problems. To give students knowledge and skills to develop a real-time system by practicing the gained knowledge during dedicated exercises and project topics.
Students will get a general overview in the area of real-time systems and their development as well as in the area of real-time extensions of conventional, typically untimed, development means. Students will be able to specify requirements imposed on a real-time system, to model it and check its properties, to construct such a system by appropriate means (a hardware platform, operating system etc.) and to test it in operating conditions. Students will understand the principles and complexity of developing a (digital) system which meets the requirements for (continuous) real-time.
The students will be able to cope with the development cycle of real, typically hidden embedded cyber-physical, systems (such as engine or ABS control in a car, control of road/railway junctions and crossings, control of autonomous, adaptive, cooperative and/or collaborative systems) they may encounter in their everyday life. The students will link, deepen and extend their knowledge and skills from various, typically isolated, information technology areas (such as modeling and analysis, hardware, software, dependability, operating systems and languages) and will be able to see the areas from new perspectives.
