Introduction to Real-Time Systems

Here is where it all starts! We will make a brave attempt to start your future career in real-time systems! This week starts by learning the basic building stones in real-time systems and the system parameters required to successfully construct a real-time system. We introduce you to the corner stone of real-time systems, namely the scheduler – and its task in real-time schedules. You learn also what kind of real-time guarantees are needed in which systems. Concretely, you will learn (1) What is needed to create a real-time system (2) Where real-time requirements are needed. (3) The task and job structure and the parameters needed to schedule a task. (4) Difference between pre-emptive and non-pre-emptive tasks. This course is also part of a Blended Master Programme in Embedded Systems. ...

Static Scheduling

In this week we start to actually do some scheduling. We firstly have a look at the simplest type of scheduler – the clock driven scheduler. After this we deepen our learning with the fixed priority scheduler and the monotonic schedulers. We learn how the priorities are determined using these schedulers and we learn when/when not to use these schedulers. Secondly we learn how to determine if a system is overloaded in order to validate schedules without complete system simulation.Concretely, after attending this week you will be able to: (1) Schedule a set of tasks with the clock driven scheduler, with the fixed priority scheduler, with the monotonic schedulers. (2) Determine if a system is overloaded using the total-utilization method and the Urm method. (3) Program FreeRTOS to schedule a set of tasks using the fixed priority scheduler ...

Dynamic Scheduling

In the previous week we learned the limitations of the total-utilization method and the Urm method. We start this week off by extending these tests to tasks with short response times. The new method is also, as usual, used in practice! We then focus on improving the optimality of real-time schedules. This is done by learning the principles behind dynamic scheduling methods. Two new schedulers using the dynamic scheduling principle is learned and used in practice with a few examples; the LST scheduler and the EDF scheduler.Concretely, you will learn: (1) How to determine feasibility of a set of tasks using the time demand analysis method. (2) How to schedule a set of tasks using LST and EDF. (3) To determine when a dynamic scheduler is appropriate and when it is not appropriate....

Non-Periodic Jobs

All things are easy and nice when not caring about non-periodic jobs. When including non-periodic jobs, the schedulers must take these into account to make a feasible schedule, which we learn this week. The problem is that a non-periodic job can arrive at any time, even if a periodic job is already scheduled. We learn both how to optimize a schedule for non-periodic jobs and how to validate a schedule when non-periodic jobs arrive to the schedule. Concretely, we will learn: (1) How to use the slack stealing method to optimize a schedule with non-periodic jobs (2) How to use the LRT scheduler to optimize a schedule with non-periodic jobs (3) How to use the deferrable server to optimize a schedule with non-periodic jobs (4) Formally verify a schedule with non-periodic jobs ...

Real-Time systems are very demanded nowadays. Excellent course to review some aspects in this field or to learn everything from the beginning.

par GTApr 23rd 2018

I feel having in depth analysis on various scheduling algorithms would be helpful. I have learnt many things from this course.

À propos de la Spécialisation Development of Secure Embedded Systems

Three people died after the crash landing of an Asiana Airlines aircraft from Seoul, Korea, at San Fransisco International Airport (SFO) on July 6, 2013. The American National Transportation Safety Board (NTSB) established that the crash most probably was caused by the flight crew's (in)actions. Three teenage girls lost their lives; two in the airplane and another was accidentally run over by a firetruck. The human factor is often cause for accidents. NTSB and others report that more than 50 percent of plane crashes is caused by pilot error (and for road accidents it is even 90 perc.) Correctly designed safety and security critical systems can prevent these errors. After following this course successfully, you are able to develop secure embedded systems that are at the core of these safety and security critical systems. You are even challenged to program your own landing guiding system in our capstone project. If you are interested in building secure embedded systems for the benefit of humanity, this specialization is for you! EIT Digital has chosen 3 MOOC topics of industrial interest, namely: 1) Embedded design and hardware, 2) Security in embedded connectivity and 3) Real-Time systems. These MOOCs show what it takes to program Internet-of-Things systems. We focus on tools used in the modern IoT industry, and we push for a practical learn-by-programming approach in which you are exposed to the actual development in an early stage. We hope to see you soon!...

  • Lorsque vous vous inscrivez au cours, vous bénéficiez d'un accès à tous les cours de la Spécialisation, et vous obtenez un Certificat lorsque vous avez réussi. Votre Certificat électronique est alors ajouté à votre page Accomplissements. À partir de cette page, vous pouvez imprimer votre Certificat ou l'ajouter à votre profil LinkedIn. Si vous souhaitez seulement lire et visualiser le contenu du cours, vous pouvez accéder gratuitement au cours en tant qu'auditeur libre.

  • We like to keep the exercise a bit more like in the industrial life: there is no "correct" answer but your task is to make the customer (peer reviewer) satisfied. Therefore we have other student review your solution and if that "customer" finds it acceptable, you will get a good score. Like in many engineering projects, there is no "correct solution" but there are many correct ways of implementing your solution.
