Development of Real-Time 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

Course Description

This course is intended for the Master's student and computer engineer who likes practical programming and problem solving!After completing this course, you will have the knowledge to plan and set-up a real-time system both on paper and in practice.The course centers around the problem of achieving timing correctness in embedded systems, which means to guarantee that the system reacts within the real-time requirements.Examples of such systems include airbags, emergency breaks, avionics, and also multi-media systems like video playback and QoS in web servers.The course teaches how to plan real-time systems in theory using established mathematical proofs and how to implement them in practice by using the most common scheduling methods.We also learn and how to program the system in the C language using the FreeRTOS real-time kernel.Finally we have a look at the future of real-time systems namely multi-core real-time systems!This course focus on the learn-by-doing approach with many examples and real-world programming assignments.We have 5 modules, each with a gentle graded quiz in the end and one peer reviewed programming assignment.In case you have no experience with C programming, please check you a practical course like:https://www.coursera.org/learn/arduino-platformThe course is actually quite fun!-Simon Holmbacka / Abo Akademi UniversityCheck out our whole curriculum: https://research.it.abo.fi/

This course assumes that you are familiar with freeRTOS.

By John O O on 19-Jun-16

The course feels pretty shallow and it ignores all the interesting stuff like proofs. There is no written material available, so if you can't follow the lectures, poor you. Quizzes aren't very well formulated and sometimes the correct answer is more of a matter of opinion rather than a hard fact. Evaluation seems to be based solely on peer review and there are no model solutions available, so the points you'll get may vary depending on how your peers understood the assignment and if they were interested in the review process at all.My overall feeling is that nothing was quite challenging on the course, and I didn't learn much more than what I could have learnt by reading a few paragraphs per topic from Wikipedia. I also felt that the programming assignments were quite disjoint from the core, tough I don't feel like I understand the core better than before the course because none of the assignments made me think why something works, rather than that we just mechanically reproduced the examples shown in the lectures.

The assignments are quite poor. They need to improve that.

By Rajyavardhan S on 8-Oct-19

The content is really very rich but the problem is that it is not consistent in terms of quizzes with assignments and videos.I think that being a peer graded assignment, it takes a lot of time to get a grade.

By Feiyu L on 9-Oct-17

Assignments are quite vague in instructions and more in depth coverage on RTOS application in assignments would be more helpful.

By Vaibhav j on 16-Jun-17

Good structure but poor contents.

By DaeMyung K on 7-Nov-16

The contents of the course are interesting, but it feels too short, and the assignments trend to let you down (the scoring system is sometimes a bit brainless)

By Kerran F on 20-Oct-17

No guidance for a FreeRtos and this makes programming assignment too tough for a newbie

By Qiuxiang D on 7-Nov-16

Very useful course with good information. Current iteration is a little rough as an online course, could use a little thought into the peer-review process works specifically around how to distribute the code.

By Jean-Baptiste B on 12-Sep-19

It was good amount of leaning new things related to RTOS. This course gives you knowledge to design and choose the RTOS based on your requirement of the project.

By frierys on 23-Nov-18

I recommend this course to developers who want to get understanding about RTOS and work with it .. the videos is so short that you can get boring like other courses and the assigments are really hlpfull.thanks so much to EIT Digital online university and special thanks to Dr. Simon who gave a brief explaination to the topics

Too goooood!!
