Summary
Students are introducing on base knowledge of real-time operating systems.
Students will be ready for practical analyzes using real-time operating systems (RTOS) for various applications, especially for control applications. They will be also ready to choice RTOS for the selected application and apply this RTOS. There are explaining special using practices in RT operating systems. In the last part are introducing real-time operating systems applications in embedded systems. In laboratory there are confirmed real-time attributes of RT operating systems on QNX operating system for personal computers. Students are testing also other real-time operating systems e.g. for embedded control system. This subject is suitable for students another branches of study, which want familiarize with real-time operating systems.

Additional study materials
Way of continuous check of knowledge in the course of semester
- Verification of study:
- One credit test and one individual tasks and one wasted individual project.
- Days of delivery individual works by WEB or writing documents (9th and 13th week or 13th week for project)
- Closing Test - writing part of examination.
- Theoretical part of test consist 15 questions, which verify global student's knowledge.
Practice part of test student prepares on computer. Total test time is 120 min.
-Study Classification.
- Exercise credits - student is classifying on base 1 test 0-10 points and 2 individual works 0-10 and 0-15 points or individual project 0-25 points. Award of 14th week. Condition for receiving is min. 10 points; maximum of receiving points is 35.
- Examination
- Writing part - Closing test - theoretical part 0-30 points, practical part 0-25 points, total 0-55 points.
- Oral part 0-10 point. Total classification 51-100 points according study rules.
