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.
Learning Outcomes of the Course Unit
The goal of subject is introduce students on base knowledge of real-time operating systems (RTOS). Students will be ready for practical analyzes using real-time operating systems for various applications, especially for control applications. They will be ready for choice of the real-time operating system for selected applications.
