Embedded C++, MISRA and AUTOSAR C++14
In March 2017, AUTOSAR presented guidelines for the use of the
C++14 language in critical and safety-related systems. These rules are essentially an extension of the MISRA C++ rules of 2008. In January 2019 Misra announced that the Misra C++ and Autosar rules will be combined to a common set of rules based on C++17.
This seminar is a thorough presentation of the C++ features allowed in AUTOSAR C++14 (especially C++11, C++14 and C++17). These rules hold for many embedded applications that are written in C++.

11. Polymorphic Memory Ressources (pmr), STL Containers and AUTOSAR C++
The standard allocators of STL containers
Tracking new and delete
Allocators and polymorphic memory resources

- Allocators in C++17
About „Embedded C++ and AUTOSAR C++ 14“
Software developers who want to write professional programs for embedded applications with C++.
Background knowledge: Good C and C++ knowledge.
Lecture with many examples. A balanced combination of theory and practice.
- At the beginning of a new topic, an overview of applications, basic ideas and syntax is given.
- The concepts and the syntax are illustrated by using carefully selected and proven examples. Often, best practices“ are presented.
- The manuscript contains numerous practical exercises.
- If desired, tasks from the work of the students can also be dealt with. This should be arranged before the start of the training.
Extensive and detailed training materials (approx. 200 pages) – Full text, no PowerPoint slides containing only keywords. Therefore, the course materials can also be used as a reference at work.
Time and place, online or face to face
This seminar is offered as an inhouse seminar (at your site). The implementation as a face-to-face seminar is preferred, but is also possible as an online seminar. Dates by arrangement.
