Bjarne Stroustrup’s FAQ<\/a> makes it crystal clear. One of the design goals for C++11 was to make C++ even better for the embedded world.<\/p>\n

<\/p>\n

 <\/p>\n

Or to say it in the words of Bjarne Stroustrup, inventor of C++: “Improve performance and ability to work directly with hardware — make C++ even better for embedded systems programming and high-performance computation.”<\/p>\n

\"BjarneStroustrup\"<\/p>\n

I reasoned a lot about this sentence because I changed from software development in the middleware area into the embedded world. I was responsible for the software on defibrillators. So I started my search for the kind of features in C++11 that are particularly well suited for embedded programming. I presented my search results at conferences<\/a> in Berlin, Munich, and Sindelfingen.<\/p>\n<\/p>\n

In the meantime, my perception of the new features as user-defined literals, the type-traits library, or constant expressions has changed a lot. They are such great features that they belong in the toolbox of each professional C++ developer. This statement is even more true for the embedded world because they have to deal with stronger requirements. Therefore, the posts about “Embedded programming with C++” are particularly valuable in embedded programming.<\/p>\n

What’s the reason for my perception? The answer is simple. There is no typical embedded system. The diversity is large. There is RFID<\/a> transponder about the size of a few millimeters, pacemakers that should work reliably for a longer period, defibrillators consisting of a few boards and even more CPUs that wait years for their application, or cars having more the 100 electronic control units (ECUs). The borders between the embedded systems and other systems as game development or low-level systems, are blurred.<\/p>\n

What makes embedded programming unique? Embedded programming is the more intensive programming. More intensive because it has to deal with strong requirements:<\/p>\n
