Wouter van Ooijen argues against using traditional objects in resource-constrained embedded systems, proposing template-based alternatives.

On “Embedded C++ question regarding constructors”

…ke care that the objects stay around. For work that is time/size critical, I experiment with 'objects' that are in fact types (class or struct), and are passed as template parameters. This limits me to static relationships, but it eleminates all dangling reference problems, and the optimizer has full view of the call chains. A longer explanation: link to this video…

On “Future of embedded coding architecture”

Thanks for the "objects? No thanks" reference, I watched this video link to this video Even in that video, he mentions that for small MCU usually their compiler doesn't even support C++. But if it does, it might only support C++98 standard only and not the latest standards. But in any case, even he shows that assembly code generated by C was the smallest and we had to use compile time polymorphism using templates in C++ to achieve the same assembly code. Hence, proving my point that C++ dynamic polymorphism will generate less optimized code as compared to procedural C. Do you know any companies that are using compile time polymorphism with SOLID/Design patterns in their code base?
