С++ в embedded
Myths about C++. Some of the perceptions that discourage the use of C++ in embedded systems are:
C++ is slow.
C++ produces bloated machine code.
Objects are large.
Virtual functions are slow.
C++ isn’t ROMable.
Class libraries make large binaries.
Abstraction leads to inefficiency.
Most of these ideas are wrong. When the details of C++ code generation are examined in detail, hopefully it will be clear what the reality behind these myths is.
