This course is delivered in co-operation with Doulos' training partner Feabhas, who specialise in training courses for real-time embedded developers.
Since its standardization in 1998, the support and use of C++ as an embedded programming language has grown significantly. However, until recently most C++ cross compilers were actually “Embedded C++” (EC++) compilers or were typically inefficient in the more advanced areas of the language. To date, a high proportion of programmers using C++ for embedded development have either been unable or have chosen not to use certain features of C++ due to fear of bloated, slow code with poor performance.
This course addresses the “fear, uncertainty and doubt” of using full C++. Specifically the course deals with : performance and memory considerations of polymorphic functions, exceptions and templates. In addition, complete coverage of the Standard Library, including the STL, are covered, again with the specifics of performance and memory models.
• To provide an understanding of the advanced aspects of the C++ programming language.
• To give you practical experience of writing efficient C++ code for real-time & embedded systems.
• To understand the impact different compilers have on performance.
