CppCon 2015

C++11 introduced Variadic Templates, constexpr Functions and Literal Types that ease and allow type-safe computations at compile time. For embedded development this is an important aspect, because it provides a means to create ROMable data in type-safe C++.

In combination with C++14 mechanism of Variable Templates, that actually defines constants, and the relaxed constexpr function rules there are unprecedented possibilities for compile-time computations.

This talk does not only show the mechanisms available but also demonstrates non-trivial examples, how they can be used to compute interesting data at compile time.
