Modern C++ (C++20/23) for Embedded

Overview

Modern C++ standards bringing concepts, modules, and improved constexpr capabilities to embedded development. Enhanced compile-time computation reduces runtime overhead.

Benefits

• Improved type safety with concepts
• Better compile-time optimization
• Reduced template error complexity
• Enhanced constexpr capabilities

Limitations & Risks

• Compiler support varies across embedded toolchains
• Increased compilation times
• Learning curve for legacy C++ teams

Recommended Actions

Evaluate compiler support for target platforms, establish coding standards for modern features, train teams on new capabilities

Additional Notes

GCC and Clang support is mature, but some embedded-specific toolchains lag behind
