Compilers and development environments
The adoption of C++ in embedded systems was influenced by compiler support. While most compilers supported C, the support for C++ was slower. Nowadays, there is a variety of compilers and toolchains available for C++ depending on the target architecture and functional safety requirements. Support for 32-bit architecture such as Arm Cortex-M is generally good, but the level of support depends on the toolchain vendor and functional safety requirements.
Many vendors offer functional safety versions of their tools that include certified compilers according to the safety standards for different industries. Functional safety standards are designed to ensure that software operates correctly and safely, even in the event of hardware failures or operational errors. IEC 61508 is the international umbrella safety standard for functional safety, and the following are safety standards for some industries:
- ISO 26262: Automotive safety standard...
