First Rust applications for Autosar Classic

Functional safety First Rust applications for Autosar Classic

2024-08-07 From Sven Prawitz | Translated by AI 1 min Reading Time

The companies Vector and Hightec have developed functional safety applications with Rust and Autosar Classic. The compiler is compatible with C/C++ code.

Vector and Hightec Computer Systems have integrated Rust applications with C-based Autosar Classic base software. According to the companies, this is the first time this has been achieved worldwide. Embedded developers can thus use the Rust programming language with its advantages for functional safety applications in control units.

According to Vector, the advantages of Rust are the features for memory safety and error-free concurrency while maintaining very high performance. This is intended to minimize safety risks, shorten development cycles, and reduce costs.

Compatible with C/C++ code

Vector has combined its base software "Microsar Classic Safe" with the compiler tools from Hightec in the project. Infineon Aurix TC3x and TC4x are used as microcontrollers. Hightec is the first provider of an ASIL-D qualified Rust compiler for the Aurix microcontrollers. The base software and the compilers are safety-certified according to ISO 26262 up to ASIL D.

Like with C/C++, the compiler uses the open source technology LLVM, "Low Level Virtual Machine". Therefore, developers should be able to combine new Rust code with existing C/C++ code.
