RUST Development Platform
The automotive industry has taken a significant step forward with the introduction of the first ISO 26262 ASIL D qualified Rust Compiler Development Platform for Infineon AURIX by HighTec. This milestone marks a crucial move towards enhanced security, safety, and efficiency in automotive software development.
The rapidly evolving landscape of Software-Defined Vehicles (SDVs) presents several challenges, including security, complexity, and cost-effectiveness. To address these challenges, the industry is shifting towards secure, safer, and more efficient programming solutions. Rust, a memory-safe programming language, offers major advantages over traditional languages by minimizing security risks, shortening development cycles, and reducing costs.
One of the primary benefits of Rust is its memory safety features, which prevent common errors such as null pointer dereferences, data races, and buffer overflows. This is achieved through Rust's ownership model, which ensures that memory is managed safely and efficiently. Additionally, Rust's compile-time checks and borrow checker prevent many types of errors at compile-time, reducing the need for runtime checks and resulting in faster execution.
Rust also provides concurrency support, allowing developers to write concurrent code that is both safe and efficient. This is particularly important in automotive software development, where real-time systems require predictable and reliable performance. Furthermore, Rust's interoperability features enable seamless integration with existing C and C++ codebases, making it an ideal choice for hybrid development approaches.
The HighTec Rust Compiler, specifically designed for AURIX TC3x and TC4x microcontrollers, leverages advanced open-source LLVM technology to deliver the full range of Rust language features. These features include memory safety, concurrency, and interoperability, making it ideal for applications with strict requirements regarding safety, security, high-performance, and rapid deployment.
HighTec's pioneering effort in qualifying the Rust compiler goes beyond language conformity, complementing its successful C/C++ compiler for Infineon AURIX microcontrollers, which is also ASIL D qualified according to ISO 26262. Both compilers are built on cutting-edge LLVM open-source technology, providing a unified toolchain solution that allows seamless integration of newly developed Rust code with legacy C/C++ code or a hybrid development approach.
This hybrid approach enables software developers to identify critical functions in terms of security, rewrite that part in Rust, and integrate it into their overall system. For instance, developers can rewrite a specific function in Rust to enhance security and then integrate it with the rest of the system written in C/C++. This approach enables a more efficient and secure development process.
By adopting Rust, automotive software developers can benefit from improved code quality, reduced maintenance costs, and enhanced security. Rust's modern design and syntax also make it an attractive choice for new developers, reducing the learning curve and increasing productivity.
