Hardware/Software Co-Assurance using the Rust Programming Language and ACL2

The Rust programming language has garnered significant interest and use as a modern, type-safe, memory-safe, potentially formally analyzable language. Our in stems from its potential hardware/software co-assurance language, with application to critical systems such autonomous vehicles. We report on the first known of High-Level Synthesis (HLS) Most incumbent HLS languages are subset C. A Rust-based brings single memory-safe expression for both hardware software realizations high assurance. As study suitability an HLS, we have crafted subset, inspired by Russinoff's Restricted Algorithmic C (RAC), which imaginatively named Rust, or RAR. In our implementation RAR toolchain, simply transpile source into RAC. By so doing, leverage number existing tools minimum investment time effort. this paper, describe detail prototype verification several representative algorithms data structures written RAR, proofs correctness conducted using ACL2 theorem prover.
