NUCLEO L053R8 Benches

This repository contains code to measure the performance of embedded C and Rust code for an STM32 Microcontroller, specifically the STM32L053R on a NUCLEO-L053R evaluation board.

It implements a variety of algorithms in both C and Rust (crate/algorithms). These Algorithm programs are then executed by the executable program written in Rust. C code is called using Rust's FFI with manually implemented bindings. To measure the actual runtime of the algorithms, you need to attach an oscilluscope to the configured port of the board while the prgrams are running.

Dependencies

In addition to some crates from crates.io, this project requires the following to be installed to compile and link to the algorithms-c implementations.

# on debian bookworm
apt install binutils-arm-none-eabi gcc-arm-none-eabi # compiler for the target architecture
apt install ruby # ceedling is the used build system for algorithms-c, and needs to be installed with gem, the ruby package manager
gem install ceedling

Acknowledgements

For implementing the SHA-2-256 Algorithm, this website was very helpful.

The algorithms themselves are mostly reference implementation of various RFCs.
