`foci` is a small Forth implementation that prioritizes performance and portability. This threaded Forth implementation uses CPU registers and native execution to maximize efficiency.
Register usage is the only platform-specific requirement; otherwise, `foci` is written in 100% portable C. There is active support for x86\_64, ARM Cortex-M, and MSP430 architectures.
`foci` compiles to a binary object that can easily be linked into another application. Code size is less than 5 kB, while RAM usage is in the hundreds of bytes (primarily influenced by the configured stack and dictionary sizes).
