ForEmb: A Forth-Inspired, Real-Time Interpreter for Embedded Systems

ForEmb, a real-time interpreter, was implemented and ported to various systems, including a Raspberry Pi Pico board, the design process of the interpreter is described in detail. ForEmb successfully simulated an information signal -using sine, cosine and exponential functions- with an absolute error percentage of 0.18% compared to the response of MATLAB and a variance of 1.06×10
⁻⁸
. The CMP and CKP sensor signals for Neon 2.0 L engine were also emulated by implementing them into ForEmb running on a RP2040 microcontroller; experimental measurements of injection timing validate real-time implementation.
