amforth is an extendable command interpreter running on AVR ATmega and TI MSP430 microcontrollers. The Risc-V and ARM architectures are ascending. Turnkey actions for IoT workloads are possible as well. The command language is close to the Forth 2012 standard.
SDCC-M08 is a Freeware, retargettable, optimizing ANSI - C compiler. New port for Motorola 68HC08/68HC908 processor family, a side branch of the original SDCC. It generates RAM sparing reentrant code, different from root SDCC. Distributed under GPL.
ELCO stands for Embedded Lisp COmpiler or Esdens Lisp COmpiler. The goal is to create a lisp compiler for embedded 32bit architectures. (i.e. ARM) With this compiler you are able to write lisp code on a naked chip. No OS needed.
