GNU Prolog is a free implementation (under GPL) of the logic programming language PROLOG. It can compile to native machine code which is extremely fast in execution. Another feature is the included constraint solver.
amforth is an extendible interpreter on microcontrollers
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.
ELENA is a general-purpose, pure object-oriented language with late binding. It promotes more object-oriented program design, reusable and more standardized code. The package includes compiler, IDE, ELENA libraries and samples
colorForth is, in Chuck Moore's own words: "A dialect of Forth that uses color to replace punctuation. Includes its own operating system. Produces extremely compact programs. Instant compile from pre-parsed source."
FastSim consists of:
- 'Facile' a highly flexible and expressive processor-architecture specification-language.
- A compiler for the specifications which produces high-performance, fast-forwarding simulators.
fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface
CLISP is a portable ANSI Common Lisp implementation and development environment by Bruno Haible. Interpreter, compiler, debugger, CLOS, MOP, FFI, Unicode, sockets, CLX. UI in English, German, French, Spanish, Dutch, Russian, and Danish.

A Java 2 (JDK 1.3/1.4) compatible virtual machine. joeq is unique in that it is almost entirely implemented in Java, making it reliable and efficient. It is also language-independent, so code from any language can be seamlessly and dynamically compiled.
‘intelliworm’ is a prototype simulation of a Intelligent Species of a common earth worm,which inherits human like decision making capabilities through Neural Network intelligence representation,all developed by integrating .NET with Lisp and Yacc.
A compiler and cross-compiler for (Currently) Cobol (with Fortran being added later). It is intended to be the first self-hosted open-source Cobol Compiler, e.g. the compiler itself will be written using Cobol.
CDK4AVR stands for Cross Development Kit for Atmels AVR RISC processor serie
and should you support with a comprehensive Assembler and C development
environment for even this processor familie under Linux or similar host systems.
OpenDos is a software that optimizes the executables at run-time. This optimizer is aimed to optimize i386 executables of ELF format. It is entirely user-level software, which works on the native binaries.
CDK4NIOS stands for Cross Development Kit for Altera's soft core processor NIOS and should you support with a comprehensive Assembler and C/C++ development environment under Linux. It will present only free of fee tools, so you can use it without risks.
VirtuAL3101 provides a series of tools to develop effects using the AL3101 DSP from Alesis. It includes an assembler/disassembler, a simulator, an application generator with its graphical interface and various effects.
Project's goal is to investigate the possiblity of fully-dynamic programming in memory-constrained environment like microcontrollers using virtual machines and a language+virtual machine for some architectures.
MEDDAC is the seeding point for designing a new approach to Operating System design itself. It is an Open Source project with roots in mainframe design and development the author began in 1979. Monitor Editor Disassembler Decompiler Assembler Compiler
A library written in Objective-C for linux or others gcc-enabled systems that brings support of slots and signals ŕ-la Qt in the language, and a windowing toolkit made in OpenGL or X11. Other useful tools may also be included such as XML.
