OpenXL provides a flexible, platform-independent SOA/Web Service middleware and workflow programming language (SLL). OpenXL supports the creation, provisioning and execution of Web Services as well as the integration of code written in BPEL, Java, etc.
jRate is a real-time Java compiler and runtime system (based on GNU GCJ) with support for much of the Real-Time Specification for Java (RTSJ), including threading constructs with real-time constraints, asynchronous event handling, and memory regions.
ButterflyOS is a very simple operation system for the Atmel AVR Butterfly board. It's based on the AvrX multitasking scheduler, created by Larry Barello. A byte-code program for ButterflyOS, can be sent and managed through the serial interface.
Protoscribe converts pseudo English sentences in to Object Oriented code skeletons. It was developed to help teach object oriented design and as an experimental sourcecode generator. Currently, C++ and Java code skeletons can be generated.
Jack is an optimizing C compiler for the Jackal 3.0 ISA. The Jackal 3.0 ISA is the target architecture for UVa's Advanced Digital Design Course. JackCC is ready for production use. Additionally, I've written an assembler/simulator: jackas
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.
The purpose of this project is to modify SmartEiffel to allow it to be used to create applications for mobile device platforms such as Symbian, BREW, and J2ME. Currently the codebase is based on SmartEiffel 1.0, but we are looking into moving over to Sma
NasmSharp is an open source effort to build a x86 assembler written in pure C#. Primarily it is a C# port of well known x86 assembler NASM, written in ANSI C.
Involvement of some experienced C# programmers is highly appreciated.
zCOBOL portable mainframe COBOL compiler, part of the z390 project
The zCOBOL portable mainframe COBOL compiler with support for compiling multiple dialects of COBOL into any one of several target language executable programs including HLASM compatible mainframe assembler, Java, C++, or Intel assembler. All downloads and other information are kept at the z390 project site; see the home page link for more information.
SCOF provides a C/C++ toolchain that is easy to build, extend, and even embed within custom applications that wish to parse and interpret sourcecode.
It's goal is to be a C/C++ framework that is modular and easy to understand from beginning to end.
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.
