JCPP is a complete, compliant, standalone, pure Java implementation of the C preprocessor. It is intended to be of use to people writing C-style compilers in Java using tools like sablecc, antlr, JLex, CUP, and so forth. It has been used to successfully preprocess much of the source code of the GNU C library.
Data2l is a language neutral, platform neutral way for describing large sets of proprietary binary data. An example of this kind of data is car navigation data, which is about 1GB to 15GB in a typical embedded navigation. With Data2l you can easily describe almost any binary data format using primitive description blocks like basic type, array, structure, or alternative and using a functional dependency description language. Using such a description, one can generate source code optimized for certain tasks, like a lightweight data reading layer, fast querying code, or code suitable for data generation and transformation.
Neko is a high-level dynamically typed programming language. It can be used as an embedded scripting language. It has been designed to provide a common runtime for several different languages. Learning and using Neko is very easy. You can easily extend the language with C libraries. You can also write generators from your own language to Neko and then use the Neko Runtime to compile, run, and access existing libraries. Neko is a good way for language designers to focus on design and reuse a fast and well-designed runtime, as well as existing libraries for accessing filesystem, network, databases, XML, etc. It has a compiler and a virtual machine. The virtual machine is very lightweight and well optimized. The VM can be easily embedded into any application, and your libraries can be accessed using the C foreign function interface.
jRate is an extension of the GNU GCJ compiler front-end and runtime system that adds support for most of the features required by the Real-Time Specification for Java (RTSJ), including threading constructs with real-time constraints, asynchronous event handling, and memory regions. It was initially developed at Washington University in St. Louis and is released under a license similar to GCC's GPL license that allows non-GPLed programs to be compiled and linked.
nMicrocoder is an ncurses EDA tool to write microcode. Basically, it is a stripped down spreadsheet program that lets you fill a table with "0", "1", and "-", and gives you compile-ready verilog code in return. It was written as an alternative to full spreadsheet programs. It is known to run on Linux, IRIX, and Solaris, unless ncurses 5.3 is installed.
TIMES is a tool suite designed mainly for symbolic schedulability analysis and synthesis of executable code with predictable behaviors for real-time systems. Given a system design model consisting of a set of application tasks (required to meet mixed timing, precedence, and resource constraints), a network of timed automata describing the task arrival pattern and a preemptive or non-preemptive scheduling policy, TIMES will generate a scheduler, and calculate worst-case response times for the tasks. The design model may be further validated using a model checker and then compiled to executable C-code.
