Lush is a Lisp dialect with extensions for object-oriented and array-oriented programming. It is intended as a programming environment for prototyping numerically intensive applications. Unlike alternatives like Python or SciLab, Lush is designed for easy integration of existing C/C++/Fortran codes.
The libjit library implements just-in-time compilation functionality. Unlike other JITs, this one is designed to be independent of any particular virtual machine bytecode format or language. Currently, libjit is used as the JIT backend for the DotGNU Portable.NET project (in addition to its default CVM backend). However, the hope is that other Free Software projects can use this library rather than spending large amounts of time writing their own JIT from scratch.
SoCLib is a library of pluggable SystemC cycle-accurate and transaction-level components. The library contains many types of models: processor cores (MIPS32, PPC405, ARM-v6k, Nios2, MicroBlaze, lm32, etc.), memory types, devices (block device, UART, frame buffer, etc.) and network-on-chip models. SoCLib can be used to create a complete system-on-chip hardware design, as well as for testing and evaluating embedded operating systems and applications. NetBSD, MutekH, and other dedicated systems are ported to the SoCLib hardware simulator. A Linux port is an ongoing project.
CASampledSP is a JNI-based service provider for the javax.sound.sampled.spi interfaces. As such it is capable of decoding many popular audio formats (like mp3 and aac) at native speed taking advantage of Apple's CoreAudio library. The focus is currently on decoding and converting to LPCM, not on writing or exporting.
