Ell is a library to write EBNF grammars as C++ code for quick development of LL(n) parsers or similar applications. It is not a tool to generate parsers (like ANTLR): the grammar you write is directly embedded into your C++ code. The core library is very light (less than 2000 lines of headers) and written in generation templates to achieve the fastest execution. The service provided by Ell is very similar to what Boost Spirit provides, but with a simpler object model, and without the need of the Boost library (it only depends on STL).
PlugPBX is a prebuilt, ARM-based Debian system for end users to run Asterisk and FreePBX on the Marvell SheevaPlug low power platform. It includes Asterisk 1.6.1 with compiled DAHDI kernel mods, FreePBX 2.5, Apache2, MySQL, Samba, Munin, Webmin, Avahai, and OpenSSH. It is built on top of Debian Squeeze.
MutekH is a portable and free operating system for embedded platforms originally developed at the SoC department of the LIP6 Laboratory in Paris. MutekH is a set of libraries built on top of an exo-kernel designed to support heterogeneous multiprocessor platforms. MutekH is fully configurable to match every application's needs. It is used in several research projects and currently supports x86, arm, mips, and powerpc processors.
RT-Thread RTOS is a real-time operating system for 16-bit to 32-bit microcontrollers, with components which include a hard real-time kernel, a command line shell, a device virtual file system, and a graphic user interface. RT-Thread/GUI is a graphic user interface integrated with RT-Thread. It provides a multi-window, multi-thread graphic user interface. Rich widgets are implemented in RT-Thread/GUI, such as label, button, checkbox, textbox, etc. The typical RAM usage of RT-Thread/GUI is less than 20kB RAM.
InfinityDB is an all-Java B+Tree database engine that is embeddable in the smallest to the largest applications that run on hand held devices, workstations, servers, or in distributed systems. InfinityDB provides a data integrity guarantee through all non-media failures, provides a simple API with only a few basic methods, and requires no administrative support. Version 2 offers full ACID transactionality without a log and with fine-grained locks. Programmers can easily superimpose their own data model or employ the Entity-Attribute-Value model by direct low-level access. The basic engine provides multi-valued or set attributes, all primitive Java types, unlimited Large Objects, heterogenous values, composite keys (Entities) and values, and unlimited sparse attributes, all extensible in-place with no schema changes.
Paparazzi is powerful and versatile autopilot system for fixed-wing aircraft and multicopters. It comprises both hardware and software. The project includes not only the airborne hardware and software, from voltage regulators and GPS receivers to Kalman filtering code, but also a powerful and ever-expanding array of ground hardware and software including modems, antennas, and a highly evolved user-friendly ground control software interface.
Xvisor is a type-1 hypervisor that aims to provide a monolithic, light-weight, portable, and flexible virtualization solution for ARMv5, ARMv6, ARMv7a, ARMv7a-ve, ARMv8a, x86_64, and other CPU architectures. It primarily supports full virtualization, and hence supports a wide range of unmodified guest operating systems. Paravirtualization is optional and is supported in an architecture independent manner (such as VirtIO PCI/MMIO devices) to ensure that no changes are required in the guest OS.
sVimPy is a very small Python virtual machine intended for use in microcontroller projects. At the moment, it supports about 3/4 of all opcodes used in python3k. Most data types are supported. The intended goal is to use this VM in environments like Atmel's ATmega chips (2-8kb RAM). The microcontroller bootloader is still missing (no arduinos left for experimentation). Classes are not supported. Features include: function calling, a stack based VM, garbage collection, very low memory usage, an interactive debugging console, dictionaries and tuples, iterations, VM single stepping (game loop usage is possible), C function calling, a small memory footprint, fast performance, the ability to be used as a library in other projects, a simple API + code, possible usage as a small deployment executable for Python projects.
