The ARM-Ada project provide ravenscar runtime system and some useful libraries for deeply embedded applications written in gcc ada (gnat) language. For now RTS port for lpc21xx is done.
Simple AVR OS
An Embedded System simple Operating System Framework that allows rapid development of applications build for AVR family but can be ported to other architectures easily enough. System is Round-Robin Co-operative multitasking. Supports: UART, SysTick Timer, ADC, SPI, EEPROM, PWM. Also supports: Xilinx FPGA configuration, FPGA SSI interface, smart card reader etc. Tested partially (different modules in each case) on ATMega163/16/32/323/8. Additionally tools for converting FPGA bitstreams to C table are provided.
Agnix is an educational, network operating system kernel. It is ideal starting point to learn about operating systems. The main goal of the project is to provide a network kernel fully compatible with the Linux Kernel in the system call layer
Arm mini real-time OS, cooperative kernel for LPC 2106, Arm TDMI-s cores.
BOS – B.lu operating System, is an operating system dedicated to small microcontrollers and CPUs without MMU. Actually is dedicated to Texas Instruments MSP430 microcontrollers (it can be ported to other CPUs without great changes)
fast single-privilege single-address-space preemptive-multithreading persistent data-centric secure multiuser operating system with safe-language and reconfigurable graphical interface
A Development Framework for Coldfire
Contains a framework for Coldfire MCUs like 52254. The framework supports a Command Line Interface (CLI) that may work from Serial port, USB or ENET. The framework uses Processor Expert and IDE requirement is MCU Eclipse 10.4 from Freescale. Includes the FunkOS Realtime Operating System by Funkenstein Software Consulting, available at http://funkos.sourceforge.net Mainly it is a support package for the development board Perseus, but I have ported also the RTOS to MCF52233DEMO board. More to come....
An open source operating system for x86.
Cellocity Linux is Based on Fedora Core 6 Source Code. With only basic core elements needed to operate Compatipal and a completley Graphic Interface as well as Text. Version 2.0 will include more applications 32,64 bit and 80 Core Intel CPU
ChibiOS/RT is a free and efficient RTOS designed for deeply embedded applications. It offers a comprehensive set of kernel primitives and supports many architectures: ARM7, Cortex-M0, Cortex-M3, Cortex-M4, PowerPC e200z, STM8, AVR, MSP430, ColdFire, H8S, x86.
The CodeTime platform covers every aspect of parallel software from authoring, through distribution, to run-time. Its goals are: high programmer productivity; write once, run high performance anywhere; and wide acceptance.
What is EROS? Energy Resonance Open Source is an energy related developer environment for Ozone-Friendly Solutions. These Developer Collaboration Sites (DC's) promote energy-based DC applications and extensions as a kernel for major operating systems
DRAKE is a true homebrew game console that consists of specially crafted hardware, system software and games.
The Danber project aims to create an operating system where both Windows and Linux programs can be run: it is a Windows NT based kernel, but with UNIX user mode compatibility. Support for both PE and ELF executable formats.
The future of information technology will be based on controlling the flow of natural light. This project is an attempt to establish the code (or software) that will enable this to happen. It involves rewriting an OS from the ground up.
This was originally an OSdev group, but since as members disbanded, I'm continuing to provide various implemenatitions of software, hardware, operating systems, libraries, and some stuff related to math and physics.
Fortress OS is an open source modern multitasking operating system. Intel IA-32 386 compatibility. Fortress is clean implemented from scratch. Fortress is still in early stage ( current state at the end of plan 2 ) and needs huge work.
Operating Sytem x64
Operating System x64 write in nasm for intel CPU. (+ HackOS in graphic mode) (Full description are in two projects (readme.txt))
Haiku is an open-source operating system currently in development designed from the ground up for desktop computing.
JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.
Javum, the Java Virtual Unix Machine, is an ambitious project which aims to provide a full virtualized Unix environment including C compiler (GCC), Unix-like API, shell, and command line tools, inside of a JVM. Details @ http://javum.wiki.sourceforge.net
K-OS is an open-source realtime-operating-system based on the OSEK/VDX standard aimed at compiler and microcontroller independence. Currently we support Motorola (Freescale) HC12/HCS12/HCS12X targets.
This project aims to develop a Lisp based operating system for general purpose computer architectures.
A FOSS operating system that aims to meet NSA's TPEP TCB A1 evaluation standard while retaining application compatibility at minimal performance overhead.
Overnet Millennium Server for Unix Linux
Linux C/C++ Bash Shell developers we need you!!! Overnet Millennium Server for Unix/Linux adds a whole new layer to the web, the Overnet . With the Overnet Millennium Server web hosts will be able to offer a new space and protocol to deliver data to a web browser in a completely new way. Web developers will have a totally new way to create content for the web. And web users will have thousands of new services, sources of entertainment and ways to communicate, as well as the power to organize, talk, play, and work with fewer clicks, and more efficiency. OMeS is the worlds first truly web 3.0 server and it will change the way you view the internet and perhaps your world.
