Open Source C Operating System Kernels

The goal of the project is now to develop a user library called libpfm4 to help setup performance events for use with the perf_events Linux kernel interface. The development of the perfmon kernel subsystem, libpfm and pfmon has now stopped.

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.

DOS/32 Advanced DOS Extender is a drop-in replacement for the DOS/4GW DOS Extender and compatibles. Being fast, small and flexible DOS/32A can be used in many environments, from embedded systems to DOS emulators, by both developers and end users alike.

This project is for the portable computer "Cambridge Z88", produced by Sir Clive Sinclair (of ZX Spectrum fame). We continue to support software development (ROM, 3rd party apps on memory cards and desktop applications). We have moved to https://cambridgez88.jira.com/wiki (development, source code and documentation). However, we continue to publish files for download here.

The openwince project collects free (open source) software tools, modules, applications, drivers, and so on for Windows CE platform developers. Some of the modules are usable outside Windows CE development environment and are platform independent.

SkyEye is a very fast full system simulator which takes llvm as IR of dynmic compiled framework.. It can simulate series ARM, Coldfire,Mips, Powerpc, Sparc, x86, TI DSP and Blackfin DSP Processor. Also can simulate multicore system by the multicore of host. The commercial support is provided by DigiProto Co. (http://www.digiproto.com)

TempleOS is a 64-bit kernel with compiler, graphics library and tools. It is not a Unix. It was made from scratch.

Plus operating system is hobby project. That's built to run as auxiliary OS with Major OS like Windows and Linux etc..bootable with grub2 and own boot loader.focused on eBook reading software(PDF,EPUB,MOBI,DJVU,CHM...).with programs like calculator, notepad,source code editor, hex viewer, text viewer,image viewer and many games.VESA 32bpp GUI from startup.read-only plus maybe writing support for standard file systems FAT/NTFS/EXT/CDFS.codec for archives(ZIP,RAR,7z,GZ ...).codec for image formats(JPG,BMP,GIF,PNG...).video player or at least thumbnails extract(AVI,MKV,MP4,3GP...). mountable as filesystem from ISO,ISZ file.generic drivers VBE,USB,HD Audio,Keyboard, mouse.bootable on qemu and of course on real computer systems.at least all drivers for one computer (my) this is primary goal. In summary goal is building a stable and usefull OS. A Project By Arshad Latti. Support PlusOS project on patreon https://www.patreon.com/arshadlatti to encourage.

An easy to use Development Environment for OS developers to design, write, compile, test, and publish new or existing OS projects with ease.

POSIX API for Win2K-XP. Mainly implemented in the driver. Included: write-on-copy fork, threads, mutexes, spins, condvars, rwlocks, signals ... Signals/cancelation interrupt all waitable syscalls, NT syscalls are automaticaly restarted.

kissme is a free (GPLed) Java Virtual Machine. It is being developed on GNU/Linux and can run console java applications. kissme is to be used with the GNU Classpath java class library. kissme also provides support for orthogonally persistent java.

While I may have started with Linux 0.11, I've expanded this to include several older relases of the Linux kernel that you can cross compile from Windows, and run on Qemu. I've managed to get the older versions of the software tools running on Windows, so that there is no major invasive source changes, outside of either broken drivers, or massaging the makefiles to find things in the new paths, and calling the appropriate tools where needed. Linux 0.10 is the first oldest version of Linux that is somewhat usable. While it lacks things like TCP/IP, and robust filesystems, it does offer a small kernel size, perfect for playing around with. You can comfortably make changes on Windows, re-compile and test all from a 'normal' desktop.

SuperWaba is a Virtual Machine for handhelds. Runs in PalmOS, Windows CE, Win32, and is fully emulated under JDK/browser. Supports Exceptions, has a complete set of UI controls (Palm/WinCE), double and long, grayscale/color, sockets/serial/IR/Bluetooth

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.

We intend to provide a development system for the Rabbit2000/3000 microcontrollers. On Linux: a cross C-compiler, assembler, linker chain. On the rabbit: a BIOS including download and debugging facilities. Later a realtime kernel + TCP/IP stack

Your Ass Os is an Operation system kernel. Whole written in C and assembly, need supporters.

The extensor, is a assembly of programs and independent libs (- nostdinc) at the moment for DJGPP, but thought for others GCC-i386. By means of this kit it is possible to construct a operating systems or a program boot from the BIOS (i386 embedded syste

Affnity is a hobby operating system, to help it's developer(s) understand the concepts of operating systems development and low level programming in C, C++, assembly.

**DISCONTINUED** 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

The Bella Operating System aims to use currently available source code as a bootstrap to create a new "Media Operating System" primarily aimed at mid to upperlevel emebbed devices, such as Set Top Boxes and Pocket PCs.

This project contains test software and tutorials for Analog Devices' Blackfin DSP device drivers and system services. See the wiki (in the menu bar above) for more info.

The goal of this project is to provide an operating system with a native GUI, an interpreter for an object-oriented BASIC dialect and many more features to make life easier for normal users.

DRAKE is a true homebrew game console that consists of specially crafted hardware, system software and games.

The project is not more active, we have fix a lot of issue and perform many improvements. These are now deliverd as part of a new project: https://github.com/ciaa/Firmware ---- FreeOSEK is a scalable solution for embedded system. FreeOSEK OS is based on OSEK RTOS specification (OSEK-VDX). visit us in: http://opensek.sourceforge.net
