Open Source Operating System Kernels - Page 3

ManRiX is an open source microkernel based operating system with POSIX interface. It is written from scratch using C and Assembly. Microkernel contains just few basic components of an Operating System while others are implemented as user process.

A kernel for your device

With this project I intend to write a really, really simple OS, just for fun and learning. I think I will never have a really usable version, as I said, that's no my objective.

A port of the Linux kernel and tools to the iPod.

The NitrOS-9 Project provides an OS-9/6809 compatible operating system for the Tandy/TRS-80 Color Computer and Dragon home computer.

A operating system designed to be compatable with the linux and uinx software, that is capable of running as a modern operating system.

EduOS is a GPL'ed, educational Operating System. Unlike most OSes currently in dev (i.e. Linux, Solaris, Unix, MacOSX) EduOS is desigend to be a educational resource for programmers new and interested in OS development. It's not designed for the end-us

The project maily focuses on integrating H.264 on IBM CELL platform.

Mark3 is a sophisticated RTOS and embedded systems toolkit, targeted towards a growing list of MCUs. Beyond providing "just another scheduler", it provides heaps, drivers, a shell, an event-driven GUI framework, and much more! It currently supports a variety of Atmel AVR, MSP430, and the ARM Cortex-M series of microcontrollers, with other platforms to follow. Mark3 was designed from the ground-up using disciplined object-oriented design principles - and unlike the vast majority of free or commercial RTOS' is written in C++, with bindings for C-language compatibility. The carefully designed object model drastically reduces the overall size and complexity of the source code, leading to enhanced code reuse, stability, and modularity. It also makes the source easier to understand - any experienced C/C++ developer should be able to understand the relationship between objects in the system, as well as use and extend them to fit a given application.

UEFI GPT fdisk is a port to UEFI of the famous GPT fdisk partitioning tool, see http://sourceforge.net/projects/gptfdisk/ . Now since this program runs directly under UEFI shell you don't need to *boot* the system to convert/edit partition tables.

A simple Embedded System Framework that allows rapid development of applications build for AVR family. System is based on a super-loop architecture with check and skip (no-wait) flag event driver system. 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. Awards CodeProject 2010, Third Prize, Hardware and Device Programming Check the Wiki Page for more details.

TORO is demonstrating an innovative operating system by integrating at the same ring level both kernel and the user application server. The threads of the user application server are distributed evenly on all CPUs and running independently in parallel. The memory model chosen is NUMA without pagination. During the initialization, the memory is divided proportionally for each processor installed on the system. When a thread needs memory, the memory allocator returns a free block of memory depending on which CPU the thread is running. In the same way, TORO can dedicate resources to specific processor, i.e. a FileSystem. This only CPU then can access to this instance of FileSystem. The scheduler is based on the cooperative threading model, therefore due to this design, TORO can migrate threads between CPUs and send messages between threads without using any lock instruction. TORO is well suited for integrated system to run at high pace application servers like web servers.

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.

A Trivial Operating System for 8051 (ATOS51). ATOS51 is a trivial operating system for 8051 microcontroller. As its name, it provides only multitasking feature.

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

GUSI (Grand Unified Socket Interface) is a POSIX/Pthreads/Sockets library bringing some of the comforts of UNIX 98 to traditional MacOS (7.0 - 9.9999).

LUnix (little UNIX) is an operating system for the Commodore64 - a famous home computer back in the 80s. It supports TCP/IP networking (SLIP or PPP using a RS232 interface). LUnix aims to look and feel like UNIX.

MikeOS is a an open source 16-bit operating system for x86 PCs, written in assembly language, which boots from a floppy disk or CD-ROM. It is designed as a learning tool for x86 assembler and basic OS design.

MinopsOS is a tiny operating system for PC computers. It's small enough to fit inside the boot sector of a floppy disk.

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.

Sets out to be an innovative new operating system while retaining compatibility with POSIX and Win32

TinyOS is an operating system for embedded sensors and networks. Versions 2.0 and later of TinyOS should be downloaded from www.tinyos.net.

AvRtos is a small, preemtive, priority based real time operating system for Atmel AVR and ARM microcontrollers. It was written in C. AvRtos provides message queues and semaphores for task synchronization. It uses a static memory allocation scheme. AvRtos is nearly the smallest RTOS out there. Even pico]OS is much bigger. AvRtos can be compiled using gcc compiler. There is a AvrStudio 4 and Eclipse project file to get the example code working very quickly.

This project aims to develop a Lisp based operating system for general purpose computer architectures.
