Akalon is a Bare-Bones Embedded RTOS that's designed to be simple and portable to any Microprocessor or System (Board). Currently supports the Intel and ARM Architectures.
Clicker is a project for a Multitasking Open-source operating system written from scratch. based on a modular micro kernel. We want to explore new way of designing and using OSes :) [newz: PCI, NE2K and VBE]
Ace is a micro kernel for developers and researchers. The main goal is to create a very light and compact kernel from scratch with modern OS research concepts.
Written entirely in 8051 assembly this is a bare bones Real Time OS (RTOS) kernel for the P89C668 microcontroller. The OS itself is inspired by the discussion in 'MicroC/OS-II: The Real-Time Kernel' an excellent book by Jean J. Labrosse.
Deploy in 115+ regions with the modern database for every enterprise.
MongoDB Atlas gives you the freedom to build and run modern applications anywhere—across AWS, Azure, and Google Cloud. With global availability in over 115 regions, Atlas lets you deploy close to your users, meet compliance needs, and scale with confidence across any geography.
a kernel for many architectures. the kernel is a micro-kernel which can be used as an hybrid- or monolithic-kernel. the kernel is written in assembler and C.
Prex is a portable real-time operating system for embedded systems. The small, reliable and low power kernel is written in C language based on micro kernel design. File system, UNIX process and networking features are provided by user mode tasks.
A small micro operating system kernel written in C (and partly assembly).
Planned features are: software based preemptive multitasking/threading, paging, kernel API, IPC, client/server, security system.
The code is designed to be clearly understandable.
SIMDOS stands for SImple Microkernel Distributed Operating System. SIMDOS is a micro-kernel based operating system which implements the concepts of Distributed Shared Memory at the kernel level to provide seemless addition on cluster nodes.
SDL REFLEX is the micro kernel of a real time operating system for the AVR microcontroller family. The kernel is especially designed to implement systems described in SDL The Specification and Description Language . Compiler GNU ANSI-C for AVR v.3.3
Hadie - Hardware Abstracting Device Independent Environment. Or just another micro kernel for embedded devices.
Supported architecture are i8051 (80515c), i166 (XC161CJ), Tricore (TC1775B), m68k (m68332) and i386.
Micro-80 aims to simulate a Z80 homebrew computer down to the bare metal: 64K RAM, ADM-3A terminal, parallel port, serial port and...3.5" 1.44MB floppy drive?!
Based on an architecture that is a mix of exokernel and micro-kernel, ev/ros shall be an innovative and revolutionary operating system that will support many platforms and provide conventional, distributed, and hard real time features.
