Moss Kernel is an open-source operating system kernel project designed to explore modern OS design and provide a foundation for experimental system research and development. Rather than replicating traditional monolithic kernels exactly, it emphasizes modularity, safety, and simplicity by incorporating well-structured subsystems for memory management, scheduling, and device abstraction that are easy for contributors to understand and extend. The kernel uses Rust as its primary implementation...

Pharos is a free open-source RTOS for secure, safe and real-time systems with the following characteristics: - Memory and enhanced time partitioning (TSP) - Native support for sporadic, periodic and aperiodic threads - Fixed-priority preemptive scheduler - Execution time protection (threads are prevented from executing for more time than they are configured to) - Small size (full image has ~100 to 300KiB text, ~30KiB data) - Hard real-time determinism - Fast critical sections -...

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...

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...

"µOS++" (micro OS plus plus) is an open source, royalty-free, real-time operating system intended for embedded systems built around ARM Cortex M or AVR devices. It is based on a preemptive scheduler written in C++ (more info in the Wiki).

qtOS is an operating system for running systems of finite-state machines. The system kernel is a task scheduler that runs processes' transitions at every cycle. Each task is activated either to be run in parallel (fork) with other active processes in the system or subordinated to the caller task, thus blocking it and creating a hierarchy of tasks. Execution of processes can be preemptive or non-preemptive and, among those with the same priority, a round-robin turn is performed. This...

Mini Vezer OS (MVOS) is a minimal footprint simple embedded OS-like task scheduler implementing cross-task communication, primarily designed for the Freescale HCS08 microcontroller.

Note: the project is basically dead, as I started rewriting it but I don't have much free time to work on it. It's basically a micro-kernel, but on top of that, instead of having multiple servers running as standalone processes, it has a modular kernel, so that each server is a module of this kernel. The micro-kernel contains only the scheduler, memory management and drivers for high-speed devices (like gigabit ethernet NICs or video cards).

homeOS is a cross-platform operating system, currently has a scheduler and some basic infrastructure for x86 and arm.

Helium is a minimalistic real-time scheduler for 8 and 32-Bit microcontrollers. The current version of Helium has been ported for Freescale's HCS08 and Coldfire cores.

Scheduler for MC68HC908 family µP. Modify 10/01/2007.

The Hierarchical Loadable Schedulers (HLS) framework is a scheduling infrastructure for hierarchically composing soft real-time schedulers. Each scheduler only communicates with other schedulers and the HLS infrastructure according to a well defined i
