preemptive-multitasking

Event-driven, preemptive, priority-based, hardware RTOS for ARM Cortex-M.

A simple multitasking OS kernel

Demonstrate basic task scheduling method on LCD and STM32 Nucleo64 board. You will learn basic idea of OS multi-thread operation and C, Assembly code.

Hardware-assisted asynchronous micro-RTOS

Thread-Metric RTOS Test Suite

Bare metal preemptive multithreading for Raspberry Pi Zero 2 W

Binaries needed to run GordonOS - A pre-emptive multitasking OS for C64 (Requires REU, should work with C64 Ultimate), currently still 'work in progress'

Independent Linux kernel source tree — the low-latency "sunlight" variant. Being retired at 7.4; slkernel is the kernel path for the Sunlight Linux distribution from then on. Outside the repo-tool manifest by design.

On hold until further notice. Uses HertzScript coroutines to implement preemptively multitasked JavaScript Green threads.

Fault-tolerant kernel for deeply embedded systems

A pre-emptive multitasking OS for C64 (Requires REU, should work with C64 Ultimate), currently still 'work in progress'

Experimental C++ version of the magnesium framework

A real-time task scheduling simulator written in C++ accounting for cache related preemption delay on a unicore arhitecture.

A simple implementation of a preemptive multitasking kernel for the WRAMP processor, emphasizing the fundamentals of how multitasking works.

Real-Time Multi-tasking Pre-emptive Kernel for Embedded Systems

A tiny preemptive/cooperative RTOS for AVR (ATmega328) with static tasks in PROGMEM.

Hardware-assisted asynchronous micro-RTOS in Rust

Núcleo de SO didático em C, em espaço de usuário: threads sobre ucontext, dispatcher, escalonador por prioridade dinâmica com envelhecimento, preempção por timer de 1 ms, contabilização de tempo, task_wait e task_sleep. Disciplina de Sistemas Operacionais (UFPR) — esqueleto e testes do professor, núcleo implementado por mim.

Retro Mod Operating System

experiments with bootable image of x86 and protected mode 32 bit code for the i386 platform written in assembler and c++ contains: * minimal assembler kernel supporting preemptive multitasking (1 KB) * sample toy application of a 2d game engine
