=简介= Bycore是一个年轻的嵌入式操作系统内核，2009年2月28日正式以GPL版权的形式公布。任何人都可以在非商业目的前提下任意地获取、发布它的源代码。 Bycore还只是一个简单的系统，离真正的实用还有很远的路要走。但Bycore的目的是出于有用，如果您是名教师，您可以使用Bycore协助您完成操作系统之类的课程。如果您是名学生，Bycore也将帮助您了解更多计算机的核心技术。如果您是名工程师，Bycore也将被完善成为能帮助您解决实际问题的系统。总之，Bycore的最终目的是能够给您实际的帮助。 Bycore目前实现了内存管理、任务管理、中断管理、任务互斥、同步与通信...

= EKOS = 简易的操作系统计划 目前已经实现和支持的功能有： * a exokernel-like design * paging management * user space * queued inter process communication * local RPC (X) * signal handling (broken) * fork(copy on write) and __dumb-fork__ (broken) * preemptive multitasking * user heap (broken =.=) ...

This is an experimental OS focus specially on studying for PowerPC machines. The initial codes are mostly *stolen* from u-boot. Yes, I just want to learn some technics about how to implement an operating system on the PowerPC machines. So I grabed some of the existing/establised codes from some well...

Eliax is an excuse to develop an operating system. It is designed to work on x86 platforms, and is intended to support paging, multi-tasking, task protection, and multiple file systems(which means at least 2). The plan is to divide the kernel into 4 parts: memory management, file systems, device dri...

Arctic OS is a partially experimental operating environment. It's main purpose is to take advantage of newer Intel technologies and try to spin a new perspective on the way kernel's are designed. The project is under the M.I.T. license and is open for developers to contribute to. Current fea...

=HostOS= HostOS aims to be a powerful virtual machine, running as a host for other operating systems. As this OS does not have most of the unnecessary weight other kernels do, it is hoped that it will be ideal for multiple OS visualization. This should overcome the hurdles which face most OSes ...

FreeNOS is an experimental operating system written for one purpose: learning and exploring computer systems. For this reason, the FreeNOS project emphasizes: * Readable Code: The number one rule. It's impossible to learn from a system with unreadable code. Additionally, the purpose of high leve...
