VTOS:一个支持多核的微内核操作系统设计与实现

VTOS: Design and Implementation of a Micro-Kernel OS with Multicore Support

现在处理器的发展已经进入了一个新的时代,继承了几十乃至上百个核心的处理器已经出现。这在大大提升了硬件处理能力的同时,也给软件设计,尤其是操作系统设计带来了很大困难。为了提高系统的可扩展性,操作系统开发人员需要花费大量的精力来进行严谨而有效率的同步设计。由于宏内核自身的复杂性,在进行同步设计时很困难。阐述了一个微内核的多核同步设计方案,由此可以发现在设计多核操作系统时微内核系统先天的巨大优势。

As the emerging of processors with hundreds ot cores, we are, performance, it also brings great challenge to the design of software, especially OS. OS developers need to spend much ef- fort in synchronization design to improve system scalability, Because of it＇s complexity, the synchronization design for mono-kernel is very hard. The authors present a synchronization design for a micro-kernel system in this article. We found that it＇s much easy compared with mono-kernel systems.
