L4是第一个由Jochen Liedtke二发达

代码说明：

L4是最先由Jochen Liedtke开发的第二代微内核。目前，它已经变成了第二代微内核 的一个标准，基于这个标准，有很多L4 API的实现。其中一个实现就是Fiasco，它是在 德国德累斯顿大学开发的。为了强调Fiasco跟L4之间的这种关系，我们把Fiasco一般 称L4/Fiasco。L4/Fiasco与其它L4的实现不同的是L4/Fiasco是一个具有实时特性的微内 核，L4/Fiasco是DROPS项目的一个核心子项目，它同时提供了很多软件包，以方便 基于L4/Fiasco的程序设计。-L4 is the first developed by Jochen Liedtke second-generation micro-kernel. Currently, it has become a second-generation micro-kernel of a standard, based on this standard, there are many realize the L4 API. One is to realize Fiasco, it was developed at the University of Dresden, Germany. Fiasco with in order to emphasize the relationship between the L4, we Fiasco general said L4/Fiasco. L4/Fiasco with other L4 realize the difference is L4/Fiasco is a real-time characteristics of the micro-kernel, L4/Fiasco is DROPS a core sub-projects, it also provides a lot of software packages to facilitate L4/Fiasco based on the program design.
