一个微型操作系统源码-a micro-source operating system

MAC OS X操作系统开发者手册！ -MAC OS X operating system developers manual!

EOS是一个主要用于教学的开源操作系统，它的源码风格是windows内核风格。EOS的整体结构简单，从boot、loader、kernel.dll到应用程序，结构清晰简单，但是功能内核功能也比较完整，源码总数为10000多行，比较适合初中级操作系统内核源码学习者。 与Linux0.11或0.12相比，EOS的内核的结构更加的模块化，结构比之清晰，是学习操作系统原理与内核分析研究的较好的工具。 -EOS is a major open-source operating system for teaching, and its style is windows kernel source code style. EOS" s overall structure is simple, from the boot, loader, kernel.dll to the application, the structure clear and straightforward, but the function of the kernel functions are relatively complete, a total of more than 10,000 source lines, more suitable for middle-class operating system kernel source code learners. 0.12, compared with Linux0.11 or, EOS of the core structure of a more modular structure than the clear, is to learn principles and core analysis of the operating system a better tool.

本项目是一款内存动态分区分配模拟程序。用户通过本程序可以了解动态分区分配方式中使用的数据结构和分配算法，加深对动态分区存储管理方式及其实现过程的理解。-The project is a dynamic partitioning of memory allocation simulation program. Users through the process can understand the dynamic partition allocation methods used in data structure and distribution of algorithms, understanding of dynamic partitioning storage management approach and its realization process of understanding.

一个完成的lru算法-a completed LRU algorithm

线程同步机制。 互斥器的功能和临界区域很相似。区别是：Mutex所花费的时间比Critical Section多的多，但是Mutex是核心对象(Event、Semaphore也是)，可以跨进程使用，而且等待一个被锁住的Mutex可以设定TIMEOUT，不会像Critical Section那样无法得知临界区域的情况，而一直死等。-Thread synchronization mechanism. Mutex" s function and the critical region is very similar. The difference is: Mutex spent more time than the multi-Critical Section, but the Mutex is the core object (Event, Semaphore is), you can cross-process use, and has been locked waiting for a Mutex can be set to TIMEOUT, not as Critical Section did not know the critical situation in the region, for so long and so die.
