Ucore是一个很小的适于学习的操作系统，此“麻雀”包含虚存管理、进程管理、处理器调度、同步互斥、进程间通信、文件系统等主要内核功能，总的内核代码量（C+asm）不会超过5K行。充分体现了“小而全”的指导思想。 这是ucore的实验2：内存管理。实验目的：理解内存地址的转换和保护；理解页表的建立和使用方法；了解物理内存的管理方法；了解常用的减少碎片的方法；了解虚拟内存的管理方法。文件中包括源代码、实验指导书和实验报告。
-Ucore is a small operating system for learning, the Sparrow contains the virtual memory management, process management, processor scheduling, synchronization mutually exclusive, inter-process communication, file system and other major kernel functions, the total amount of kernel code ( C+ asm) no more than 5K lines. Fully embodies the small the guiding ideology. This is ucore in Experiment 2: memory management. Purpose: to understand the memory address translation and protection understand the page table creation and use understanding of the physical memory management understanding of the methods commonly used to reduce debris understanding of virtual memory management. File, including source code, test instructions and test reports. (2016-06-02, Unix_Linux, 1540KB, 下载3次)
本程序为自己在学习操作系统时独立根据书上所述的银行家算法制作而成，包括一个数组输入函数（Sr()），数组输出函数（Pr()）和一个判断函数（test()），并通过指针传递参数，可以自定义进程数目和资源种类数目（源程序限10个以内，可自行更改数组）。
注：本程序是在linux环境下通过gcc编译器编译成功的。若移植到windows环境下可能在汉字显示部分出现乱码。
This procedure for their own independence in learning, when the operating system on the basis of the book described in banker s algorithm produced, including an array of input function (Sr ()), array output function (Pr ()) and a judging function (test () ), and through pointer parameters, the process can customize the number and type of the number of resources (source 10 within limits, can make changes to the array). Note: This procedure is in the linux environment through the gcc compiler to compile successful. If transplanted into windows environment may display garbled characters.
