用C语言编写和调试一个简单的进程调度程序

Nuttx 是一个实时嵌入式操作系统（Embedded RTOS），它很小巧，在微控制器环境中使用。Nuttx完全可扩展，可从从小型（8位）至中型嵌入式（32位）系统。它的设计目的还在于完全符合POSIX标准，完全实时，并完全开放。

Bochs is a highly portable open source IA-32 (x86) PC emulator written in C++, that runs on most popular platforms. It includes emulation of the Intel x86 CPU, common I/O devices, and a custom BIOS. Currently, Bochs can be compiled to emulate a 386, 486, Pentium, Pentium Pro or AMD64 CPU, including optional MMX, SSE, SSE2 and 3DNow! instructions. Bochs is capable of running most Operating Systems inside the emulation including Linux, DOS, Windows 95/98 and Windows NT/2000. Bochs was written by Kevin Lawton and is currently maintained by the Bochs project at "http://bochs.sourceforge.net".

线程的调度模拟ok-thread scheduling simulation ok

一、实验内容1． 设计和实现一个模拟文件系统，要求包括目录、普通文件和文件的存储。必须有自定义的数据结构，不能直接调用windows 的API函数，即不能只实现了一个壳。2． 文件系统的目录结构采用类似Linux的树状结构。3． 要求模拟的操作包括：a) 目录的添加、删除、重命名；b) 目录的显示（列表）；c) 文件的添加、删除、重命名；d) 文件和目录的拷贝；e) 文件的读写操作。 请点击左侧文件开始预览 ！预览只提供20%的代码片段，完整代码需下载后查看 加载中 侵权举报
