SJF算法，最短优先算法，大家还是看看吧，同样帮修改一下阿，谢谢啦-SJF algorithm, the shortest priority algorithm, we still look at it, also changed a bit to help Ah, thank you

基于麦克风阵波束形成的谱相减方法在语音增强中的应用-Microphone array beamforming based on the spectral subtraction method speech enhancement application

本次程序的题目为：进程管理――支持多个进程并发运行的简单的进程管理模拟系统，对本实验的分析要求是：⑴系统中的同步机构采用信号量上的P、V操作的机制；⑵控制机构包括阻塞和唤醒操作；⑶时间片中断处理程序处理模拟的时间片中断；⑷进程调度程序负责为各进程分配处理机；⑸根据用户的需求来创建n个进程(n为即满足用户需求,又不超出系统可容的最大进程数),各进程互斥地访问使用临界资源 S1、S2；⑹使用动态优先数(如：随阻塞次数的增加而减小优先数，以提高其优先权)；⑺进程结束后应能够撤消；⑻进程间能实现“发送”和“接收”两个消息缓冲通信操作；⑼系统在运行过程中随机打印出各进程的状态变换过程、系统的调度过程及公共变量的变化情况，在一个进程运行完毕，进入完成状态后，可以将该进程撤消，也可以动态的创建另一个新的进程。-the procedures on the topic of : process management-- to support multiple concurrent processes running a simple process management simulation system for the analysis of the experimental requirements are : 1 system of institutions using synchronous signals on the amount of P, V operation of the mechanism; 2 control agencies, including obstruction and awaken operation ; 3-time interrupt handling procedures-time simulation of interruption; 4 process scheduler is responsible for the allocation process processors; together according to the user"s needs to create process n (n that meet user needs, without exceeding the system can accommodate

对分析窗体结构有独到之处。可以以十六进制和十进制两种不同方式显示窗口句柄等所有数值-Analysis of the structure of the unique form. Can hexadecimal and decimal display in two different ways, such as window handle all the numerical

C++编写的一个操作系统程序-prepared an operating system procedures

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。

自己动手写操作系统-to write its own operating system

职工信息包括职工号、姓名、性别、年龄、学历、工资、住址、电话等（职工号不重复）。试设计一职工信息管理系统，使之能提供以下功能： （1）系统以菜单方式工作； （2）职工信息录入功能（职工信息用文件保存）； （3）职工信息浏览功能； （4）职工信息查询功能，查询方式：按学历、职工号查询等； （5）职工信息删除、修改功能。 -Information including the number of workers union, name, sex, age, education, salaries, addresses, telephone numbers, etc. (number of workers of non-repetition). Workers try to design a management information system so that it can provide the following functions: (1) the way the menu system to work (2) staff input function information (information workers saved documents) (3) staff information browsing (4) Information trade unions function, query methods: according to their academic qualifications, trade unions, such as its inquiries (5) information workers to delete, modify function.
