操作系统

The master processor is a general-purpose processor which can perform I/O operations as well as computation while running the operating system.

主处理器是一个通用处理器，它在运行操作系统的同时，能实现I/O操作以及计算工作。

CPL language based on ALGOL 60 close to the hardware, but relatively large scale, it is difficult to achieve. University of Cambridge in 1967 of the Matin Richards made to simplify the language of CPL, the introduction of the BCPL (Basic Combined Programming Language) language. In 1970 the United States Ken Thompson of Bell Labs to the basis of language BCPL, but also further simplified the design of a very simple hardware and is very close to the B language and language with B first UNIX operating system, the PDP-7 to achieve.

CPL语言在ALGOL 60的基础上接近了硬件一些，但规模比较大，难以实现。1967年英国剑桥大学的Matin Richards对 CPL语言作了简化，推出了BCPL（Basic Combined Programming Language）语言。1970年美国贝尔实验室的 Ken Thompson以 BCPL语言为基础，又作了进一步简化，设计出了很简单的而且很接近硬件的 B语言（取 BCPL的第一个字母），并用 B语言写第一个UNIX操作系统，在PDP-7上实现。

The main features and basic functions of RTX51 TINY, a small and real-time operation system, and its applications in the single-chip microcomputer systems are introduced simply in this paper, and an application example of it is given; stack configuration and the construction of task state are analyzed in detail when tasks are created, and, the memorizer manage is done in detail when tasks are switching, and the flow charts of primary codes are given in this paper.

本设计简要介绍了小型实时操作系统RTX51 TINY的主要特点和基本功能以及在单片机系统中的应用方法，并给出了一个RTX51的应用实例；详细地分析了这个内核创建任务时堆栈的配置和状态字结构及任务切换时的存储器管理，并给出创建任务及任务切换的主要代码流程图。

Virtual memory page replacement is an important part of virtual memory management.

页面置换算法是操作系统中虚拟存储管理的一个重要部分。

The OS will use all memory before trying to page.

该操作系统将使用所有内存页面之前尝试。

Operating system -- memory management page request algorithm source, the five algorithms were realized.

操作系统——存储器请求页式管理算法实现源程序，5种算法分别的实现。

In order to solve this problem, this paper first presents a transparent computing system based on the Godson platform, and then analyzes some main technologies introduced in the design, such as the multi-OS remote booting protocol, the virtual disk mechanism, the virtual memory and swapping mechanism as well as the user and resource management.

为此，文中提出了一种基于龙芯平台的透明计算机系统，着重讨论了实现该系统的一些关键技术，如多操作系统远程启动协议、虚拟磁盘机制、虚拟内存与交换机制、用户及资源管理等。

The operating system uses a portion of the hard disk as virtual memory,swapping data and instructions beween the hard disk and physical memory.

物理内存用于储存诸如操作系统、视频数据及计算机用于运行程序的指令和数据之类的内容。

Protected mode allows for 16M of memory but is also capable of protecting the operating system and programs from accident and deliberate destruction by users, a feature that is absent in the single-user 8088/8086 Virtual memory is a way of fooling the microprocessor into thinking that it has access to an almost unlimited amount of memory by swapping data between disk storage and RAM.

在保护模式下系统可用16M的内存寻址并且可防止操作系统或程序被用户不经意或故意破坏。这个特征是单用户8088/8086所不具备的。所谓虚拟内存就是通过在磁盘存储器与RAM中交换数据将微处理器骗过，使之认为它有无限大的内存寻址空间。

In fact, the folder structure of the Windows operating system is quite a complicated menagerie of files and folders.

事实上，文件夹结构的Windows操作系统是一个相当复杂的动物园的文件和文件夹。

Recall that, in the Kolmogorov axiomatization, measurable sets are the sets which have a probability or, in other words, the sets corresponding to yes/no questions that have a probabilistic answer.

延期开工的Kolmogorov宣布要衡量所有套职能有限许多坐标限制在于衡量子寅。换句话说，如果是/否的问题回答f可看的价值观念在许多最有限坐标，然后它有一个概率的答案。

The experimental results showed that the algorithm can filter singular points and remain fixity of the target edge.

实验表明：基于模糊理论的图像智能滤波方法比常规图像滤波方法运算量小，它既能去除奇异点，又能保持图像中目标的边缘不变性，具有很好的滤波效果。
