分时操作系统

但是Linux系统本身是一个分时操作系统，所以必须对其进行实时性改造。

However , Linux is a time-sharing operating system , it must be improved for real-time .

Linux是UNIX在PC机上的实现，它是一种开放源代码的分时操作系统。

Linux is realization of UNIX on PC , and it is open source and time-sharing operating system .

可以说，Linux作为一个通用的分时操作系统，有非常大的潜力改造成为一个实时嵌入式操作系统。

It can be said that , as a general time-sharing system , Linux has great potential to transform into a real-time embedded operating system .

探讨了计算机分时操作系统将CPU资源分配给各任务的原理，研究了分时操作系统下3种主要的采样方式。

The principle of the CPU resource distribution to tasks was explored and three main sample modes were researched in sharing-time operating system .

然而Linux本身作为一个通用的分时操作系统，将它应用于实时环境有许多缺点和不足，所以要对现有的Linux进行实时化改造。

But as a general timesharing operating system , Linux has a lot of shortcomings and deficiencies when it is used under the embedded and real-time environment , so the existing Linux should be transformed .

由分析可见，Linux的功能完全符合POSIX1.0标准，是一个分时操作系统，但它又能对实时进程进行调度，具有实时操作系统的特征。

The analysis leads to a conclusion that Linux completely comes up to the standard of POSIX 1.0 , and it is a time_sharing operating system which can also schedule real time process . Linux has the characteristics of a real time operating system .

在大多数分时操作系统中，用这种转入和转出技术管理主存空间。

On most timeshared system , such roll-in and roll-out techniques are used to manage main memory space .

但是Linux是一个分时的通用操作系统，在任务调度方面采用的是公平原则，这样就限制了Linux的实时化应用，必须对其进行改进，以满足实时的要求。

But as a universal time-devision operating system , the principle of tasks scheduling of Linux is fairness , so this restricts the application of Real-time on it .

它比标准的Linux操作系统相比要小得多，同时它具有Linux系统的标志性特点，是标准的分时多用户操作系统。

The dedicated embedded Linux operating system is a standard timesharing multi-user operating system and it has main features of that kind of operating systems , but its size is much smaller compared with them .

在软件设计上，系统采用分时多任务操作系统的设计方法，用PCC自带的AB语言进行了编程，有效地提高了装置的实时性和运行效率。

In soft design , real-time multitasking dispatch system , using the AB language of PCC to program , improves the real-time propriety and operational efficiency of the instrument effectively .

由于贝加莱PCC采用分时多任务操作系统，控制程序采用模块化设计，用不同的程序实现不同的功能，并依据其重要程度采用不同的扫描周期。

Because B & R PCC uses time-sharing multi-task operation system , control program uses modularization concept , and it makes different program to realize different function , also it makes different cycle time according to the importance .

提出了基于分时操作思想的单片机系统设计方案，并给出了一具体应用的实例以及详细的实现方法。

In the paper , a design scheme of chip microprocessor system based on time-sharing is presented , and an applicable example and the realization methods are also given in detail .
