操作系统是计算机软件系统中的重要组成部分,它有效地统管计算机的所有资源,合理地组织计算机的整个工作流程,以提高资源的利用率。用户通过它可以有效地和方便地使用计算机,本文介绍武钢热连轧计算机的操作系统。该计算机系统中包括一台SCC计算机和三台DDC计算机,这些计算机都在实时操作系统管理下以多道程序方式工作,其中SCC计算机(TOSBAC-7000/25)的操作系统名为RTMOS(Real-Time Multiprogramming Operating System),DDC计算机(TOSBAC-40C)的操作系统名为POPS-C(Process OPerating System-Core)。这两个操作系统的控制思想基本相同,所不同的只是DDC计算机由于没有外存贮器,因此在存贮管理上更为简单而已。 RTMOS本身是由许多程序构成的,下面主要介绍其中的存贮管理、程序执行的控制、设备管理等功能。
The operating system is an important part of the computer software system. It effectively manages all the resources of the computer and organizes the entire workflow of the computer rationally to improve the utilization of resources. Users can use it efficiently and conveniently. This article introduces the operating system of WISCO hot rolling mill computer. The computer system consists of an SCC computer and three DDC computers, all operating in a multiprogramming manner under real-time operating system management. The operating system of the SCC computer (TOSBAC-7000/25) is called RTMOS (Real- Time Multiprogramming Operating System) and the DDC computer (TOSBAC-40C) operating system named POPS-C (Process OPerating System-Core). The two operating system control ideas are basically the same, the only difference is DDC computer because there is no external memory, so the storage management is simpler. RTMOS itself is composed of many programs, the following mainly introduces one of the storage management, program execution control, device management and other functions.
