摘要
介绍了1240系统(S1240)的操作系统结构,分析了操作系统与应用软件的关系,并对应用软件与操作系统的通讯方式——原语调用方式进行了剖析。分析结果表明:该系统利用软件中断方式既保证了软件的模化特性,又增强了TCPB(终端控制板)的通用性,节省了中断资源。
This paper introduces the structure of operating system used in S1240(sys-tem1240). The relationship between operationg system and application software is discussed. The PRIMITIVE call method used for communication between application software and operating system is analysed in detail. The result shows that by using software interrupt mode, this system insures the software modularization as well as enhances the universal property of the TCPB(terminal control processor board) board and thus saves the interrupt resources.
