本文以PC系列机种为例介绍了如何在微型机上实现实时操作及系统地开发实时软件的方法,文中的介绍过程也说明了它是如何提高了一个系统的全面性能的。必须指出,本文中的方法和分时多用户,是有区别的,本文中强调的是实时的方法,及多任务的通讯方法,尤指包含实时采样的控制系统。 This article takes PC series as an example to introduce how to realize real-time operation on the microcomputer and to develop real-time software systematically. The introductory process also shows how it improves the overall performance of a system. It must be pointed out that the method in this paper is different from time-sharing multi-user. In this paper, we emphasize the real-time method and multi-task communication method, especially the control system including real-time sampling.
