PE3200系列机汉字显示系统方案与实现

The Design and Implementation of the Chinese-character Display System for PE3200 Minicomputers

介绍一种适于中小型机的全软件汉字显示系统的设计与实现。该系统采用面向通用智能图形终端的方案,使用汉字编译方法,根据汉字输入码,生成由图形终端命令组成的汉字显示文件。通过离线预处理设计和在线点阵重定义显示方式来提高汉字显示速度。系统还提供汉字库管理和造字功能。该系统可解决由中小型机组成的过程控制系统、仿真系统和数据处理系统中的汉字显示问题。

A design and its Implementation of the Chinese-Character display system for minicomputers is introduced. The system is a general-purpose intelligent graphics terminal oriented and employs the Chinese-character compiling technique. In order to accelerate display process, the design of offline preprocessing and the mode of dot matrix redefintion are proposed and implemented. The system, implemented only by software, can be added into minicomputer-based systems such as process control systems, simulation systems and data processing systems, ets.
