用FPGA实现图文电视中汉字显示系统

Design of Chinese Character Display System in Teletext Using FPGA

近年来图文电视得到了迅速发展。本设计是“图文电视”项目中的一个子项目,即设计图文电视中的汉字显示系统。本文简要介绍了图文电视的基本概念,详细描述了设计的基本思想和两个FPGA功能模块的具体实现。

Recently the technique of teletext has developed rapidly. The design presented here is a sub-project of teletext-using FPGA to design the Chinese character display system in teletext. The paper gives an overview of basic conception of teletext,and describes the basic idea of the design and the implementation of the two FPGA modules in details.
