用VHDL语言实现数字系统

Realization of Digital System with VHDL Language

通过几个例子讲述了用 VHDL 语言实现数字系统。首先介绍了多路复用器的实现 ,其次说明了用 V HDL 语言编制数字钟 ,具有时、分、秒、计数显示功能 ,具有清零、调节小时、分钟、秒的功能 ,最后谈了实现 8位通用寄存器 ,采用 VHDL语言设计数字系统是当今的趋势 ,是我国电子工业在世界市场上生存、竞争与发展的需要。

In this paper, several examples are presented to introduce the method of realizing the digital system with VHDL language. First, the realization of time division multiplexer is specified and then the digital bell with VHDL language is described which can count and display the hour, minute, second and also reset, correct, the hour, minute, second. At last, the method is presented to realize the 8 b currency register. Designing the digital system with VHDL language as the trend of development is crucial to existence and development of our electronic industry in the global market.
