可编程逻辑器件及开发系统

\ \ Programmable Logic Device and development system

可编程逻辑器件（ＰＬＤ—ＰｒｏｇｒａｍｍａｂｌｅＬｏｇｉｃＤｅｖｉｃｅ）是一种可以由用户在现场进行编程的逻辑器件，它给数字系统的设计带来了全新的概念，使数字系统的逻辑规模更大，设计变得更加方便、灵活和高效。本文介绍ＰＬＤ器件的特点以及ＰＬＤ器件的开发系统。

LD (Programmable Logic Device) is a kind of logic devices, which can be reprogrammable many times (more than 1000 times). With PLD devices, one can design a digital system more convenience, more flexible and more efficient. This paper introduces the characteristics of PLD devices and PLD development system.
