可编程逻辑器件在嵌入式系统中的应用

The Application of Programmable Logic Devices in Embedded System

针对当前嵌入式系统的特点 ,提出了一个采用“微控制器 +可编程逻辑器件”的系统结构来解决其所面临的问题 .这种系统结构不但可以弥补嵌入式系统本身的一些不足 ,而且加入了它原先所不具备的一些特性 .通过 2个设计实例具体阐明了如何来设计这种结构的嵌入式系统 .

An embedded system structure that uses programmable logic devices is described,which can improve the previous embedded system by enhancing the system performance and adding some new functions into the system.Two examples are presented to show the design of the new structure.
