摘要
大规模可编程逻辑器件基本组成单元包括与或阵列、查找表、多路开关和多级与非门等多种类型,通过对可编程逻辑器件的电路组成结构与基本原理的分析,并对可编程器件的在线可重构技术的方法、设计时序等进行了研究;利用多FPGA的可重构设计技术,通过修改软件设计对系统进行重构的方法,实现了对由多个部件组成的控制系统的集成,对系统进行的可重构设计与集成大大提高了原系统的可靠性、减少系统故障,降低了使用与维护成本。
The essential units of programmable logic device （PLD） in very large scale integration （VLSI） is composed by AND-OR array, look up table （LUT）, multiple switch, a^-d multiple AND-OR gate. According to the analysis of the structure and elements of PLD, a study on the way of PLD reconfigurable technology and its sequence design is made in this paper. Multi-FPGA is used in some complex system,we can change the compose and structure of hardware system by the way of changing its configure data（bit stream files）. And the way to realize system integration for some complex control system composed of many parts is presented to improve the reliability and reduce the failure for the system, which can reduce the cost of current maintenance.
