Reconfigurable computing of FPGA is a kind of method which can reconfigure total or partial logical sources at running time. Its key feature is the ability to increase the applicability of FPGA platform which provides a new way to the design of real- time processing ability, self - adaptability and dependability of reconfigurable system. This paper firstly introduces programming principium of reconfigurable computing and the classification and the structure of reconfigurable system, then presents three reconfigurable computing technology and their key solution in detail and makes some discussion on the key feature and the different application of the technique.%FPGA重配置技术是一种在系统运行期间对可编程器件局部或者全部逻辑资源进行实时重配置的设计方法,可以有效地提高FPGA硬件平台对系统功能的适用性,为提高系统实时处理能力、自适应能力、可靠性等方面的设计提供了一种新的思路.在对重配置技术编程原理、重配置系统分类和重配置系统基本结构等方面进行介绍分析的基础上,详细阐述了基于FPGA实现的三种重配置技术的设计思想和实现方案,并结合重配置技术的特点探讨了在不同领域的应用情况和技术要点.
