摘　　要：讨论了在Xilinx开发平台上利用FPGA动态重构技术实现自重构系统的方法以及流程。系统中包含静态和动态两种模块,采用Xilinx的基于模块的动态重构设计方法实现。静态模块和动态模块通过一个称为总线宏的结构通信,由嵌入式硬核处理器PPC405控制Xilinx的内部访问接口(ICAP)完成重构。实验表明采用自重构技术可以在单片FPGA上实现复杂的可重构系统。In this paper it is described that how to create a self- reconfigurable system by dynamic reconfiguration technique which is partitioned into a fixed part containing an embedded microprocessor to manage the ICAP to implement the dynamic reconfiguration process and reconfigurable parts which communicate with the fixed part through a specific structure named bus macro. The experiment shows that it is possible to implement a complex reconfigurable system in a single FPGA using self- reconfiguration technique.
