As a combination method of hardware and software in embedded systems design, reconfiguration technology has a great advantage for its reliability and system integration. Dynamic reconfiguration technology of FPGA can not only satisfy these requirements, but also strengthen the adaptivity of the system and reduce costs. In this paper, dynamic local reconfiguration was introduced and the EAPR design process was presented with improvement. Then the entire design was implemented with the Virrtex-ML403 development board produced by Xilinx to verify the validity of the method and guarantee the stability of the system. It is good for efficient management and rational utilization of resources in practical applications.
