The dynamic reconfiguration technique based on FPGA (field-programmable gate array) can improve the resource utilization. The dynamic reconfiguration principles and methods are discussed. A remote dynamic reconfiguration scheme using Xilinx Virtex-II FPGA and SMCS Ethernet PHY (physical layer transceiver) is proposed. The hardware of system is designed with Xilinx Virtex-IIXC2V30P FPGA that embeds MicroBlaze and MAC IP core, and its network communication software based on TCP/IP (transmission control protocol/Internet protocol) protocol is programmed by loading LwIP to MicroBlaze. The experimental results indicate that the RFDRS (remote FPGA dynamic reconfiguration system) can remotely control the changes freely in the eight LED (light emitting diodes) lighting modes, which is advantageous in the system upgrade and software update, and that, using remote dynamic reconfiguration technology, the FPGA resource utilization can be reduced remarkably.
