Application of Remote FPGA Dynamic Reconfiguration System in LED Lighting

摘要

The dynamic reconfiguration technique based on field-programmable gate array(FPGA) can improve the resource utilization. Discussed are the dynamic reconfiguration principles and methods. Proposed is a remote dynamic reconfiguration scheme using Xilinx Virtex-ⅡFPGA and SMCS Ethernet Physical layer transceiver(PHY). The hardware of the system is designed with Xilinx Virtex-ⅡXC2V30P FPGA that embedds MicroBlaze and MAC IP core,and its network communication software based on transmission control protocol/Internet protocol(TCP/IP) protocol is programmed by loading LwIP to MicroBlaze. The experimental results indicate that the remote FPGA dynamic reconfiguration system(RFDRS) can switch freely in the eight lighting modes of light emitting diodes(LED),and that,using dynamic reconfiguration technology,FPGA resource utilization can be reduced remarkably,which is advantageous in the system upgrade and software update.
