Abstract: For some complex wireless communication systems that need multiple working modes, the resources of field programmable gate array (FPGA) may not meet the design requirements. So a method of multi-configuration of FPGA by complex programmable logic device (CPLD) is proposed. CPLD is used to store the different configuration files sent from the upper computer into the plug-in Flash, and FPGA loads different configuration files according to different needs. This method improves the utilization rate of FPGA resources, makes the program update of FPGA more convenient, and increases the flexibility of system operation.
