摘　　要：对于一些复杂的、需要多种工作模式的无线通信系统,现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)的资源可能满足不了设计要求,因此提出了由复杂可编程逻辑器件(Complex Programmable Logic Device,CPLD)对FPGA进行多重配置的方法。利用CPLD把上位机发送过来的不同配置文件存储到外挂Flash中,FPGA根据不同的需求加载不同的配置文件。该方法提高了FPGA的资源利用率,使得FPGA的程序更新更加方便,增加了系统运行的灵活性。For some complex wireless communication systems those 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.
