摘　　要：介绍一种在嵌入式系统中使用ARM处理器从串配置FPGA的方法,将系统程序及配置数据存储在系统Flash中,利用ARM的通用I/O口产生配置时序,省去专用的配置PROM;详细讨论了Xilinx公司FPGA从串配置的时序;论述了S3C44B0X从串配置Spartan3E系列FPGA的软硬件实现;由于该方法在成本,体积,灵活性上的优势,将此方法应用在嵌入式系统中具有很强的实用价值。This paper introduced a method of using ARM microprocessor to configure FPGA in slave serial in embedded system. System program and configuration data were stored in Flash, the timing was generated by ARM general IO, the dedicated configuration PROM were reduced. It is presented specifically that the slave serial timing to configure Xilinx＇s FPGA. Also it gave the hardware interface between S3C44BOX and Spartan3E as well as the software realization in details. It is very practical in embedded system design for the advantage of lower cost, smaller size and more flexibility.
