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Spartan-3E系列FPGA的软硬件实现。A method of using ARM microprocessor to configure FPGA in slave serial in embedded system is introduced.Store system program and configuration data in Flash memory,the timing is generated by ARM general I/O,reducing the dedicated configuration PROM. The slave serial timing to configure Xilinx＇s FPGA is presented specifically.The hardware interface between S3C44BOX and Spartan-3E as well as the software realization are given in details.It is practical in embedded system design for the advantage of lower cost ,smaller size and flexibility.
