摘　　要：随着FPGA在当前嵌入式系统中的广泛应用,FPGA配置功能的模块化需求越来越强烈,FPGA配置的速率要求也越来越苛刻。鉴于主流FPGA型号配置方法和配置时序的共同点,设计提出了一种通用、快速、全国产化的FPGA配置方案。硬件电路设计和CPLD逻辑设计可以完全复用,配置速率可以获得最大程度的提高,同时设计灵活性高,能实现FPGA程序的在线更新,便于项目调试中分析和定位配置故障问题。该方案可移植性强,已成功应用于多个实际项目。Along with the widespread application of FPGA in modern embedded system,the modularize requirement of FPGA configuration become more and more strident,meanwhile the speed demand is increasingly rigorous.Considering the intercommunity of configuration method and sequence,a generalpurpose,high-speed,totally-domestic FPGA configuration method is proposed and designed.The hardware circuit and logic design can be reused,and configuration speed can be improved to the most extent,while it provides a high degree of flexibility for on-line updating program and finding problem in project debugging.This method has already got application in several actual projects thanks to the high portability.
