摘　　要：针对机载平台小型化设计带来的FPGA多版本程序加载问题,提出了一种全新的FPGA多版本程序加载方法。基于“MCU+CPLD+FPGA”的硬件架构,采用在线更新+连续存储的方式进行多版本程序固化,采用ICAP3软复位启动引导方式实现任意地址段FPGA版本程序的启动。通过多重握手机制确保了程序加载的可靠性。该方案硬件实现简单,相比传统方式,可存储的FPGA程序版本有了大幅提升,且已在多个工程中成功应用。Aiming at the problem of FPGA multi-version program loading caused by the miniaturization design of airborne platform,a new method of FPGA multi-version program loading is proposed.Based on the hardware architecture of MCU+CPLD+FPGA,the method of online update+continuous storage is used to solidify the multi-version program,and the ICAP3 soft reset boot mode is used to start the FPGA program version in any address segment.The reliability of program loading is ensured through the multi-grip system.The hardware implementation of this scheme is simple.Compared with the traditional way,the version of the stored FPGA program has been greatly improved,and has been successfully applied in many projects.
