常用JTAG方式更新FPGA程序存在受设备自身结构形式和安装场所等因素

常用JTAG方式更新FPGA程序存在受设备自身结构形式和安装场所等因素限制，缺乏灵活性，存在拆装复杂，升级效率低和不好维护等缺点。针对此种情况，设计了一种通过串口实现FPGA更新的途径，该方法通过PC向FPGA发送所需更新程序数据，根据在FPGA内部实现的数据传输逻辑和控制逻辑，结合专用IP电路，将更新程序数据存入FPGA系统中，实现配置文件的更新。经过对FPGA系统重新加载，验证了设计的正确性和可行性。通过设备的串口实现软件更新，不增加额外的硬件开销，有效地解决设备拆装不便和操作繁琐的问题，提高了现场工作效率，节省人力成本。

The commonly used JTAG method to update FPGA program is limited by the structure and installation site of the device itself, lacking flexibility, complex disassembly, low upgrade efficiency and poor maintenance. In view of this situation, a way to update FPGA through serial port is designed. This method sends the update program data to FPGA through PC. according to the data transmission logic and control logic realized in FPGA, combined with special IP circuit, the update program data is stored in FPGA system to update the configuration file. After reloading the FPGA system, the correctness and feasibility of the design are verified. Through the serial port of the equipment, the software can be updated without additional hardware cost. It can effectively solve the problems of inconvenient disassembly and operation of the equipment, improve the field work efficiency and save labor cost.<br>
