摘　　要：为解决工业测试领域中存储系统程序更新需频繁拆卸的问题且存在无上位机数据存储的特殊需求,提出基于FPGA的智能在线升级存储系统设计。系统以FPGA为主控,采用千兆以太网与FLASH组合方案,更新指令及配置文件通过千兆以太网下发到程序存储器,对SPI Flash进行分区擦除写入,从而实现FPGA程序的在线升级。同时,光耦指令解析模块使系统摆脱上位机依赖,能独立完成智能数据存储,此外,系统还集成自定义DR_UDP协议反馈可靠设计,优化了千兆以太网口的通信效率与稳定性。经功能验证分析,该系统运行稳定,灵活可靠,千兆以太网传输速率达700 Mb/s,且未发现数据丢失,可广泛应用于诸多不便拆卸的场景。To address the frequent disassembly required for program updates in storage systems within the industrial testing field,as well as the unique need for data storage without a host computer,a smart online upgrade storage system design based on FPGA is proposed.This system utilizes FPGA as the main controller and employs a combination of Gigabit Ethernet and FLASH.Update instructions and configuration files are transmitted via Gigabit Ethernet to the program memory,where they are partitioned,erased,and written to SPI Flash,enabling online upgrades of the FPGA program.Additionally,the optocoupler instruction parsing module enables the system to operate independently of a host computer,performing intelligent data storage autonomously.Furthermore,the system integrates a reliable feedback design using a custom DR_UDP protocol,optimizing the communication efficiency and stability of the Gigabit Ethernet port.Functional verification analysis confirms that the system operates stably,flexibly,and reliably,with a Gigabit Ethernet transmission rate reaching 700 Mb/s,and no data loss detected.This system can be widely applied in various scenarios where disassembly is inconvenient.
