摘　　要：为了满足飞管系统对1394总线配置表存储器存储容量大、读取速度快、封装小、功耗低等要求,文章提出了采用SPI串行Flash存储1394总线配置表。在对SPI协议和SPI串行Flash充分研究的基础上进行了1394总线配置表加载的系统设计、关键功能分析设计和RTL设计实现,最后通过虚拟仿真验证、FPGA原型验证及后仿真验证,结果表明该设计各项功能正确,性能满足系统要求。In order to meet the requirements of flight control system on 1394 bus configuration table memory, such as large storage capacity, fast reading speed, small package and low power consumption, SPI serial Flash was proposed to store 1394 bus configuration table in this paper. On the basis of full research on the SPI protocol and SPI serial Flash, the system design, the key function analysis and design and the RTL design of the 1394 bus configuration table loading were carried out. Finally, though the virtual simulation verification, the FPGA prototype verification and the post simulation verification, the results showed that the design was correct in various functions and the performance met the requirements of the system.
