摘要
针对目前航天器件大多依赖进口的现状,使用国产器件龙芯,NAND FLASH搭建了结构灵活、扩展性强的大容量存储系统。文中介绍了龙芯小系统的具体设计,并在龙芯与FPGA之间采用PCI+HPI双接口设计,由FPGA实现协议控制、切换。系统可在多模式下工作,满足多种任务对大容量存储系统的需求。PCI协议还可通过PCI/104接口引出实现多板联合,最终实现设备地检一体化。
In view of the present situation of the space component is mostly dependent on imports, domestic device to build large-capacity storage unit. Between the dragon core and FPGA double interface design, the system can work in three modes,and the protocol is implemented by FPGA, enhance the flexibility of the system, and finally realize the integration of equipment.
