A portable swappable method scientific CMOS image data storage system

In the field of deep space exploration, the detector needs high-speed data real-time transmission and large capacity storage. SATA(Serial advanced technology attachment) as a new generation of interface protocols, SATA interface hard disk has the advantages of with large storage capacity, high transmission rate, the cheap price, data is not lost when power supply drop, so it is suitable for used in high speed large capacity data storage system. This paper by using Kintex-7 XCE7K325T XILINK series FPGA, the data of scientific CMOS CIS2521F through the SATA controller is stored in the hard disk. If the hard disk storage is full, it will automatically switch to the next hard disk.
