Abstract
To solve the problems that in underwater multi‐channel data acquisition system cannot satisfy the high speed data rate and large storage capacity with no computer ,a disk array storage system based on FPGA is designed .IDE commu‐nication and controller run on a SOPC system based on Altera's Cyclone IV FPGA .The parameters detecting and initializa‐tion of the hard disk are accomplished ,together with the reading and writing based on PIO mode .By adopting the design of IDE/SATA dual interfaces and dual channels ,the system is based on the theory of disk array storage ,and FATFS file sys‐tem is utilized for file management ,which enables the promoting of augment ability and flexibility of the system when the da‐ta is backed up at the same time.关键词
