Design Of Data Storage And Transmission System Based On FPGA

Nowadays,the scale of sonar array is wider and wider,and the number of data acquisition channels is increasing.The demand for underwater acoustic signal acquisition devices with large data storage capacity is also growing.Because the underwater acoustic signal acquisition device works underwater,the operation steps of direct acquisition of data stored in storage medium are very complicated,which makes the data return very inconvenient.Generally,the underwater acoustic signal acquisition device has a data return interface.Because of the large amount of data storage,the high-speed transmission interface with saving return time has become the requirement of large-capacity data storage devices for underwater acoustic signals.In accordance with the requirement of high-capacity data storage and high-speed data transmission system,this paper presents a solution of data storage and transmission system based on a single FPGA master chip.The data storage system and data transmission system are designed by using the hardware platform of the FPGA,and the computer is used as the working mode of the hardware platform of the host computer to control the FPGA.When the storage command is received by the FPGA,the data storage system starts to work and saves the data in the form of files on the hard disk.When the data upload command is received by the FPGA,the data transmission system starts to work,transfers the files to the PC through the cable,and completes the data return work.The main content of this paper is the design of data storage and transmission system.The design of data storage system includes on-chip programmable system and FAT32 file system.The design of data transmission system includes Gigabit Ethernet data transmission system Finally,the function of data storage and transmission system is verified under laboratory conditions.The results show that the function of data storage and transmission system is normal,stable and meets the actual needs.
