Abstract:

A large-capacity and high-speed data acquisition system based on DDR2 SDRAM and USB 2.0 is designed, the core controller of which is FPGA. High-speed acquisition and large-capacity storage and transmission for data are implemented employing FPGA modular programming, large-capacity data storage of DDR2 SDRAM and high speed transmission of USB. The system not only supports hot plug and plug and play, but also is used easily. The experimental result shows that acquisition, storage and transmission for data can be provided by high speed, and the maximum transmission rate can be up to 20 MByte/s. The system has a high application value in the field of high-speed sampling for signals.
