FPGA high-speed data acquisition system based on USB communication

A FPGA high-speed data acquisition system based on USB communication is designed to solve the problems of high-speed data acquisition and transmission.The system takes FPGA as a controlling core to implement three functions of A/D control,data buffering dual-port RAM and CY7C68013A control.The programme is compiled with Verilog HDL language and ISE software to control multi-AD7356 to acquire data,store the acquired data in dual-port RAM,and control CY7C68013A to upload data to PC via USB.The experiment testifies that the system works well when CY7C68013A's transmission velocity is set as 16.7 Mb/s.
