The design and realization of data asynchronous exchange protocol based on USB and FPGA
A data exchange protocol between test system and PC computer is designed based on USB2.0 controller chip CY7C68013 and FPGA. The system transmission adopts mainly GPIF mode, has achieved high-speed transmission of a variety of data between the test system and the PC host, and has met new demands of generalization of the missile telemetry automatic test system for interface technology between the test system and the PC. The paper gives the physical layer hardware circuit design of system interface, and describes how to make full use of internal resources of CY7C68013 and FPGA to achieve the transfer protocol. At present the transport protocol has been successfully used in a missile telemetry universal test instrument project.
