| Abstract: | The FPGA control of the USB2.0 transmission was expounded from the system architecture and the hardware and software design.The FPGA as a main chip in hardware design answers for communication control of FT245R interface chip and reading and writing the data to SRAM;and the connection between application program and underling hardware via USB driver can achieve dada sending and displaying and storage in the host computer.The results show that FPGA can benefit high-speed data transfer via the USB interface. |
