| Abstract: | To achieve the data transfer between the FPGA and USB, this paper introduces a USB2. 0 communication hardware interface design, prograrning of USB firmware and writing Windows programs using MFC. Data stored in the FPGA is transferred with USB interface to the host computer and saved, using the synchronous Slave FIFO interface mode and Bulk transfer mode. The experimental results show that it can work properly and it can meet the USB specification and design requirements. |
