Design Of USB Communication Interface Based On Embedded FPGA

USB is widely used in computer field because of its high speed, versatility and plug and play. In recent years, popular embedded CPU chips are integrated with USB Host and Device, which makes them convenient to transmit data. And yet, FPGA is applied to all kinds of system at present. With the development of SOPC technology, FPGA becomes core CPU of embedded system from single function such as timing control or signal processing. The request for transmission data by USB is considerable increase. The paper designs the scheme of realization the USB Host and Device on embedded FPGA platform of Altera Corp. The hardware and software design are provided and verified in detail.
