| Abstract: | A kind of multi-channel bus interface based on USB2.0 controller and FPGA is introduced.The Reading and Writing of bi-directional communication through different buses are accomplished by using FPGA,which controls the multi-channel bus interfaces,and USB2.0 controller CY7C68013,which works under the Slave FIFO mode.The simulation result shows that the design has the advantages of high integration,complete function,high transfer speed and application flexibility.This solution has been applied successfully in... |
