| Abstract: | The method to realize high speed data communication between FPGA and PC parallel interface via EPP protocol is introduced.And the operational mode and communication principle of EPP are described.The hard ware designing structure,the finite state machine realization and the corresponding parallel program design are discussed.The high speed data transmission between PC and FPGA is realized.With this method,FPGA and PC are occupied less time,particularly under condition of mess data,more advantages are shown.The proposed method has some generality. |
