Abstract: Aiming at the generation of high-speed modulation waveform in data storage and transmission,a design of large capacity data storage and transmission between NORFLASH and USB based on Virtex-6 FPGA is presented.The control interface of SLAVE FIFO and the controller of erasing,writing and reading NORFLASH are designed by using Verilog HDL hardware description language.Storage and playback verification of large data of 6Gbits are implemented between NORFLASH and USB.Test results show that the controller is stable,reliable and of good portability.

Key words: NORFLASH;SLAVE FIFO;parallel data modulation mode;state machine
