摘要: 针对在高速调制波形产生过程中大容量调制数据传输和存储的问题,提出了基于Virtex-6 FPGA采用USB设备和NORFLASH进行大容量数据传输与存储的设计方案。采用Verilog HDL硬件描述语言设计了SLAVE FIFO控制接口,以及NORFLASH擦写、读取控制器,实现了USB设备与NORFLASH之间6 Gbits的大容量数据的存储和回放验证。硬件测试结果表明,所设计的控制器工作稳定可靠,且具有较好的可移植性。

关键词: NORFLASH, SLAVE FIFO, 并行调制模式, 状态机

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
