FPGA和EZ_USBFX2在采集图像数据中的应用

Application of FPGA and EZ_USB FX2 in Image Data Acquisition

利用FPGA和EZ_USB FX2(CY7C68013)将MT9M112(Sensor)数据准确无损地传给PC机。方案使用CY7C68013控制器工作在Slave FIFO从机方式,用Verilog HDL语言在FPGA中产生相应的控制信号,最终实现对数据的快速传输,在上位机得到Sensor采集的清晰画面。该方案的传输速度快,数据准确,可扩展到其他需要通过USB进行快速数据传输的系统。与其他采用异步通信方案相比,设计利用FPGA缓冲作用,使数据无丢失传输,最终在上位机得到的图像更加清晰流畅。该设计方案和产品达到国际先进水平。

Using FPGA and EZ_USB FX2 （CY7C68013） to transfer the MT9M112 （Sensor）＇ s data to PC. CY7C68013 works in the Slave FIFO controller from the machine, using Verilog HDL language in FPGA to produce the control signals,and eventually make a rapidly transmission of data. This programme can transmit speedly and accurate data. Compared with asynchronous communication,using FPGA design has no loss of data, the ultimate image in PC is more clearly and fluently. The design and products reach the international advanced level.
