摘要
为解决PC与FPAG的高速数据传输,通过USB实现了PC和FPGA的通信。介绍了USB接口芯片CY7C68013的基本工作原理;编写了USB固件程序和应用程序;利用从属FIFO方式,实现了数据的快速读写。测试结果表明,利用FPGA控制USB器件CY7C68013可实现高速数据传输,传输数据可靠性高。该方案完全可满足各种高速数据采集系统、移动硬盘、ATA和DSL调制解调器等接口的需要。
In order to resolve the fast data transmission between the FPGA and the PC. The communication between the FPGA and the PC are based on USB. The essay introduced the basic working principles of USB interface chip device- CY7C68013, and programming of the USB Firmware and application program. By adopting the slave FIFO model, the fast reading and writing data could be achieved. The results showed that the use of FPGA to control the USB device- CY7C68013 can improve the efficiency and accuracy of the data transmission. This project can satisfy the requirement of high-speed data acquisition system,hard disk,ATA,DSL modulate and demodulation interface.
