| 摘 要： | 高速图像采集技术广泛应用于图像信号传输与处理、模式识别和工业控制领域。利用FPGA技术将串行的LVDS和Hotlink格式的图像信号进行变换和处理,转换为标准的16位并行数据,再由USB接口控制芯片CY7C68013A将数据按照USB2.0协议标准,完成与上位机的数据通信。最大数据传输率可达1 764Mbit/s。

| Abstract: | High-speed image acquisition technology is widely applied in image signal transmission,pattern recognition and industrial control.By means of FPGA,serial data in format of LVDS and Hotlink is translated into standard parallel data of 16 bit.Then the data is transferred to the host computer through USB interface controller CY7C68013A,according to USB2.0 standard protocol.The max transmission speed is up to 164 Mbps. |
